01Extending in Weston-super-Mare
The houses here, and how they extend.
Weston has some of the biggest roof spaces in North Somerset. The Victorian and Edwardian terraces and villas near the seafront are tall, often already three storeys, with steep roofs that can take a proper room without changing the shape of the building much.
Inland, around Worle and Milton, it is a different housing stock again: interwar semis, post-war estates and bungalows, where a dormer or a roof alteration is usually what makes the numbers work.
Seafront properties need materials and detailing chosen for salt-laden air. Further inland the plots are more generous, and a rear extension can open the back of the house up properly.
02Planning & approvals
What your project is likely to need.
North Somerset Council is the planning authority, and several parts of central Weston are conservation areas where permitted development is restricted. We will explain what applies to your street before any work is priced.
Building Regulations approval is needed for every loft conversion and extension. Planning permission is not always — and where a shared wall is involved, the Party Wall Act usually is. We will go through all three with you before anything is priced.
