Katerina Maremyanina

Architect, designer, co-founder of K&K architectural design.
Professional career since 2007. Complete design projects for residential and public spaces in Russia, England and Monaco.

It is inter­est­ing for me to con­sid­er design not as a tool to cre­ate a large num­ber of new and unique things, but as a way to think about the most impor­tant things and to free the space, and thus the mind, from unnec­es­sary things.”

Katerina Pupreva

Restoration architect, designer, co-founder of K&K architectural design.
Professional career since 2014. Design of offices and public spaces in Russia, England and Monaco.

The liv­ing space influ­ences peo­ple. The architect’s task is to make free­dom and per­spec­tive acces­si­ble to every­one, regard­less of sta­tus and class. So that both a pres­ti­gious pri­vate home and low-bud­get social hous­ing can equal­ly give peo­ple a sense of gen­eros­i­ty, hope and possibility.”

Astra Mente

Interior and product designer, artist.
Professional career since 2007. Interior design of private residences in Moscow, Italy, Portugal. Yacht and product design in Croatia.

I believe that we cre­ate our own des­tiny with every step we take in this life.
Har­mo­ny and free­dom in space is the key to bal­ance our mind and vision of the future.
Space is a liv­ing ener­gy struc­ture that we as design­ers and archi­tects must respect and work with very pre­cise­ly and accu­rate­ly to cre­ate new, invig­o­rat­ing sce­nar­ios of the flow of life within.”

We get in touch online or we meet in per­son, dis­cuss tasks and details, review cat­a­logs and ref­er­ences, plan a bud­get. Based on this con­ver­sa­tion, we draw up a detailed terms of reference.

Accord­ing to the terms of ref­er­ence, we devel­op sev­er­al lay­out options and, through sketch­es and selec­tion of exam­ples, we find an image of the future space. You com­ment, we, if nec­es­sary, modify.

The result is a pre­sen­ta­tion album with a final plan, col­lages, and ref­er­ences. These mate­ri­als cre­ate the base­ment of the Draft and Work­ing Designs.

Preliminary design.

We select spe­cif­ic fin­ish­es, fur­ni­ture, acces­sories for the set bud­get and pre­pare a three-dimen­sion­al image of the future space.

The result of this stage is a pre­sen­ta­tion album with a plan and 3D images. Based on it, a Work­ing Draft will be developed.

Working Draft.

We work out all the solu­tions in detail and trans­form them into con­crete draw­ings and specifications.

As a result, you have in your hands an album with detailed work­ing doc­u­men­ta­tion, where builders will find answers to all questions.

Project Supervision

We super­vise con­struc­tion works and mon­i­tor the imple­men­ta­tion of design deci­sions. If nec­es­sary, we mod­i­fy and sup­ple­ment the project. Dur­ing work­ing hours, we are in touch and answer all ques­tions, and also go to the site once a week until the com­ple­tion of construction.

Detailed >>>


We draw up bud­get esti­mates and a sched­ule plan of pur­chas­es. We are look­ing for the best sup­pli­ers for each posi­tion and select a man­u­fac­tur­ers of unique prod­ucts. We advise sup­pli­ers on the project and, if nec­es­sary, accom­pa­ny the client in all the steps of items order and delivery.

We coop­er­ate with var­i­ous fac­to­ries and crafts­men in Europe to cre­ate objects accord­ing to our sketches.
Thus, we are mov­ing away from inte­ri­or stan­dard­iza­tion through work­ing with cat­a­logs, and help­ing our clients to obtain the desired unique­ness of inte­ri­or items.

In addi­tion to the main project we also can help with detailed dec­o­ra­tion. This option is also use­ful if you want to cre­ate a new atmos­phere in a café, salon, home or office with­out gen­er­al recon­struc­tion. We draw up an esti­mate with­in the bud­get, select, arrange, help restore and cus­tom-make inte­ri­or items: fur­ni­ture, light­ing, vin­tage, antiques and oth­er uten­sils. We select tex­tiles and art objects.

1. Concept.

We meet in per­son or online. We dis­cuss the tasks, look at ref­er­ences, pre­dict costs. After we have con­crete data, we pre­pare a detailed design specification.
Accord­ing to the task spec­i­fi­ca­tion, we devel­op a spa­tial plan­ning solu­tion for the future build­ing in sev­er­al ver­sions, with nec­es­sary mod­i­fi­ca­tions based on your comments.

As a result, you will receive a pre­sen­ta­tion album with options for func­tion­al zon­ing, pro­jec­tion of the build­ing on the mas­ter plan, schemat­ic rep­re­sen­ta­tions of the build­ing (exam­ples, free­hand draw­ings, 3D sketches).

