Architects and Engineers in Streatham

Contemporary architecture and engineering for Victorian and Edwardian homes near Streatham Common in Streatham, from first feasibility to a finished project.

Living and Building in Streatham

Streatham High Road's townscape is predominantly late Victorian and Edwardian, with retail and commercial architecture sitting alongside large 1930s residential developments in Art Deco style.

Diagram X brings genuinely modern AEC (Architecture, Engineering, and Construction) into a district where period commercial streets meet quieter residential roads near Streatham Common.

Planning in Streatham

The Streatham High Road and Streatham Hill Conservation Area protects a long run of late Victorian, Edwardian, and inter-war commercial and residential buildings, while the separate Streatham Common Conservation Area safeguards the historic walled garden and Edwardian landscaping around the common itself.

Each scheme is assessed against the specific heritage character of whichever conservation area it falls within, rather than a single standard across Streatham.

Refurbishing in Streatham

Behind Victorian and Edwardian facades, Diagram X strips back compartmentalised period layouts in favour of open, minimalist interiors with honest materials and broad glazing.

The historic frontage stays untouched, while the space behind it becomes something unmistakably contemporary.

Construction in Streatham

Conservation area restrictions, a busy high road frontage, and densely-packed period terraces demand careful sequencing on nearly every scheme.

Diagram X runs structural engineering, waterproofing, and site logistics as one coordinated process, protecting historic character while new space takes shape behind it.
