​The Keystone

Until quite recently, premium residential and office complexes in Moscow were seen as the exclusive privilege of the city center. Today the situation is changing: high-quality architecture is moving beyond the confines of the Third Ring Road and appearing on the outskirts. The STONE Kaluzhskaya business center is one such example. Projects like this help decentralize the megalopolis, making life and work prestigious in any part of the city.

The STONE Kaluzhskaya complex – three office buildings and a retail arcade – is located at the intersection of Akademik Semenikhin Street and Starokaluzhskoye Highway. Its exact address is Starokaluzhskoye Highway, 64/1, Building 1. Construction is currently in full swing. The new city block is rising directly at the exit of Vorontsovskaya metro station on the Big Circle Line (BCL).

The architectural character of this part of Moscow began taking shape in the Brezhnev era and continues to evolve today. Notable neighbors include the horizontally stretched Institute for Space Research (Profsoyuznaya 84, Building 12, 1968-1978, architect Yuri Platonov), the 22-story tower of the Central State Archive of Moscow (Profsoyuznaya 82, 2003–2006), and the Lotte Business Center (Profsoyuznaya 65, 2013, TPO Reserve). All of these buildings line one of the main arteries of the southwest – Profsoyuznaya Street. However, if you step back from this thoroughfare into the inner blocks, you will find yourself in a patchwork of irregular street grids, local industrial sites, shopping malls, and residential neighborhoods.

The area received new impetus for development with the launch of the BCL and the opening of Vorontsovskaya station. Close to the station, two large-scale residential complexes are now under construction: Architect (designed by Ingrad Project) and EVER (GAFA Architects) – together adding 300,000 square meters of housing.

When the architects at Kleinewelt began work on STONE Kaluzhskaya, they set themselves two tasks: first, to integrate the complex into the already eclectic context, and second, to anticipate its dialogue with architecture yet to come. Located right next to Vorontsovskaya metro station, the business center in a sense serves as the gateway to the district, aspiring to become the keystone of the entire area.

Structure

STONE Kaluzhskaya is a Class A office complex consisting of three towers, two of which rise from a shared podium. The total floor area is about 84,000 square meters, including 58,000 square meters of office space and 14,000 square meters of retail, cafés, and public zones.

The floor plans provide for both large open office spaces of up to 1,400 square meters and smaller modules ranging from 50 to 200 square meters. The ceiling heights reach 3.65 meters, while the double-height lobbies soar up to eight meters. Panoramic glazing ensures natural light and opens up sweeping views of the metropolitan city.

The complex is equipped with modern engineering systems and cutting-edge high-speed elevators. For motorists, there is a two-level underground parking garage for 330 cars, equipped with EV charging stations, as well as bicycle and scooter parking, car-sharing spaces, and taxi drop-off points. In front of the building, there will be a landscaped plaza with monumental art that will also serve as a public garden.

Design

The architectural company Kleinewelt and the developer STONE have long been familiar partners, having previously completed several office buildings together in Khodynka and Mnevniki. Work on STONE Kaluzhskaya progressed in a comfortable rhythm, with many iterations devoted to exploring volumetric and spatial solutions. The architects invested considerable effort into micro-level design, refining even the smallest details.

It was a careful, thoughtful process of shaping both the image and the inner content of the project, with the client actively involved. We met frequently, discussing different options. The goal was not only to create a comfortable, high-quality working environment inside the complex, but also to give it a distinctive, vibrant, and contemporary silhouette that would blend organically into the gradually evolving urban fabric of the district.


As a result, the business complex turned out distinctly abstract, without literal references, yet featuring a sophisticated asymmetrical spatial composition and varied articulation of volumes both vertically and horizontally.

The 23-story K1 tower and 13-story K2 tower stand on a three-story podium, while the 20-story K3 tower is freestanding. The upper sections of towers K1 and K3 feature cubic volumes with slanted rooflines. This solution helped avoid monotony and added dynamism to the overall composition. The “cutouts” dividing the towers into volumes also created opportunities for green terraces on the accessible rooftops.

The K2 building was conceived as the most “intimate” one of the three, housing the smallest office units starting from 46 square meters. It is designed as a parallelepiped stretched along Obrucheva Street. Directly across the street stands the equally elongated building of the Russian Academy of Sciences’ Space Research Institute. The two structures are intended to visually “rhyme” with each other.

