Planning
What should you know about planning in Hampstead Garden Suburb?
London Borough of Barnet planners are focused on suburban character, garden depths, and rear-extension precedent under Barnet's Residential Design Guidance SPD.
Planning a home project in Hampstead Garden Suburb? Our house extension and loft conversion architects can help, or you can check whether your extension needs planning permission first.
Neighbour amenity
Overlooking, daylight and sunlight typically tested at two-storey work.
Garden depth policy
Local SPDs set clear expectations on rear-extension projection.
Trees & TPOs
Mature street trees and TPOs shape foundations and consent.
Party wall matters
Most side-return and rear-extension projects trigger party wall notices — flagged upfront.
Materiality
We tune brick, render and joinery to sit calmly within the existing streetscape.
Lifestyle, sustainability & value uplift
Will a well-designed project add value to your home?
Lifestyle
Rooms that suit real life: quiet breakfasts, homework at the big table, friends round on a Friday. And a proper link to the garden.
Sustainability
We think about warmth and energy bills from the first sketch: good insulation, sensible glazing and materials that last. Not bolted on at the end.
Value
A home that works well is easier to love now and easier to sell later. Good design is usually the best-value part of the whole project.
Case study
What have we delivered?

Questions
Everything you need to know about working with DOR Architects.
Many single-storey rear extensions fall under permitted development, but flats, conservation areas, Article 4 areas and larger or two-storey schemes usually need full planning permission. We check your address against local policy before you spend money on drawings.
Yes — we work across north London and Hertfordshire and design every scheme around the local council's policies and design guidance.
First sketch to completion is typically 12–18 months — 3–4 months design, 8–10 weeks for planning, then 6–9 months on site.
We keep a small, vetted list of contractors who consistently deliver in the area — we'll introduce you at Stage 3.
Transparent stage-based fees, shared as a fixed proposal after our first meeting — no hidden hourly billing.
