Innovative rooftop extension in Hackney
A Victorian terraced house in Hackney, London, now showcases a striking rooftop extension wrapped in recycled plastic tiles that emulate natural slate. Designed by YN Studio, the project blends modern aesthetics with traditional architecture through sustainable materials and thoughtful design. The home’s new façade features rich, dark tiles that sharply contrast with the warm interiors lined with Douglas fir.

Architectural harmony through honest design
Architect Alex Smith from YN Studio describes the concept behind the extension: “We explored how a contemporary addition could harmonize with a historic Victorian street without imitation.” The materials are chosen to reflect modernity while maintaining a dialogue with the building’s historical context.

A skylit centerpiece transforms the interior
The extension revolves around a skylit staircase, creating a spacious double-height lobby visible from the entrance. White walls and Douglas fir shelving enhance this area, optimizing natural light and space. An internal window brightens the new study area, further integrating the extension with the home’s existing structure.

Smith shares, “Our most proud achievement is the double-height stair lobby. Instead of maximizing floor space, we dedicated a significant area to this vertical void, marking the project’s character and offering a generous, thoughtfully crafted environment.”

Redefining living spaces with subtle elegance
The new dormer space accommodates a skylit bedroom, featuring a Douglas fir ceiling and a central skylight. Opposite, the newly designed study fits neatly under the roof pitch, alongside a brightly skylit bathroom lined with white tiles and terrazzo flooring.

The ground floor remains primarily as is, with plans for a quarry tile-clad extension scheduled for later construction. The studio also plans an extension for the neighboring property, demonstrating their commitment to enhancing the local architectural landscape.
