Architects and Engineers in Eltham

Local knowledge of Eltham's medieval palace, its Art Deco reinvention, and the protected character of its early garden suburb estates, from first feasibility conversation through to a finished project.

Living and Building in Eltham

Eltham already holds London's boldest precedent for old meeting new: in the 1930s the Courtaulds built a genuinely radical Art Deco mansion directly against the medieval great hall of Eltham Palace, creating one of the country's great contrasts between historic fabric and confident modern design.

Diagram X brings that same spirit, real architecture, engineering and construction working together, to the homes and estates that now surround it.

Planning in Eltham

The Progress Estate, a 1915 garden suburb built for Woolwich Arsenal workers, was designated a conservation area in 1971 with an Article 4 direction restricting alterations to front and side elevations, roofs, windows, and doors.

Eltham Palace's own conservation area carries similarly close scrutiny, and the borough's various 1920s-30s council estates each bring their own character considerations to any scheme.

Refurbishing in Eltham

Across Eltham's garden suburb cottages and interwar semis, most interiors have had little meaningful updating since they were built, so a refurbishment here is fundamentally about bringing a home up to a proper modern standard of light, layout and performance.

Where a genuinely worthwhile period detail survives, a door, a fireplace, a window, we retain it deliberately, but it's never the starting assumption.

Construction in Eltham

Protected estates like the Progress Estate require close attention to a cohesive streetscape, so even modest works are assessed against neighbouring properties as much as the house itself.

We manage that consent process alongside the structural realities of working on nearly a century of consistent suburban building stock, so Eltham's estates keep their distinctive character while individual homes are quietly transformed inside.