The K1 and K2 towers connect to the podium in different ways: K2 is separated from it by a recessed strip of glazing, while K1 rests on a row of massive columns, giving the impression that the podium runs freely beneath it – at least visually.

Finally, the freestanding K3 tower features a striking detail: at the level of the seventh floor, a corner of the volume is “cut out,” creating a dramatic cantilever that hovers above the entrance. This element immediately catches the eye of people exiting the Vorontsovskaya metro station and serves as the composition’s main focal point.

In this project, the architects distilled the architectural code of the district – an area haphazardly built up with houses of varying heights and diverse geometric forms – into a concise and concentrated form.

Facades

The designers at Kleinewelt developed three types of facades, which on the one hand introduce variety into the project, and on the other ensure a clean, cohesive appearance without unnecessary complexity.

The first type is used on the main tower volumes: panoramic glazing complemented by U-shaped louvers. These louvers, made of powder-coated metal in a light gray, almost white tone, project 450 millimeters outward from the walls. As a result, the glass buildings do not dissolve into their surroundings but retain a crisp silhouette. Yet another interesting additional detail here is the blind ventilation panels, arranged in a staggered pattern.

At night, the louver lighting – an independent architectural task – highlights the geometry of the complex and lends the buildings sculptural expressiveness.

The second type is used on the facades of the upper cubes. Here too panoramic glazing is applied, yet combined with recessed ventilation panels arranged in a strict orthogonal order. The depth and articulation create an added play of light and shadow, enriching the perception of the surface. Despite its expressiveness, the system remains clean and free of excessive ornament.

The third type is the podium facades. These outer walls combine panoramic glazing with wide cornices. The glazing units are set in slender frames. The podium itself is permeable and transparent: through the central entrance, one can access the inner atrium with its escalator group leading to the upper floors, or pass straight through the building, from the metro to Obrucheva Street.

Glass

The facades are glazed with extra-clear glass featuring a reflective coating. Unlike standard float glass, it does not have the characteristic greenish tint, which emphasizes the purity and crystalline quality of the surfaces. This choice is typical of premium-class architecture, where maximum transparency and natural color rendering are crucial.

Certain recessed levels – such as those between the podium and the towers or in the upper third of the towers themselves – use glass with deliberately reduced reflectivity. It reflects almost nothing of its surroundings, appearing darker as a result. This technique highlights the facades’ complex rhythm and creates the impression that the upper blocks of the complex are floating without support.

The recessed levels are supported by columns clad in anodized aluminum. The silvery material, with its soft sheen, makes the supports appear visually lighter. These columns have a distinctive rhomboid shape, meeting the facade not with a flat face but at a rounded edge. Such subtle details illustrate the level of precision with which Kleinewelt approaches its projects.

The architects explain that they aim to avoid excessive ornamentation, typically working with a restrained set of devices, yet pushing each of those devices to perfection.

In sum, the STONE Kaluzhskaya business center combines the clarity and conciseness of geometric forms with a sophisticated overall composition, carefully chosen materials, and meticulous detailing. Kleinewelt’s design both resonates with the district’s architectural heritage and points toward its future. In this synthesis of scale, context, and detailing, STONE Kaluzhskaya truly stands out as a new landmark for southwest Moscow.

