UK Garage Conversion: Planning, Design, and Cost Guide

Converting your garage into a liveable space in the UK can add significant value to your property and provide additional usable space. 

Here’s a comprehensive guide on how to convert your garage:

1. Planning and Regulations

a. Planning Permission

When Required: Generally, planning permission is not required if the conversion work is internal and does not involve enlarging the structure.

However, if your property is a listed building or in a conservation area, you may need permission. Check our blog on permitted development.

Building Regulations: Converting a garage will require building regulations approval to ensure that the new room is structurally sound and energy-efficient. This includes aspects such as structural stability, fire safety, insulation, ventilation, and electrical safety.

Consult Local Authorities: It’s crucial to check with your local planning authority to confirm the requirements specific to your area.

2. Design and Planning

a. Purpose of Conversion

Living Space: Consider converting your garage into a living room, bedroom, or home office.

Functional Space: It can also be used as a home gym, playroom, or utility room.

Multifunctional: Design the space to be flexible, accommodating different uses over time.

b. Layout and Design

Lighting: Ensure there is adequate natural light. This might involve installing new windows or converting the garage door into a wall with windows.

Heating and Insulation: Proper insulation is essential to make the space comfortable. Consider underfloor heating or extending your home’s existing heating system.

Access: Ensure the new room is easily accessible from the main house. You may need to create an internal doorway.
