Mosley Thorold pulled a mispositioned staircase out from a cramped ground-floor study and made it the load-bearing narrative of an entire London townhouse. The London-based studio was appointed to renovate this 2,900-square-foot (269-square-meter) Victorian property in De Beauvoir Town before the clients had even completed the purchase, giving the practice time to understand both the building and the brief before a single wall came down. Every subsequent decision, from the lower ground floor to the garden, followed from that first structural correction.
Disjointed circulation defined the house’s previous iteration, nowhere more visibly than at the entrance, where a poorly positioned staircase disrupted the flow between rooms. Mosley Thorold’s response was to remove an obstructive study on the ground floor and reposition the stairwell within its footprint, opening up the plan and creating what the studio calls a void that pulls light into the darkest part of the house.
The relocated staircase now functions as the home’s central spatial device, creating a visual line from the entrance hall through a grand sash window and out toward the garden. “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,”Henry Thorold, founding director at Mosley Thorold, said. It is a strategy the studio has tested before, including in an earlier Victorian townhouse renovation — a maisonette in north London — where reworking the internal stair was likewise the key to resolving a fragmented plan.
A sequence of reveals structures the descent through the house, from a double-height sash window to a top-lit corridor and, finally, the transition into the lower ground extension. Nothing is disclosed at once; each level answers a question the one before it raised.
Level changes reshaped the lower ground floor more than any single material choice. By lowering the kitchen, dining area and reading nook by 600 millimeters (23.6 inches), Mosley Thorold gained ceiling height, sharpened the zoning between functions, and pulled the garden closer into the everyday experience of the lower ground floor extension.
The kitchen anchors the home’s social life, conceived from the outset as a space for entertaining rather than a service room set apart from it. A custom dining table, designed by Mosley Thorold together with the clients as part of a wider kitchen extension design, was built as an object meant to “offer an embrace” to guests — a piece whose connection to the surrounding living spaces made it, in the studio’s own account, an obvious focal point for hosting. Wide glazed panel doors extend that logic outward, lowering the patio to create an unbroken transition between the kitchen and the garden beyond.
Upstairs, the plan resolves into a clearer hierarchy of private spaces. The principal suite includes a bedroom, a skylit ensuite bathroom, a bespoke vanity unit built from reclaimed timber, and a dressing room set along the line of the relocated stairwell.
Diffused top lighting does the quiet work throughout, treated less as a utility than as a sculptural and atmospheric material in its own right, drawing out the texture of the surfaces it falls across and reinforcing the calm the clients had asked for. A triple-height hallway and the recalibrated zoning keep that continuity running between floors, so no transition from one living space to the next feels abrupt.
Reclaimed materials carry much of the house’s warmth: 17th-century Italian shutters were reworked into kitchen doors, 19th-century cement tiles were laid underfoot, and hand-selected reclaimed bricks were built into the fabric of the Victorian house extension. None of it reads as salvage for its own sake — each piece was chosen to hold its own material history inside a home built for present-day use. “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,” Nathaniel Mosley, founding director at Mosley Thorold, said.
Achieving that required close collaboration with a full roster of specialist makers — metalworkers, woodworkers, a dedicated kitchen maker and a stonemason — each brought in to execute a single material passage with precision rather than approximation.
Boardmarked concrete on the external kitchen facade demonstrates that precision most directly. Mosley Thorold selected timber boards and sandblasted them to expose the grain before casting, ensuring the texture of the wood would transfer into the finished boardmarked concrete facade. The pour itself was cast in a single, junction-free sequence, a decision that required custom formwork — including a steel column system engineered to withstand the pressure of the pour without loading the existing party wall.
Outside, the garden completes the material dialogue the house begins. Working with landscaper Sophie Gordon, the studio shaped a tranquil, enveloping English garden that plays deliberately against the boldness of the steel-and-concrete facade behind it — a brief that extended into a natural swimming pool garden, built without chemical treatment and designed instead to support its own ecosystem, echoing the same sustainability-minded approach found in Material Works’ Hackney Bay House, another Victorian renovation built around a double-height volume just south of De Beauvoir Town. An air source heat pump and solar panels round out the property’s broader commitment to energy efficiency.
A bespoke sauna and outdoor changing room, faced in rough quarried stone, closes the sequence that begins at the top of the relocated staircase — the final stop in a house designed, quite literally, to be moved through rather than simply occupied.
A detail easy to miss on a first pass through the images: the staircase now sitting at the center of the house was never meant to be there in the original plan. It was carved out of a study that no longer earns its place, and the entire building was rebuilt around the space it left behind.
