Architectural designers in St Neots
Our home town. We know the conservation areas, the Huntingdonshire planners and what works on the river, the Market Square and the post-war estates.
Binney & Sims is based right here in St Neots, on Huntingdon Street, and the town has been home to our studio for 13 years. We've designed extensions, loft conversions, renovations and new builds across St Neots and its neighbourhoods, Eaton Socon, Eaton Ford, Eynesbury and Little Paxton, and on the newer developments at Loves Farm and Wintringham.
Being local matters. We know the housing stock, from riverside period homes near the Great Ouse to 1930s semis and modern estate housing, and we know how Huntingdonshire District Council, the planning authority for St Neots, tends to view householder proposals.
How we help in St Neots
- Extensions and kitchen-diners on period and estate homes
- Loft and garage conversions to add bedrooms and home offices
- Renovations and remodels that modernise older properties
- New builds and plot development across Huntingdonshire
We handle the design, the Huntingdonshire planning application, and the building-regulations and structural packages, end to end.
