Award-Winning Design & Build for Camden's Period Properties
Camden encompasses some of London's most architecturally varied residential areas. From the elegant Georgian terraces of Regent's Park and Primrose Hill to the Victorian streets of Kentish Town and Tufnell Park, the borough's housing stock spans two centuries of domestic architecture. Much of it sits within conservation areas, making building work here more complex than in many other parts of London.

Our in-house team delivers everything: architecture, structural engineering, planning applications to Camden Council, construction, and project management.

- HOUSE EXTENSIONS
House Extensions in Camden — From Primrose Hill to Kentish Town
Camden's diverse housing stock creates different extension opportunities depending on location. The Georgian terraces near Regent's Park require the most sensitive design approach. The Victorian streets of Kentish Town and Tufnell Park respond well to the side return and rear extension treatments that have transformed similar properties across London.

Renovations in Camden — Georgian Elegance to Victorian Character
Camden's residential properties span from grand Georgian townhouses near Regent's Park to solid Victorian terraces in Kentish Town. Renovation work varies accordingly — from sensitive restoration of listed Georgian interiors to comprehensive modernisation of Victorian layouts. Structural reconfiguration, high-specification kitchens and bathrooms, rewiring, replumbing, and period feature restoration are all within our scope.
Typical costs: kitchen renovation £30,000 to £65,000, bathroom renovation £14,000 to £30,000, structural reconfiguration £7,000 to £16,000, whole-house refurbishment from £100,000 upward. Detailed quotes provided. Final costs confirmed once designs and structural requirements are agreed.
- ARCHITECTURE
In-House Architecture — Camden Council Planning Specialists
Camden Council receives one of the highest volumes of planning applications in London. Our architects submit to Camden regularly and understand the borough's design expectations across its diverse housing stock — from Regent's Park's listed Georgian terraces to Kentish Town's Victorian streets. Camden's conservation area policies, basement development requirements, and approach to heritage applications all require specialist knowledge that comes from regular submissions.
The integrated design and build model ensures buildable, accurately costed designs from the outset. Camden's varied property types each present different structural and construction challenges that our architects address at the design stage. Every project includes: measured survey, concept designs, 3D visualisations, construction drawings, planning applications to Camden Council, heritage statements where required, structural engineering, and building regulations via LABC. All included in your quote — no separate architect fees.
