This project transforms a former neighbourhood shop in Arroios into a place to taste wine, listen, talk and connect.

Moradia
Cepas

´

The intervention on the house in Rua das Cepas addresses a very typical condition of 1990s suburban housing in Cascais.

Moradia
Pampilheira

In Pampilheira, Cascais, the starting point is not a blank canvas: it is a house that, for years, was two independent apartments, with separate entrances, different floor levels and a very fragmented way of living.

Identity through Space!

refurbishment with a strong sense of place- Interior architecture & identity

Hotel Flow Benguela

For Flow Hotel Benguela we worked on a large, existing structure – originally conceived as a very generic building – and turned it into a hotel with a clear character, always keeping cost control in mind. We retained as much as possible of the original construction – façades, circulation, base finishes, bathrooms and part of the built-in joinery – and focused the investment on high-impact areas: common spaces, material language, lighting, landscape and loose furniture.

The concept is rooted in the territory – a real sense of place – drawing on the earth tones of Benguela, dry textures, warm light and tropical vegetation. A palette of sand and clay colours, natural materials and abundant greenery ties the whole project together: the refreshed façades bring the volume closer to the landscape, the arrival sequence is redesigned with palm trees, structured paving and a reception portal that clearly marks the sense of arrival.

On the ground floor, the programme is reorganised to create a true social heart: an open lobby, lobby bar, restaurant with terrace, outdoor lounge, cowork area and conference rooms, all connected by a fluid circulation that supports different uses throughout the day. The atmosphere is timeless and comfortable, with timber panelling, lattice screens, generous sofas, communal tables and lots of indoor planting. The restaurant spills out towards the pool area, with a light canopy and lounge zones where stone and greenery take centre stage.

In the guestrooms the strategy is smart reuse: existing floors and wardrobes are kept, reinterpreted with new finishes, headboards, lighting and loose pieces designed by the team. The result is a contemporary, bright and functional room, anchored in the reality of local construction and budget.

Most of the furniture – from reception desks, shelving and decorative screens to bespoke tables and outdoor pieces – was designed specifically for the project and produced in Benguela with local factories and workshops. This combination of reusing what is there, upgrading what is seen and working with local makers turns Flow Hotel Benguela into a coherent, grounded and sophisticated destination built from an already existing structure.

spatial layout, lighting and custom-made built-in furniture, which structures the space, integrates storage and gives the apartment its identity.

Duplex Apartment
Ribeira das Vinhas, Cascais

Full renovation of a three-bedroom duplex in Cascais, with a complete reorganisation of the layout and new openings to bring in natural light and connect the apartment directly to the large roof terrace. The aim: to transform a dated property into a contemporary home designed for everyday living.

On the main floor, the social area was redesigned as one continuous space, yet with clearly defined zones for living, TV, dining and a small reading/work corner. These areas are articulated through the spatial layout, lighting and custom-made built-in furniture, which structures the space, integrates storage and gives the apartment its identity.

Between the entrance and the kitchen, the original bathroom – large but inefficient – was completely rethought. In its place, a new spa area was created, with sauna, steam room and a full bathroom inside, complemented by a separate guest bathroom facing the entrance, more suited to daily use and receiving visitors.

On the lower floor, a simple circulation space was transformed into a stepped cinema room, creating an immersive and comfortable environment. Two “windows” with simulated indirect light were designed here to soften the feeling of a basement level and bring a more domestic atmosphere. The bedrooms were updated to a more contemporary logic, with sleeping and working zones clearly separated, and wallpaper panels defining the character of each room. The master suite was reconfigured, bringing the bed to the foreground at the entrance and fully redesigning the existing bathroom for better balance and functionality.

On the rooftop, the terrace now works as a true extra room: outdoor kitchen, dining area, sun deck and water area turn this level into a natural extension of the living space.

The apartment is now almost unrecognisable compared to the original, not through dramatic gestures, but through precise design decisions and the careful use of fixed furniture, which played a crucial role in its final character. A project that shows how the same structure can accommodate a completely new way of living.

The volume opens to the south and west with large continuous glazing

Quinta das Acácias
Malveira da Serra, Cascais

On a 10,000 m² plot on the slopes of Malveira da Serra, the existing house sat on the hillside with an outdated architecture and a weak relationship to its surroundings. The starting point for the project was clear: keep the footprint, respect the place and the spirit of the original home, but design a new architecture worthy of the protected landscape where it stands.

The new house now grows out of the mountain instead of simply resting on it. Three horizontal platforms follow the natural topography, organising the project into a lower ground floor, main floor and roof level. The volume opens to the south and west with large continuous glazing, framing the valley and distant sea views, while the northern side remains more solid, anchored into the rock. The pool follows the same logic, integrated on one of the garden terraces in direct continuity with the living room and outdoor lounge.

The programme is laid out in a clear and functional way:

Lower ground floor semi-embedded in the slope, with lounge, wine cellar, spa with sauna and steam room, two guest suites and technical areas, all linked to the patio and pool.
Main floor as a large social open space – living, dining and kitchen – sheltered by a deep overhang, plus the master suite and additional suites, each with direct access to terraces and gardens.
Roof level turned into a belvedere and dry garden, a third layer of connection to the landscape and the sky.

