Curved brick apartment building with balconies and windows against a clear blue sky.

Located in the Lisson Grove conservation area adjacent to the Grade 2* listed Christ Church, this residential scheme is comprised of 49 new apartments and penthouses arranged around a landscaped communal garden, alongside two family terraced houses on Ashmill Street.


Taking inspiration from the surrounding late Victorian and Georgian terraces and Christ Church, the design reinstates the historic street frontage thereby reinforcing the character of the conservation area. Facades of fluted brick facades that subtly vary in dimension and tone of brick reflect the rhythms and proportions of the surrounding streets in a design that is contemporary yet rooted in its context. The dwellings are designed to be open plan to maximise daylight to all spaces with high ceilings and generous living space throughout.

The sale of private homes is helping to cross-subsidise affordable homes and community infrastructure as part of the Church Street regeneration scheme.