Headlines now
Architecton Awards
In 2025, the jury of the Architecton festival reviewed the finalist projects through live, open presentations held right in the exhibition hall – a rather engaging performance, and something rarely seen among Russian awards. It would be great if “Zodchestvo” adopted this format. Below, we present all the winning projects, including four special nominations.
The Silver Skates
The STONE Kaluzhskaya office quarter is accompanied by two residential towers, making the complex – for it is indeed a single ensemble – well balanced in functional terms. The architects at Kleinewelt gave the residential buildings a silvery finish to match the office blocks. How they are similar, how they differ, and what “Silver Skates” has to do with it – we explore in this article.
On the Dynastic Trail
The houses and townhouses of the “Tsarskaya Tropа” (“Czar’s Trail”) complex are being built in the village of Gaspra in Crimea – to the west and east of the palaces of the former grand-ducal residence “Ai-Todor”. One of the main challenges for the architects at KPLN, who developed the project, was to respond appropriately to this significant neighboring heritage. How this influenced the massing, the façades, and the way the authors work with the terrain is explored in our article.
A New Path
The main feature of the Yar Park project, designed by Sergey Skuratov for Kazan, is that it is organized along the “spine” of a multifunctional mall with an impressive multi-height atrium space in its middle. The entire site, both on the city side and the Kazanka River embankment, is open to the public. The complex is intended not to become “yet another fenced enclave” but, as urban planners say, a “polycenter” – a new point of attraction for the whole of Kazan, especially its northern part, made up of residential districts that until now have lacked such a vibrant public space. It represents a new urban planning approach to a high-density mixed-use development situated in the city center – in a sense, an “anti-quarter”. Even Moscow, one might say, doesn’t yet have anything quite like it. Well, lucky Kazan!
Beneath the Azure Sky
A depository designed by Studio 44 will soon be built in Kenozersky National Park to preserve and display the so-called “heavens” – ceiling structures characteristic of wooden churches in the Russian North, painted with biblical scenes. For each of these “heavens”, the architects created a volume corresponding in scale and dimensions to the original church interior. The result is a honeycomb-like composition, with modules derived directly from the historic monuments themselves, allowing visitors to view the icons from the historically accurate angle – from below, looking upward. How exactly this works is the subject of our story.
​The Power of Lines
The building at the very beginning of New Arbat is the result of long deliberations over how to replace the former House of Communication. Contemporary, dynamic, and even somewhat zoomorphic in character, it is structured around a large diagonal grid. The building has become a striking accent both in the perspective of the former Kalinin Avenue and in the panorama of Arbat Square. Yet, unfortunately, the original concept was not fully realized. In 2020, the Moscow ArchCouncil approved a design featuring an exoskeleton – an external load-bearing structure, which eventually turned into a purely decorative element. Still, the power of the supergraphic “holds” the building, giving it the qualities of a new urban landmark with iconic potential. How this concept took shape, what unexpected associations might underlie the grid’s form, and why the exoskeleton was never built – all this is explored in our article.
Resort on the Kama River
Wowhaus has developed a project for the reconstruction of Korabelnaya Roshcha (“Mast Grove”), a wellness resort located on the banks of the Kama River.
Nests in Primorye
The eco-park project “Nests”, designed by Aleksey Polishchuk and the company Power Technologies, received first prize at the Eco-Coast 2025 festival, organized by the Union of Architects of Russia. For a glamping site in Filinskaya Bay, the authors proposed bird-shaped houses, treehouses, and a nest-shaped observation platform, topping it all with an entrance pavilion executed in the shape of an owl.
The Angle of String Tension
The House of Music, designed by Vladimir Plotkin and the architects of TPO Reserve, resembles a harp, and when seen from above, even a bass clef. But if only it were that simple! The architecture of the complex fuses two distinct expressive languages: the lattice-like, transparent, permeable vocabulary of “classical” modernism and the sculptural, ribbon-like volumes so beloved by today’s neo-modernism. How it all works – where the catharsis lies, which compositional axes underpin the design, where the project resembles Zaryadye Concert Hall and where it does not – read in the article below.
How Historic Tobolsk Becomes a Portal to the Future
Over the past decade, the architectural company Wowhaus has developed urban strategies for several Russian cities – Vyksa, Tula, and Nizhnekamsk, to name but a few. Against this backdrop, the Tobolsk master plan stands out both for its scale – the territory under transformation covers more than 220 square kilometers – and for its complexity.
St. Petersburg vs Rome
