SPPARC, the London-based architecture firm behind the £1.3 billion regeneration of Olympia, has completed its restoration of a Grade II listed Georgian townhouse near Fitzrovia’s Charlotte Street Conservation Area. Creating four floors of vibrant, modern workspace for a family office, the project has remediated the impact of previous restoration works that damaged the building’s historic charm.

The project’s architectural focal point is a hexagonal lightwell formed from hand crafted oak beams reminiscent of a honeycomb in its design. A key feature since the early stages of the concept design, this permeable form allows plentiful natural light into a dedicated social hub in the building’s modern addition, and promotes visual and physical connectivity between floors.

The oak installation is structural and supports both the hexagonal glass roof above and a new first-floor roof terrace. Individual elements that form the webbed structure were manually elevated into position over a series of weeks, with the feature held together by restraint nodes and tension rods concealed in each of the timber lengths.

While the lightwell is a focal point, the building enjoys a varied aesthetic throughout with each of the spaces and rooms enjoying a unique appearance, while reflecting SPPARC’s attention to detail. This includes warm, rich oak finishes that create a soft, natural feel. The selective use of glazed screens throughout the building opens up the space, promoting connected views into rooms and natural light throughout the inherently cellular configuration of a Georgian townhouse.

Located above the structural timber roof is a new external courtyard garden, accessed from the original main stone cantilevered staircase. Crafted from warm-toned timber beams, oak planks organically twist and turn to create an integrated balustrade and seating area, providing views through the hexagonal glass into the interior below.

The honeycomb motif is carried over to the cut-outs on a bespoke corten planter screen around the roof terrace’s perimeter that houses bee-friendly planting. This encourages pollination from working bees in an enclosure on the building’s main historic roof form.

SPPARC’s project remediates a series of previous renovation works to the building which significantly altered the second and third floors. Drawing on its expertise in successfully striking the balance between restoring and re-imagining heritage buildings, SPPARC produced a fresh design response that echoes that of the original Georgian plan form. This was informed by an extensive process studying the building’s original layout using historical documents to create a coherent yet eclectic mix of old and new features.

SPPARC carefully selected new materials that harmonised with existing decorative features. This included the restoration of historic features like the wall panelling and plaster mouldings, while incorporating new sleek, contemporary furniture, bespoke joinery, lighting and wall colours. On the first floor, a stone floor to the hallway was reinstated to complement the original stone cantilevered staircase. Other stand-out features include terrazzo formed basins and intricate detailing on the stairs and floor finishes.

The lower ground level will house a charity dedicated to ending poverty and inequality in the London Borough of Camden. The family office’s own charitable arm occupies the second floor, while other floors are dedicated to family office use.

Trevor Morriss, Principal at SPPARC, said:

“Our Fitzrovia project is the product of six years spent carefully crafting and curating a modern, best-in-class workspace that celebrates the Grade II listed building’s heritage, remediating the 1990s-era works that stripped it of its Georgian charm. The structural timber hexagonal lightwell located in the building’s social heart is a focal point, visible throughout the remodelled property, and is echoed by a warm material palette that creates a place of calm and reflection for the special family enterprise occupying the space.”
