De Beauvoir Townhouse | Mosley Thorold Architects

Mosley Thorold has completed the transformative renovation of De Beauvoir Townhouse, reimagining a traditional Victorian home into a refined sanctuary characterised by texture, light and reclaimed materials.

The dynamic new design balances old and new in earnest, evidenced in its craft-led approach, where technical precision and materiality play key roles throughout the home.

Appointed for their holistic approach to curating spaces, Mosley Thorold worked closely with the client even before the property had been acquired, allowing a deeper design process to understand the space and the client’s vision.

An important component of the client’s brief was to create a highly personal retreat which would equally prioritise rest and become a natural entertaining space. In order to address these new characteristics confidently, Mosley Thorold had to first review the internal circulation, which had been overlooked in its previous iteration. Disjointed spaces in the existing structure presented multiple challenges, predominantly at the entrance of the home where a poorly positioned staircase disrupted this overall flow.

Mosley Thorold has introduced new space through a series of reveals. The ground floor was opened up by removing an obstructive study and repositioning the stairwell within its footprint, in turn, improving circulation and creating a clever void that brings light into the darkest part of the plan.

Employed as a key intervention, the new staircase now serves as the central element of the home’s spatial journey, creating a striking visual connection from the entrance hall through a grand sash window, framing the direct views to the garden.

This focal adaptation through the house reveals a sequence of discoveries, from the double height sash window to the top lit corridor and finally the transition to the lower ground extension.

The lower ground floor has been reworked with strategic level changes. By lowering the kitchen, dining and reading nook by 600 millimetres, Mosley Thorold have dramatically elevated the ceiling height, improved zoning flow and strengthened the connection to the garden.

Responding to the clients wish for a home to entertain in, the kitchen now serves as the nucleus of the home. A custom dining table produced by Mosley Thorold designed personally with the client as an object that would ‘offer an embrace’ to its guests, and its connection to the surrounding living spaces, makes it an obvious place for hosting. Extending beyond the interior, the lowered patio creates a smooth transition between inside and outside through wide glazed panel doors.

The upper floors have been completely reconfigured to create a clear hierarchy of spaces, reflecting Mosley Thorold’s focus on practicality and design integrity. The client’s principal suite includes a master bedroom with an ensuite skylit bathroom, a bespoke vanity unit of reclaimed timber and a dressing room along the stairwell.

Light plays an important role as a sculptural and atmospheric element, curating a space for much needed sanctuary. Diffused top lighting accentuates the natural textures of the materials to enhance the home’s tranquil atmosphere.

The improved circulation, subtle level changes, intentional material contrasts, and strategic skylights define the spaces without interrupting the flow. The triple height hallway and new zoning create an open and continuous experience in between floors and from one living space to the next.

Reclaimed materials lie at the heart of De Beauvoir House, contributing to the warmth and richness of the interior design choices. From reclaimed 17th-century Italian shutters reworked as kitchen doors to  19th-century reclaimed cement tiles to hand selected reclaimed bricks; altogether confidently embodying Mosley Thorold’s thoughtful approach to curate well-crafted spaces that nurture long term dwelling.

As detailed in much of their work, balancing these elements required close collaboration with skilled craftspeople, including metalworkers, specialist woodworkers, a kitchen maker and an expert stonemason.

Mosley Thorold’s technical precision and material resourcefulness is underscored by their application of boardmarked concrete, visible on the external kitchen facades. The practice selected timber boards and sandblasted them to highlight the grain, ensuring the concrete cast against them would bring out the texture and relief in the final surface.

The decision to cast the concrete in a single pour, without junctions, is both a design choice and a technical challenge. Mosley Thorold designed bespoke formwork to support the concrete, including a steel column system that ensured the formwork could withstand the pressure of the pour without relying on the existing party wall.

Mosley Thorold worked closely with garden designer and landscaper Sophie Gordon, to bring about a tranquil and enveloping English garden with a dash of drama, offering a light juxtaposition to the bold steel and concrete facade.

Additionally, a natural swimming pool has been built at the rear end of the garden plot, encouraging a diverse abundance of new wildlife and ecosystems, avoiding the use of harmful chemicals. Sustainability is a thoughtful consideration throughout the project. An air source heat pump and solar panels are integrated to improve energy efficiency.

Facilitating this final fixture of urban wellness, Mosley Thorold bespoke designed a sauna and outdoor changing room, complete with a rough quarried stone facade, providing ultimate respite for the client after a nourishing dip in the pool energising start the day.

Ritual and sanctuary is characterised from house through to garden at De Beauvoir Townhouse. Mosley Thorold continues to deliver homes that celebrate meticulous craft and specialist expertise at every stage of the design, to ensure every detail is executed with precision and integrity. By layering textures and materials with care, De Beauvoir House remains grounded, characterful and deeply connected to the client.

Nathaniel Mosley, Founding Director at Mosley Thorold, said:

“Victorian buildings were crafted by hand and celebrated what materials could do. And it is the same with contemporary design. It’s about emulating the craft-led approach of that era using the tools we have at our disposal.”

Henry Thorold, Founding Director at Mosley Thorold, said:

“The journey downstairs was important to us. We wanted to be able to see the garden from the front door and to have the space open up in front of you as you walk down the steps.”