The center of St. Petersburg is, as we know, sacred – but few people can say with certainty where this “sacred place” actually begins and ends. It’s not about the formal boundaries, “from the Obvodny Canal to the Bolshaya Nevka”, but about the vibe that feels true to the city center. With the Nevskaya Ratusha complex – built to a design that won an international competition – Evgeny Gerasimov and Sergei Tchoban created an “image of the center” within its territory. And not so much the image of St. Petersburg itself, as that of a global metropolis. This is something new, something that hasn’t appeared in the city for a long time. In this article, we study the atmosphere, recall precedents, and even reflect on who and when first called St. Petersburg the “new Rome”. Clearly, the idea is alive for a reason.
On the Wave
The project of transforming the river port and embankment in the city of Cheboksary, developed by the ATRIUM Architects, involves one of the city’s key areas. The Volga embankment is to be turned into a riverside boulevard – a multifunctional, comfortable, and expressive space for work and leisure activities. The authors propose creating a new link with the city’s main Krasnaya (“Red”) Square, as well as erecting several residential towers inspired by the shape of the traditional national women’s headdress – these towers are likely to become striking accents on the Volga panorama.
Valery Kanyashin: “We Were Given a Free Hand”
The Headliner residential complex, the main part of which was recently completed just across from Moscow City, is a kind of neighbor to the MIBC that doesn’t “play along” with it. On the contrary, the new complex is entirely built on contrast: like a city of differently scaled buildings that seems to have emerged naturally over the past 20 years – which is a hugely popular trend nowadays! And yet here – perhaps only here – such a project has been realized to its full potential. Yes, high-rises dominate, but all these slender, delicate profiles, all these exciting perspectives! And most importantly – how everything is mixed and composed together... We spoke with the project’s leader Valery Kanyashin.
​The Keystone
Until quite recently, premium residential and office complexes in Moscow were seen as the exclusive privilege of the city center. Today the situation is changing: high-quality architecture is moving beyond the confines of the Third Ring Road and appearing on the outskirts. The STONE Kaluzhskaya business center is one such example. Projects like this help decentralize the megalopolis, making life and work prestigious in any part of the city.
Perpetuum Mobile
The interior of the headquarters of Natsproektstroy, created by the IND studio team, vividly and effectively reflects the client’s field of activity – it is one of Russia’s largest infrastructure companies, responsible for logistics and transport communications of every kind you can possibly think of.
Water and Light
Church art is full of symbolism, and part of it is truly canonical, while another part is shaped by tradition and is perceived by some as obligatory. Because of this kind of “false conservatism”, contemporary church architecture develops slowly compared to other genres, and rarely looks contemporary. Nevertheless, there are enthusiasts in this field out there: the cemetery church of Archangel Michael in Apatity, designed by Dmitry Ostroumov and Prokhram bureau, combines tradition and experiment. This is not an experiment for its own sake, however – rather, the considered work of a contemporary architect with the symbolism of space, volume, and, above all, light.
Champions’ Cup
At first glance, the Bell skyscraper on 1st Yamskogo Polya Street, 12, appears strict and laconic – though by no means modest. Its economical stereometry is built on a form close to an oval, one of UNK architects’ favorite themes. The streamlined surface of the main volume, clad in metal louvers, is sliced twice with glass incisions that graphically reveal the essence of the original shape: both its simplicity and its complexity. At the same time, dozens of highly complex engineering puzzles have been solved here.
Semi-Digital Environment
In the town of Innopolis, a satellite of Kazan, the first 4-star hotel designed by MAD Architects has opened. The interiors of the hotel combine elegance with irony, and technology with comfort, evoking the atmosphere of a computer game or maybe a sci-fi movie about the near future.
History never ends
The old railway station in Kapan, a city in southern Armenia, has been given new life by the Paris-based design firm Normal Studio. Today, it serves as a TUMO center.
A Deep, Crystal Shine
A new luxury residential development by ADM architects is set to rise in the Patriarch’s Ponds district, not far from Novopushkinsky Square. It will replace three buildings erected in the early 1990s. The project authors, Andrey Romanov and Ekaterina Kuznetsova, have placed their bets on the variety among the three volumes, modern design solutions, and attention to detail: one of the buildings will feature smoothly curved balconies with a ceramic sheen on their undersides, while another will be accented by glass “sculpture” columns.
Grigory Revzin: “What we should do with the architecture of the seventies”
Soviet modernism came in two flavors: the good, author-driven kind, and the bad, standardized kind. The good kind was “on the periphery”, while the bad kind was in the center – geographically, in terms of attention, scale, and everything else. Can we demolish it? “That would be destroying public consensus out of thin air”. So what should we do? Preserve it, but creatively: “Bring architecture into places where it hasn’t yet appeared”. Treat these buildings not as monuments, but as urban landscape. Read our interview with Grigory Revzin on the pressing topic of saving modernism – where he proposes a controversial, yet really intriguing, way of preserving 1970s buildings.