5. Author's supervision.

We con­trol the con­struc­tion work and mon­i­tor the imple­men­ta­tion of the design solu­tions. If nec­es­sary, we change and com­plete the project. Dur­ing work­ing hours we are in con­tact and answer all ques­tions, and once in a week we vis­it the site until the con­struc­tion work is completed. 

The cost of archi­tec­tur­al super­vi­sion depends on the size, com­plex­i­ty and loca­tion of the site.

Projects of residential and public interiors
in Monaco, London, Barcelona, Moscow.
The projects were completed during the period of cooperation
with architect Vsevolod Sosenkin.



in the city center

Cozy interior with the introduction of some antique family furniture.



Глубокие текстуры, натуральные материалы, атмосферное освещение соединились в этом минималистичном интерьере. Нашим приоритетом было отразить образ жизни и индивидуальность клиента – комфорт во всем, без визуального хаоса.

Внимание к каждой детали и акцент на основных элементах эргономики, где всё хранение объектов интегрировано в конструктивные элементы интерьера. Максимальная прозрачность и однородность в сочетании с брутальностью используемых материалов : натуральный сланец, массивное дерево, мрамор, металл с естественным окислением и стекло, вместе с теплом огня в камине помогли нам создать атмосферу спокойствия и медитации внутри шумного мегаполиса.


hotel in Dubai

When we studied the modern realities of the Arab world, we found that the demand for modernity in architecture and interior design is already very high there. In designing this project, we tried to take in considerance the context and history of the place and location, combining minimalism, classic interior design techniques and active colors.

Together with the Italian company Sicilia Intarsi, we developed a pattern for decorative panel in marquetry technic (different kind of wood inlayed together) as a transitional state between Italian classicism and modern minimalism. The main motif of the pattern is inspired by the impressions of a trip to Sicily to the workshop of Ricardo D'antone, the owner of the company.
Based on the main pattern, we have also developed modular inlayed panels, which can be assembled like tiles. If you turn them in different directions, you can create a completely different pattern. They can be voluminous and flat. Such panels were used at the bed head wall in a hotel room.

Together with Sicilia Intarsi, we presented this project at exhibitions in Paris, New York and Dubai.


private apartment

Deep textures, natural materials, atmospheric lighting come together in this minimalist interior. Our priority was to reflect the lifestyle and personality of the client - comfort in everything, without visual chaos.

Attention to every detail and emphasis on the basic elements of ergonomics, where all the storage is integrated into the structural elements of the interior. Maximum transparency and uniformity, combined with the brutality of the materials used: natural slate, solid wood, marble, naturally oxidized metal and glass, together with the warmth of the fireplace, helped us to create an atmosphere of calmness and meditation inside a noisy metropolis.

Private House

private house in Naberezhnye Chelny

The project started with the development of a functional zoning scheme and space planning specifically for the lifestyle of the customer and his family.

The site for construction is located on the banks of the Kama River. It was decided to arrange living rooms, a swimming pool, and a summer veranda so that a beautiful view of the beach opens from the windows. At the same time, it was necessary to plan the house on a long section that narrows towards the river and to orient the maximum number of windows towards the sunny sides.

Another challenge was to make this house energy efficient. All these inputs led us to the existing configuration of the house.

Teenager room

room for the boy

Task from the customer:
Create an inspiring space for learning and development for a teenager (at the time the project started, the boy was 10 years old, now He is 12).

What we did:
We removed the existing partitions between sleeping and common areas and raised ceiling as much as possible.
We conditionally divided the space into three zones: work, bedroom and relax zone.
We have placed a large number of built-in lighting and different scenarios for its use and developed built-in furniture which visually merges with the walls.

Area is 30 m2.


private apartment

The project is deliberately simple - a solid monotonous decoration of the walls and ceiling, built-in furniture, hidden sources of technical lighting. Thanks to this simplicity of the “background”, single pieces of furniture, lighting and details take on great importance and create the very essence of the interior.

We created the effect of laconic jewelry box, in this case for magnificent designer interior items.
Various lighting scenarios and well-chosen light sources also help to focus on what is important.

Home Office I

home office

We were asked to create a home office atmosphere. Our task was to reach a balance between business and informal atmosphere.

