Extension Approval in Barnet, N11

Project Overview

This project involved a extension at a property on Brunswick Crescent in Barnet. As part of a planning application our architects in Barnet provided full architectural and planning services. The proposal sought to increase usable space and improve the connection to the garden.

Working with us gives homeowners access to expert guidance at every stage. Our architectural design services ensure that each scheme is meticulously developed, while our design process keeps clients informed and involved throughout.

Whether it’s securing planning permission or maximising the potential of your home, Detailed Planning’s experience in Barnet helps unlock opportunities and manage risks effectively.

Design & Planning Strategy

Careful consideration was given to the scale, massing and roof form of the extension to ensure it reads as a subordinate addition and preserves neighbour amenity.

From a planning perspective, we assessed issues such as daylight, privacy, overlooking and the relationship to neighbouring properties. The design balanced the client’s objectives with the Barnet planning policies, resulting in a scheme that could be supported by the council. As experienced planning consultants, we navigated the policies and liaised with officers to achieve a favourable outcome.

Our team coordinated the preparation of architectural drawings, planning statements and supporting documents, submitting a comprehensive package to the council and liaising with officers throughout the process.

Project Highlights

Outcome
