Basalt House is a thoughtfully conceived renovation and extension of a Victorian terrace in North-West London, designed by EBBA Architects, a London-based studio known for their refined, materially driven architecture. With a strong focus on craft, context, and atmosphere, EBBA’s work often bridges the past and present in subtle, striking ways and Basalt House is a clear expression of that ethos.

The project blends historic character with contemporary interventions, revitalising the home through a bold rear extension in richly textured basalt stone and a loft conversion crowned by an organically shaped skylight. This new architectural language brings natural light deep into the home, with daylight cascading from the loft down through the core of the house, connecting all levels in a gentle, cohesive rhythm.

At the rear, the use of basalt stone adds depth and texture, complemented by an exposed steel lintel that introduces a subtle industrial edge. The juxtaposition of the stone’s soft, earthy tones with the steel’s clean, structural lines creates a calm, grounded atmosphere that feels contemporary yet in harmony with the building’s Victorian origins.
