Double Garage Conversions: Design Ideas and Costs

February 17, 2025|News

Are you looking to make better use of your double garage space? Converting a double garage into valuable living space is becoming increasingly popular among homeowners in the North East.

With a typical double garage offering around 300 square feet of floor space, the possibilities for transformation are extensive. Many families are discovering that their unused garage space holds the key to solving their need for additional living space without the disruption of moving house.

At Tyneside Home Improvements, we help homeowners across the North East transform their properties by converting a garage into a functional and versatile living area.

Why convert your double garage?

Many modern cars are too large for traditional garages, leaving these spaces underutilised or simply used as a storage space. A double garage conversion can create additional living space without the complexity and cost of a traditional house extension.

The generous dimensions of a double garage provide enough room to create extra living space that can significantly improve your lifestyle.

Whether you’re seeking a spacious home office, a guest suite, or a family room, converting your garage could be the perfect solution for maximising your property’s potential.

Inspiring ideas for your new living space

The size of your garage offers remarkable flexibility in design and usage. A converted double garage can become virtually any type of room you can imagine.

  • For those embracing remote work, a spacious home office provides a professional environment separate from the main house.
  • Many homeowners choose to create a self-contained guest bedroom complete with en-suite facilities, perfect for visiting family or friends.
  • Families often opt for an open-plan living room and dining space to extend their current living areas, creating a light and airy space that flows naturally from the existing house.
  • Growing families frequently choose to create a children’s playroom with built-in storage solutions, giving children their own space while keeping the main house tidy.

Whatever your plans for your double garage conversion, your new space will be a versatile living area which can change throughout the years as your home life evolves.

What is involved in a garage conversion?

A full garage conversion requires various elements to create a habitable space; structural work such as reinforcing existing foundations, comprehensive insulation and damp-proofing are crucial to ensure your new space remains comfortable year-round.

New windows and doors are essential for natural light and access, while professional plastering and decorating will ensure a high-quality finish. Electrical and plumbing installations (including new circuits, lighting, and any necessary water connections) are also necessary for a well-functioning space.

Understanding extension costs: garage conversion price

The garage conversion cost varies depending on several factors. Factors that influence the final price of your garage conversion include the complexity and size of the conversion as well as windows, doors and internal finishes. A single garage conversion will cost less than a double garage conversion, as the material costs and labour costs will be slightly cheaper.

Additionally, many homeowners choose to include additional features that can impact the overall cost but add significant value to the finished space. Luxury additions such as underfloor heating can provide efficient warmth throughout the room. A fully fitted bathroom might be essential for a guest suite or gym conversion.

Planning and legal requirements

While most garage conversions fall under permitted development rights, meaning you won’t need full planning permission, it’s crucial to understand the legal requirements. Building regulations approval is essential, and your conversion must meet current standards for insulation, ventilation, fire safety, and structural stability.

If your property is in a conservation area or your garage is detached, additional planning considerations may apply. At Tyneside, we can handle all elements of your garage conversions, including assisting with planning applications and ensuring your space is up to current Building Regulations.

Benefits of converting your double garage

A well-executed garage conversion can increase the value of your property by up to 10-15%, making it a sound financial investment. The process is typically more cost-effective than moving house or building a traditional extension, with significantly less disruption to your daily life. Most conversion work can be completed within 4-8 weeks, and since the work takes place in an existing structure, it’s less affected by weather conditions than new-build extensions.

The transformation also offers practical advantages beyond the financial benefits. You’ll gain valuable living space without sacrificing any garden area, and the conversion can be designed to complement your existing home perfectly. By repurposing an underutilised space, you’re also improving your property’s energy efficiency, as converted garages typically have better insulation than their original form.
