What’s the cost for a Garage Conversion?

On average, our cost for converting a garage ranges from £15,000 to £25,000. Prices vary depending on the type of conversion. 

What’s included in the cost?

Turning your garage into a functional space involves several key steps. Here’s a closer look at what happens during the process:

1

Assessing Suitability

 

Before anything else, the garage is assessed to ensure it’s suitable for conversion. This includes checking the structural integrity, ceiling height, and any existing damp or drainage issues.

2

Planning Permission and Regulations

​

We’ll determine whether your project requires planning permission or qualifies under permitted development.
If planning consent is necessary, we’ll handle the application process for you.
Your requirements and local building regulations are factored in to ensure the space meets your needs.

 

3

Notifying Building Control

​

Once plans are finalised, Building Control is informed to oversee and approve the work as it progresses.

4

Preparing the Garage


The existing garage is stripped back to its essential structure, retaining only what’s necessary.
Structural alterations may follow, such as knocking through to connect the garage to your house or modifying the roof if required.

5

Addressing Damp and Insulation

​

Walls and floors are damp-proofed if needed, ensuring the space is protected against moisture.

Insulation is installed on walls, floors, and the roof to meet energy efficiency standards and keep the space warm.

6

Heating and Flooring

​

Underfloor heating can be added for modern comfort.
A subfloor is installed, providing a sturdy base for the final flooring material of your choice

7

Installing Openings

​

New windows and doors are fitted to let in natural light and provide easy access.

8

First Fix Work

​

At this stage, electrics, plumbing, and joinery are installed, including wiring for lighting, power outlets, and any pipework needed for heating or plumbing fixtures.

9

Walls and Ceilings

​

Plasterboarding and plastering are carried out to create smooth, ready-to-paint surfaces.

10

Final Fixtures and Finishes

​

Internal doors, skirting boards, and other mouldings are fitted.
Final flooring is laid, and lighting is installed.

11

Decoration

​

Decorate the space, transforming it into a polished, usable room that’s ready for you to add your personal touches.

12

Clean

​

Finally, we’ll hand over a stunning new space that feels like part of your home, along with all necessary certificates. Before we do, we’ll give it a full, professional deep clean so it’s spotless and ready to use from day one.

​Key Factors That Affect Garage Conversion Costs

The price will depend on a few major factors:

Purpose of the Conversion

  • Living Space: A simple living room or office typically costs less.
