Planning in Barnet
London Borough of Barnet planners are focused on suburban character, garden depths, and rear-extension precedent under Barnet's Residential Design Guidance SPD.
Barnet officers look closely at rear projection, garden depth and the character of suburban streets, especially in Hampstead Garden Suburb and other conservation areas. We design to the Barnet Residential Design Guidance SPD.
Typical housing we see in Temple Fortune:

How we work
We start remotely: a Matterport scan gives an accurate 3D model of your home, we design options you review on video calls, then produce concept drawings. Planning and Building Regulations drawings follow only if your project needs them.

Questions
Everything you need to know about working with DOR Architects.
Often not, if it stays within permitted development limits and the house isn't in a conservation area or Article 4 area. We check your address first and can apply for a Lawful Development Certificate.
As a rule of thumb you need about 2.2m from the top of the ceiling joist to the underside of the ridge. Our 3D scan confirms this precisely.
Our Stages 0–2 (survey, existing drawings and concept design) are offered as a fixed estimated fee; planning drawings (Stage 3) and Building Regulations drawings (Stage 4) are optional add-ons only if you need them.
