Architects and Engineers in Thamesmead

Local knowledge of Thamesmead's pioneering new-town architecture and Peabody's ambitious regeneration masterplan, from first feasibility conversation through to a finished project.

Living and Building in Thamesmead

Built from 1968 on former Royal Arsenal marshland, Thamesmead was conceived as a genuine town for the 21st century, its distinctive brutalist estates, lakes, and waterways giving it a character unlike anywhere else in London.

Diagram X brings architecture, engineering and construction together across a place now being reimagined by its landowner Peabody in one of the capital's largest regeneration programmes, without losing the qualities that made the original vision so bold.

Planning in Thamesmead

Thamesmead's layout of neighbourhoods, open spaces, lakes and waterways plays a defining role in its character, so schemes near its Sites of Importance for Nature Conservation and archaeological features are assessed with particular care.

The area's ongoing masterplan, alongside a planned DLR extension bringing Thamesmead its first rail connection, is reshaping planning priorities across the town as tens of thousands of new homes are brought forward.

Refurbishing in Thamesmead

Much of Thamesmead's housing stock is distinctly of its era, honest concrete construction and generous communal layouts that modern living standards haven't always kept pace with.

Diagram X works with that structure rather than against it, bringing genuinely considered, pared-back design to interiors while respecting the integrity of the original architecture.

Construction in Thamesmead

Thamesmead's concrete-framed buildings and waterside setting both demand particular structural and environmental expertise, from understanding original construction methods to managing proximity to lakes and ecological sites.

We plan for that alongside the practicalities of building within one of London's most actively evolving masterplan areas, so new work complements Thamesmead's ongoing transformation.
