The Garage Conversion Process
01
Initial Consultation
SwiftSpace visits your Addlestone property to assess the existing garage and understand your intended room use, priorities and budget.
02
Design and Specification
We develop the layout and project specification, selecting the most suitable insulation, finishes and services for the garage and intended use.
03
Planning and Regulations Review
SwiftSpace checks the permitted development position and identifies any planning or Building Regulations requirements before construction begins.
04
Construction
Our team completes the structural work, insulation, electrical installation, plumbing where needed, plastering and finishing in line with the agreed specification.
05
Handover and Sign-Off
SwiftSpace carries out the final checks, coordinates the appropriate building-control sign-off and hands over the completed room ready for use.
Important project guidance
Planning Permission and Building Regulations
Building Regulations usually apply
Runnymede Borough Council specifically lists changing the use of a garage into a lounge as work that will usually require Building Regulations approval. Requirements can include insulation, ventilation, structural work, fire safety, damp protection, drainage and electrical installations. Runnymede operates its own Building Control service, including surveyors covering Addlestone.

Absolutely brilliant service from SwiftSpace Garage Conversions from start to finish. We had our garage turned into a living room, and honestly, it’s one of the best things we’ve done to the house. The whole team were friendly, reliable and really easy to deal with. They turned up when they said they would, kept us updated throughout the job, and everything was left clean and tidy at the end of each day. The quality of the work is spot on. The new room blends in perfectly with the rest of the house, you’d never know it used to be a garage. It’s given us loads of extra space and has completely changed how we use our home. Couldn’t fault the experience and would happily recommend SwiftSpace to anyone thinking about a garage conversion. Thanks again to everyone involved!Posted on Google![]()

Frequently Asked Questions
-
Many straightforward garage conversions in Addlestone may fall within permitted development rights where the work is mainly internal and does not enlarge the building. However, Runnymede Borough Council advises checking whether permitted development rights have been removed from the individual property before work begins.
-
A garage converted into normal habitable accommodation will usually need Building Regulations approval. Runnymede Borough Council specifically identifies changing a garage into a lounge as work that normally requires approval.
-
The cost depends on the garage size, existing condition, intended room use and specification. Plumbing, structural changes, bathrooms and higher-end finishes can also affect the final price. SwiftSpace provides a detailed fixed-price quotation following the initial survey.
-
A garage conversion is generally quicker than constructing a traditional extension because much of the existing structure is already in place. The exact programme depends on structural work, insulation, services and the selected finish.
-
Most garages in Addlestone can be considered for conversion. SwiftSpace assesses the walls, roof, floor, damp protection, insulation requirements, access and available services during the initial survey before recommending the best approach.
-
Yes. SwiftSpace provides Addlestone homeowners with a free, no-obligation initial survey followed by a detailed quotation based on the garage, intended room use and agreed specification.
-
Yes. Subject to the existing drainage and plumbing arrangements, services can often be added for a WC, shower room, utility area, sink or kitchenette. SwiftSpace assesses the most practical connection points during the initial survey.