The architectural language relies on a restrained palette: light stone inspired by local geology on the façades, exposed concrete and strong horizontal slabs, warm timber on ceilings and frames, and generous glass surfaces to bring in light and views. Inside, the same neutral base is animated by colour in textiles and bespoke pieces – including rugs in warm tones echoing the sunsets over the hills – bringing a domestic scale to a house that is deeply connected to nature.

Outside, the slope is shaped with green terraces, stone paths and native planting, reinforcing the integration in the Natural Park and reducing earthworks. Structural rehabilitation of the existing house, reuse of infrastructure and optimised solar exposure and cross-ventilation complete the project’s sustainable strategy.

In the end, Quinta das Acácias remains exactly where it has always been – with the same view and the same bond to the mountain – but with a new, coherent and grounded architecture, ready for several more decades of life in Malveira da Serra.

the house still reads as a familiar Portuguese townhouse.

Tramagal Townhouse
Renovation of a village house with garden

Set between two party walls on Rua das Laranjeiras in Tramagal, this small village house reached us at the end of its life: worn façades, unfit interiors and an underused backyard. The goal was simple and demanding at once – restore its dignity, bring it up to contemporary comfort standards and create a clear, generous relationship with the garden.

The starting point

We kept the scale and character of the street: traditional pitched roof with clay tiles, aligned openings and soft yellow window frames. The façade is restored rather than reinvented. Windows, insulation and services are all upgraded, but the house still reads as a familiar Portuguese townhouse.

The new interior

On the ground floor the spaces are largely open. The entrance leads into a generous living area that flows into an L-shaped kitchen, conceived as the heart of the home. A large glazed opening connects this level to the patio and to the new volume at the back of the plot, blurring the boundary between inside and outside.

This floor also includes a guest bathroom and a compact technical/laundry area, carefully integrated into the joinery.

Garden and rear pavilion

The backyard becomes a real garden-patio: permeable surfaces, lawn, an exterior sink/wash area and a new single-storey volume with full-height glazing facing the green. This pavilion can work as a summer living room, home office or dining room, adapting over time to the needs of its occupants.

Private areas

The first floor accommodates the bedrooms: a master suite and a second bedroom with its own bathroom. A wide corridor with built-in wardrobes and a reading nook by the windows acts as an extension of the rooms, making full use of the depth of the house.

Light, materials and comfort

The project relies on a restrained palette: light walls, warm timber flooring, natural stone in key areas (kitchen, exterior sink, bathrooms). Indirect lighting defines paths and surfaces, ensuring visual comfort without decorative excess.

The result is a compact, efficient and bright home that respects the memory of the street while responding to how we live today – continuous, flexible spaces, closely connected to the exterior and designed for real, everyday use.

contemporary atmosphere with very clear roots in the Angolan landscape.

Restaurante Marginal
Luanda, Angola

On Luanda Bay, Marginal VIII Restaurant is born from the reinterpretation of an existing building, transforming it into a meeting place between the city, the sea and the African light. Maison34 was responsible for the interior architecture concept, spatial design and the selection of materials, furniture and lighting, creating a contemporary atmosphere with very clear roots in the Angolan landscape.

The starting point is simple: a solid base in earth tones that anchors the building to the waterfront, and a new glazed volume that crowns the whole and lets the sky in. The façade plays with arches, solids and voids, and a colour palette inspired by adobe, brick and local stone. At night, the lighting traces the rhythm of the openings and reinforces the restaurant’s presence on the seafront.

Inside, the project avoids right angles whenever possible. Curves guide the eye and the route, the ceilings are shaped as if carved out of rock, and arched openings repeat at different scales, creating a strong and coherent identity in every space. The large glazed structure acts as the guiding motif of the composition: a metal and glass grid that reveals the sky and brings greenery into the scene.

The restaurant is organised over several levels. On the ground floor, visitors are welcomed into a space of exposed brick and glass, with generous ceiling height and views over the main dining room. The dining areas are arranged around a large central void and extend into an outdoor patio, where climbing vegetation and grazing light reinforce the connection to Luanda’s climate. On the upper floors, rooms with distinct atmospheres appear – more intimate, with colour covering walls, ceilings and floors – together with a bar that reprises the language of arches and illuminated niches.

The materiality is designed to have character and, at the same time, withstand intensive use: neutral, irregular finishes, timber, metal, brick and pigmented render in warm tones. The lighting combines striking pendant fixtures with indirect light, carefully integrated into coves, niches and “false” structures that sculpt the volume of the spaces.

The result is a restaurant that is not just a place to eat, but an immersive setting: a sequence of rooms, patios and viewpoints where the gastronomic experience is accompanied by a powerful spatial experience. Marginal VIII thus asserts itself as a signature project, in which Maison34 brings to Luanda its way of working with interior architecture: built on a clear concept, respect for the existing and obsessive attention to detail.
