Why house extensions work well in Potters Bar
Potters Bar is largely interwar and post-war suburban housing, with substantial semis and detached homes that lend themselves to extensions, loft conversions and full refurbishments. That makes Potters Bar a great place to extend into the garden or side return, and because we design and build in one team, your drawings are always buildable and your price is set early and honestly.
Planning and building control in Potters Bar
Potters Bar sits under Hertsmere Borough Council. Many rear extensions are permitted development, though depth limits and conservation areas apply, and we handle the application either way. As a design and build team we prepare the drawings and manage the whole process for you, so there is one team accountable from first sketch to sign-off.