A Roadside Picnic of Urban Planning Theorists
Marina Egorova, head of Empate Architectural Bureau, brought together urban planning theorists – the successors of Alexey Gutnov and Vyacheslav Glazychev – to revive the substance and depth of professional discourse. At the first meeting, much ground was covered: the participants revisited the theoretical foundations, aligned their values, examined a cutting-edge case of the Kazan agglomeration, and concluded with the unfathomable intricacies of Russian land demarcation. Below, we present key takeaways from all the presentations.
Perspective View
CNTR Architects has designed a business center for a new district in Yekaterinburg, aiming to reduce the need for commuting and make the residential environment more diverse. The architectural solutions are equally focused on creating spatial flexibility, comfortable working conditions, and a memorable image that could allow the building to become a spatial landmark of the district.
Malevich and Bathhouses, Nature and High-Tech
The Malevich Bathhouse complex is scheduled to open in the fall of 2025 on the Rublyovo-Uspenskoye Highway. The project, designed by DBA-GROUP under the leadership of Vladislav Andreev, is an example of an unconventional approach to the image of a spa in general and of a bathhouse in particular. Deliberately avoiding any kind of allusion, the architects opted for streamlined forms with characteristic rounded corners, a combination of wood with bent glass, and restrained contemporary shapes – both inside and out. Let’s take a closer look at the project.
Rather, a Tablecloth and a Glass!
After many years, the long-abandoned Horse Guards Department building in St. Petersburg has finally received the attention it deserves: according to a design by Studio 44, the first restoration and adaptation works are scheduled to begin this year. Both the intended function and the general scope of works imply minimal alteration to the complex, which has preserved traces of its three-century history. All solutions are reversible and aimed, above all, at opening the monument to the city and immersing it in a lively social scene – hence the choice of a cultural center scenario with a strong gastronomic component.
​Materialization of Airflows
The Nikolai Kamov International Airport in Tomsk opened at the end of August last year. We have already written about the project – now we are taking a look at the completed building. Its functionality is reinforced by symbolic undertones: the architects at ASADOV sought to reflect local identity in the architecture as fully as possible.
The City as a Narrative
Sergey Skuratov’s approach to large urban plots could best be described as a “total design code”. The architect pays equal attention to the overall composition and the smallest of details, striving to ensure that every aspect is thoroughly thought out and subordinated to the original vision. It’s a Renaissance-like approach, really – a titanic effort demanding remarkable willpower and perseverance. The results are likewise grand – architecture that makes a statement. This article looks at the revived concept for the central section of the Seventh Heaven residential district in Kazan, a composition so thoroughly considered that even the “gradient of visual emphasis” (sic!) across the facades has been carefully worked out. It also touches on the narrative idea behind the project – and even the architect’s own doubts about it.
A Garden of Hope for Freedom
In October, at the Spaso-Evfimiev Monastery in Suzdal, the Prison Yard Garden opened on the site that had served as a prison from the 18th century until the Khrushchev Thaw. The architectural concept was developed by NOῨD Short Film, and the landscape design by the MOX landscape bureau. In fact, there are two gardens here – very different ones. We try to understand whether they evoke the right emotions in visitors, while also showing the beauty of June’s ruderal plants in bloom.
A Laconic Image of Time
The Time Square residential complex, built on the northern edge of St. Petersburg, appears more concise and efficient than its neighbor and predecessor, the New Time complex. Nevertheless, the architect’s hand is clearly felt: themes of “black and white”, “inside and outside”, and most notably, the “lamellar” quality of the facades that seems to visibly “eat away” at the buildings’ mass – everything is played out like a well-written score. One is reminded of both classical modernism and the so-called “post-constructivism”.
The Flower of the Lake
The prototype for the building of the Kamal Theater in Kazan is an ice flower: a rare and fragile natural phenomenon of Lake Kaban “froze” in the large, soaring outlines of the glass screens enclosing the main volume, shaping its silhouette and shielding the stained-glass windows from the sun. The project, led by the Wowhaus consortium and including global architecture “star” Kengo Kuma, won the 2021/2022 competition and was realized close to the original concept in a short – very short – period of time. The theater opened in early 2025. It was Kengo Kuma who proposed the image of an ice flower and the contraposition of cold on the outside and warmth on the inside. Between 2022 and 2024, Wowhaus did everything possible to bring this vision to life, practically living on-site. Now we are taking a closer look at this landmark building and its captivating story.
