Mosley Thorold has ingeniously revitalized a London townhouse by repositioning a staircase to become the backbone of the entire design. This victorian townhouse transformed into a modern marvel is located in De Beauvoir Town, spanning 2,900 square feet and rebuilt with a focus on enhancing light and space.

Victorian Townhouse Transformed: Unlocking Flow with Strategic Staircase Design

The original layout was hindered by a poorly placed staircase that interrupted the flow between rooms. By removing a ground-floor study and repositioning the staircase, Mosley Thorold transformed the victorian townhouse by creating a void that draws light into the home’s darkest corners. This strategic positioning offers a visual line from the entrance through a graceful sash window, directly towards the garden.

Experience Journey and Transition

The staircase serves as a central spatial device, guiding visitors through the home. The descent is marked by a sequence of reveals, from double-height sash windows to a top-lit corridor. Each level unveils new dimensions, culminating in the lower ground extension of the victorian townhouse transformed.

Main Spaces and Their Purpose

Changes in floor levels helped reshape the lower ground floor. By lowering areas like the kitchen and dining room by 600 millimeters, the design enhanced ceiling height and improved zoning between areas. The kitchen becomes an anchor for social life, featuring a custom dining table crafted with input from the clients, fostering a welcoming atmosphere.

Upstairs: A Harmonious Private Refuge

The upper levels organize into a hierarchy of private spaces, including a principal suite with a skylit ensuite, a bespoke vanity from reclaimed materials, and a dressing room along the stairwell. Diffused lighting enhances the serene atmosphere, emphasizing the textures of the interiors.

Reclaimed Materials: A Nod to History

The use of reclaimed elements like 17th-century Italian shutters and 19th-century cement tiles fosters warmth and continuity. Each piece, from bricks to wood, serves not merely as salvage but as a material history adapted for present-day living. Mosley Thorold collaborated with specialized craftsmen to accomplish the precise transformation of the victorian townhouse.

Garden and Sustainability

Outside, a tranquil English garden, crafted with landscaper Sophie Gordon, contrasts the bold exterior elements. A natural swimming pool, free from chemical treatments, embodies the eco-friendly ethos of the house. Features like air source heat pumps and solar panels augment the property’s energy efficiency.

A detail worth noting is the central staircase—a newer addition that wasn’t part of the original plan, showcasing the innovation that defines this striking renovation.
