Site progress in Mayfair.
This townhouse was built in 1895-97 in the Queen Anne Revival style, with a red brick facade, fireproof iron construction, and a Rococo staircase inside.
Before that, an 18th-century house stood here, home to tradesmen.
The new building was nearly twice as wide as the original, with views over Hyde Park. Its first owner was an Anglo-Greek banker who lived there until he died in 1919. In 1913–14 the house was extensively altered for James de Rothschild by the architects Romaine-Walker & Jenkins. By 1932 it was listed for sale with 9 bedrooms, 4 reception rooms, and staff quarters.
After WWII, it stopped being a family home and became offices, showrooms, then flats, a common shift for buildings in this area.

For our latest residential project, we remodelled the lower level and the back courtyard of a late Victorian building. This was to upgrade the interior and to improve the connection between the indoor kitchen and the outdoor garden.

When these buildings were originally built, the kitchen was a service space, functional, separate from family life, and often hidden from the main living areas. In today's well-being-focused society, the kitchen's function has shifted entirely: it has become one of the most important spaces of the home, serving as both a family room and an entertainment space. The design addresses this cultural shift, upgrading the existing structure to contemporary living while maintaining the quality of the building's original character.

When working with Victorian buildings, conservation restrictions often limit what can be done on the street front. The rear of the house is where opportunities lie.

In this recent project of ours, the rear, housing the kitchen, has been remodelled with a more contemporary layout, opening directly onto the rear garden, more in line with our contemporary culture of domestic living. More light, better ventilation and better access to the garden all contribute to improving everyday family life.

When reinventing old building stock, spaces are often repurposed for uses very different from their original function: think of the lower floor of a Victorian house, once occupied by servants and marked by poor lighting and ventilation, or the rear courtyards, austere, utilitarian spaces deliberately hidden from the refined interiors above.
Natural light is important, but artificial light is equally important.
The lighting technology has evolved enormously since the gas lamps of the Victorian era, redefining the everyday experience of those who use these spaces.

In our Lexham Gardens project, for instance, we turned the rear courtyard into a gym extension, giving it an entirely new role within the broader hospitality programme hosted in the Victorian building: here, lighting addresses two distinct needs, directional and energising in the training area, softer and more controlled in the surrounding spaces.

Every building carries the memory of how it was once used, and every new brief asks us to listen before we redesign.
This is exactly what happened with the Society of Genealogists, where we recycled part of the existing fit-out: the previous lighting was reused for general and desk lighting, while decorative lighting now highlights the book displays, organised along long lit shelving that enhances the user experience.

This is a story about common values.

started in 2009 from a small Los Angeles storefront, reselling retailored vintage clothing. From there, they built an entire brand around a single mission: that fashion doesn't need to begin with something new. Today, their goal is to source 100% of their fabrics from deadstock, recycled, and next-generation materials by 2030.

When we designed their Covent Garden flagship store inside a Listed Building along King Street, we found ourselves working from the same starting point. Rather than a constraint to work around, the existing heritage structure became the material we had to work with. We preserved details and retained proportions. New interventions were introduced not to detract from the existing space but to enhance its existing character.

Different disciplines, common values.

Contemporary solutions to upgrade existing buildings.

Glazing technology has evolved, creating new possibilities with thinner frames, better thermal performance, and smarter glass.
Used externally, it transforms dark or underused spaces into light-filled rooms that feel connected to the outside. The use of glass partitions internally creates dedicated zones, such as meeting rooms, offices, and quiet areas, without ever breaking the visual continuity of the whole space.
Glass unlocks the potential in existing buildings to be upgraded for contemporary everyday life.

Coleherne Court is one of London's most distinguished residential addresses, once home to iconic figures such as Lady Diana and Boris Becker. Located in Kensington Conservation Area, it includes 213 apartments.

We were commissioned with the repositioning of two apartments. The intervention worked on two levels simultaneously: changing the layout to meet contemporary living standards, improving the actual value through spatial reconfiguration, and the perceived value through bespoke, high-quality finishes, such as chevron parquet and Graham & Brown wall coverings.

Form follows culture: culture evolves, buildings need to be adapted.