The strict negotiation area is visually separated from the soft, cozy area for relaxing and chatting with friends. The city's grey-beige gamma has become the backdrop for contemporary furniture, lighting, textures, prints and contemporary art. Elegant models of European and Japanese brands Skargaarden, Softicated, L.Ercolani have created eclectic groups of furniture with marble and wood textures.


private apartment

The apartments are located in a reconstructed historical building of the former Bolshevik confectionery factory.
The starting point for the creation of the project was a photo of a branch of grapes, which was sent to us by the customer.

To get the right shades, we made a lot of iterations.
The main storage system was custom made, with many details finalized by hand.
Wooden floor covering was additionally varnished to make the shade deeper.

In the bedroom, we spent a very long time choosing a color to get the right shade of grapes, and then accented this bright area with art.

Several scenarios were provided in the dining area. For quick breakfasts - table top that completes the main line of the kitchen. The main dining group got a place at the panoramic window.

Deep blue became the main color of the home office: the work area was highlighted with color, and the furniture was designed as a single structure.

Float room concept

float room concept

The first float rooms was introduced to the world by the American neuropsychologist John Lilly in 1972. Due to the special salt composition of water, a person is immersed in a state close to weightlessness. This contributes to deep relaxation of the body, healing of the spine, nervous system and psyche.

Today, float rooms are performed not only as closed "capsules", but also as separate comfortable rooms, including in private living spaces. One we designed in a private house by order of Float Rooms company.


renovation concept for a family club

Since this space hosts events for both children and adults, we wanted it to be universal but not boring. This was our vision - plain white with bright accent columns made of non-ferrous metal. The windows are closed with shutters, the ceiling turns into a starry sky, and the columns become even brighter in lighting.

Chernyakhovsky 19

private apartment

The work on this layout took a lot of time. It was quite complicated as many functions had to be accommodated in a relatively small space in the apartment.
The design concept was created quite quickly - a graphic contrast of white and black, complex undercuts and seams, a simple and clear form of interior items. The idea of the bedroom was inspired by the wonderful, but almost forgotten architect David Hicks. The small space turned out to be cozy and functional despite the area.

The same style were repeated in the guest bathroom and the hall.
The project was developed in collaboration with the A4 bureau.


barbershop in Moscow

When the client called us and offered to design a new barbershop, the first thing we thought of was "we have to get him away from peeling bricks, leather sofas and horns on the wall".
It was a pleasure that the client was the first to share the idea of a minimalist and bright space. Thanks to this understanding, the concept was quickly implemented. The only decorative accent was the ceiling - suspended polished steel coffers.



We were asked to develop a pilot project for the chain of clinics. The first clinic is located in Moscow, in the building of the 70s. The first thing we noticed at the entrance was that shell rock which was used for decoration almost in all public areas. The idea to use this material in the decoration of future interiors became the basis of the concept for the entire chain of clinics.

The clinic specialises in modern methods with innovative technological equipment to make treatment for pathologies of the circulatory organs. Our task was to create a minimalistic, futuristic and at the same time cozy space for unlicensed premises. We really wanted to create a public space that was different from the typical cold medical offices, where people feel uncomfortable and experience unnecessary stress.



The concept was inspired by the scenes from Andrei Tarkovsky's Solaris movie.
Our project became a synthesis of two opposites: simplified virtual and living bionic worlds.

We cannot imagine our everyday life without rapidly developing technologies. Technology is mobile, nature is a constant. We believe that humanity should move forward with an eye to its origins. We combined smooth forms, eco-friendly materials and wildlife with progressive solutions in the design concept of this office.

The project came into shortlist.
Created in collaboration with Ia Litvinova.

Home Office II

home office

The inspiration for the project was the work of the Chinese photographer Don Hong-Oai - "Waiting".

Warm colors and Chinese motifs are combined here with modern pieces of furniture and lighting. The interior tells a story without losing its function. It provides a place for work, meetings and for relaxation in an almost cosy home atmosphere.

Floral Shop

flower shop Jolly Bunch

Despite the good location at the entrance of the market, the store was hardly noticeable before. We have changed the layout of the space: so that large transparent showcase-refrigerator with flowers is visible immediately at the entrance. Also, the second entrance was integrated in plan. So, the shop became a walk-through.

The hand-made panel made of threads became a bright accent.

Mostly all functional solutions were made with minimum budget: painting the walls and ceiling, a built-in wardrobe made of laminated chipboard, a light transparent lattice shelf made of metal mesh.

Private house in Almaty


The project was designed as a house with apartments for several families with agricultural lifestyle. The project was realised in 2012.

Each apartment is located on its own level. This creates the feeling of an individual living space. The idea got along well with reality: the site is located on a mountain slope, so that the shift in levels looks natural and the facade resembles a stylized mountain range.
