Affordable Fixed-Fee Plans from £695 + VAT
Serving London & the Home Counties

​

A single garage conversion is one of the most cost-effective ways to add valuable living space to your home — without extending the property. Whether you want a home office, utility room, small bedroom or gym, converting your underused garage can transform your lifestyle and boost your property’s value.

​

At Draw Plans, we specialise in creating detailed, regulation-ready basic single garage conversion plans for homeowners across London and the Home Counties. Our designs are tailored to your home, layout goals and budget — and start from just £695 + VAT.

​

Why Convert a Single Garage?

Single garages in the UK are often too narrow for modern vehicles. In many homes, they become dumping grounds for tools, bikes, and forgotten clutter. Converting that space into a liveable room is a smart investment and can often be completed quicker and more affordably than you think.

​

Benefits of a Single Garage Conversion:

• Add 10–14 sqm of usable internal space

• Increase your home’s resale value

• Avoid the disruption and cost of a full extension

• Create the room you really need – office, bedroom, gym, studio or playroom

• Improve insulation, lighting, and energy efficiency

• Often does not require planning permission

​

Single Garage Conversion Floor Plans & Design Ideas

Designing a single garage conversion requires creativity and attention to layout. Space is limited — but with the right plan, you can achieve a functional, attractive room.

​

Popular Single Garage Conversion Ideas:

• Home Office: Add natural light, power points, heating and a built-in desk

• Small Bedroom or Guest Room: Perfect for older children or occasional visitors

• Playroom or Den: Keep toys and noise in a dedicated space

• Utility / Laundry Room: Move appliances out of the kitchen

• Hobby Room or Studio: Craft, paint or record music in peace

• Home Gym: Rubber flooring, mirrors and power for equipment

​

Tips for a Successful Single Garage Conversion

​

1. Maximise Natural Light

Replace the garage door with wide windows or French doors to bring in light and make the space feel bigger.

​

2. Level & Insulate the Floor

Most garage floors are lower and poorly insulated. Raise the floor to match the rest of your home and insulate thoroughly.

​

3. Plan for Heating & Ventilation

Extend your central heating or install electric radiators. Ensure there's good airflow to avoid damp.

​

4. Use Built-In Storage

Wall-mounted units and fitted storage will help you avoid clutter and maximise the space.

​

5. Connect It Seamlessly

Use matching finishes, flooring, and lighting to make the new room feel like part of your home — not an afterthought.

​

Do You Need Planning Permission?

Most single garage conversions do not require planning permission, provided:

• The conversion is internal

• No major changes are made to the external appearance (aside from replacing the garage door with a window or wall)

• Your home is not in a conservation area or listed

​

You will need Building Regulations approval, which ensures the new room meets current standards for insulation, ventilation, structure, and safety.

​

Our plans are prepared specifically to meet Building Control requirements, helping you avoid delays or rework.
