Expert Garage Conversion Plans from £695 + VAT - Serving London & Home Counties

​

Are you looking to add an extra bedroom without extending your home? Converting a garage into a bedroom is one of the most practical and cost-effective ways to increase living space and add value to your property. At Draw Plans, we create garage conversion plans that meet building regulations, optimise layout, and help homeowners across London and the Home Counties transform unused garages into functional, attractive bedrooms.

​

Why Convert a Garage Into a Bedroom?

A well-designed garage to bedroom conversion can give your home an extra room for guests, a growing family, or even a live-in carer or lodger. It’s quicker, less disruptive, and more affordable than a full extension — and in most cases, you won’t even need planning permission.

​

Key Benefits:

• Create a guest bedroom, teenage room, or downstairs master

• Boost your property value and market appeal

• Ideal for growing families or multi-generational living

• Save money compared to lofts or rear extensions

• Increase energy efficiency by insulating the garage

​

What’s the Cost to Convert a Garage to a Bedroom?

Best Layout Ideas for Garage Bedroom Conversions

A smart layout ensures your new bedroom feels warm, bright, and comfortable — not like a converted garage. Here’s how to get it right:

​

1. Prioritise Natural Light

Replace the garage door with wide windows or French doors to maximise natural daylight.

​

2. Insulate Thoroughly

Garage walls, floors, and ceilings are rarely insulated to habitable standards. Proper insulation is essential for comfort and compliance.

​

3. Add a Feature Wall or Built-In Storage

Make the most of the space by including storage, fitted wardrobes, or a headboard wall that doubles as a divider.

​

4. Raise the Floor (If Needed)

Many garages sit lower than the main house. Raise and level the floor with insulation and screed.

​

5. Include Heating and Electrical Upgrades

Connect the new room to the home’s heating system and ensure adequate plug points and lighting are installed.

​

6. Add an En-Suite (Optional)

If the layout and drainage allow, consider adding a small en-suite shower room to boost comfort and property value.

​

How to Integrate the New Bedroom with the House

A seamless conversion avoids the “tacked-on” feel. Here’s how to blend your new bedroom with the rest of your home:

• Create internal access from the hallway or another part of the house

• Use consistent flooring and finishes throughout

• Match paint, trim, and lighting style to adjacent rooms

• Remove dividing walls if open-plan flow is desired

​

Do You Need Planning Permission?

Most garage to bedroom conversions fall under Permitted Development Rights, so no planning permission is usually required, provided:

• The work is internal and doesn’t increase the building’s size

• It doesn’t involve converting a detached garage into a separate dwelling

• You’re not in a conservation area or listed property

​

You will need Building Regulations approval to ensure:

• Adequate insulation

• Fire safety compliance

• Proper ventilation and heating

• Structural integrity

• Safe electrical systems

​

We take care of this by producing plans that comply with the relevant parts of Building Regulations.
