Extension Lawful Development in Wandsworth, SW11

Project Overview

This project involved a extension at a property on Honeywell Road in Wandsworth. As part of a lawful development certificate our architects in Wandsworth 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 permitted development or maximising the potential of your home, Detailed Planning’s experience in Wandsworth 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.

As this project was pursued under permitted development rights, our strategy focused on demonstrating compliance with the relevant criteria for heights, volumes and roof profiles. Detailed drawings and evidence were prepared to support the lawful development certificate application and give the council confidence in the proposal.

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

• Rear extension designed to increase usable family space
• Lawful development submission supported by clearly coordinated drawings
• Improved connection to the garden and natural light where possible
• Comprehensive drawings and documents assembled to support the application

Outcome

The lawful development certificate was granted in September 2025, confirming that the proposal complies with permitted development parameters and can be implemented without a full planning application.

The approved scheme delivers extra ground floor space with a stronger connection to the garden, enhancing the property’s usability and value.
