Space, Landscape and the Confidence to Design Well
Mill Hill is different. It’s not just another residential district — it’s a patch of North London where the countryside still lingers, where streets are leafy, plots are generous, and homes feel set apart.
But with those benefits come planning sensitivities: Green Belt protections, conservation boundaries, and neighbours who care what’s built next door. That’s where DOR Architects brings real value.
Whether you’re planning a contemporary new-build on The Ridgeway, replacing a tired house off Hammers Lane, or unlocking the potential of a backland site near Mill Hill Broadway, we deliver beautiful, buildable architecture — with planning intelligence baked in from the start.
“Our client in Mill Hill said they wanted their new house to feel ‘like it had always been there.’ That’s the kind of challenge we like — and exactly what Mill Hill deserves.”

Planning in Mill Hill: What to Expect

Replacement dwelling guidelines (volume, height, materials and siting)

Conservation Area controls, especially around The Ridgeway and Mill Hill Village

Backland and garden development resistance based on impact and density

Biodiversity, tree and drainage requirements for semi-rural and sloped sites

FAQs – Mill Hill Architecture & Planning
Possibly — but only under specific circumstances. We regularly help clients secure planning for replacement dwellings, limited extensions, or sensitive schemes that meet policy tests.

You may be able to — but access, privacy, and scale are major considerations. We advise early on viability and can support successful small-site schemes.
Yes. We assist with land strategy, feasibility, planning and design for 1–20 unit schemes, replacement dwellings and small-scale luxury housing.
