Transforming a garage into a living space is becoming a popular option for UK homeowners looking to maximise their property. Whether you're after an extra bedroom, a home office, or a granny flat, converting your garage can be a cost-effective alternative to moving house. Here’s a detailed overview of what you can expect in terms of costs and the steps involved.

The cost of converting a garage varies significantly based on the size of the garage, the intended use of the space, and the quality of finishes. For a basic conversion—turning the garage into a functional room with minimal structural changes—costs typically range from £15,000 to £17,500. This usually includes insulating walls and floors, adding basic lighting and electrical outlets, and installing basic flooring and wall finishes. For a mid-range conversion that involves more extensive electrical work, plumbing, and higher-quality finishes, you can expect to pay between £17,500 and £25,000. This could cover the installation of windows or skylights, improved insulation and heating, mid-range flooring and wall finishes, and the addition of a basic bathroom if needed. A high-end conversion, which includes top-tier finishes and significant structural changes, can cost upwards of £25,000, potentially reaching £35,000 or more. This might include high-end insulation, heating, and ventilation systems, premium flooring, wall finishes, built-in furniture, and a full bathroom or kitchen installation.

Additional costs to consider include planning permission and building regulations. While many garage conversions fall under permitted development rights and don't require planning permission, it’s crucial to check with your local council. Building regulations approval is necessary to ensure the conversion meets safety and energy efficiency standards, with fees ranging from £200 to £500. If your garage requires significant structural changes, such as raising the floor level, reinforcing the ceiling, or adding windows, this can increase the overall cost. Hiring architects, designers, or structural engineers can help ensure your project meets all requirements and is finished to a high standard, with professional fees typically ranging from £500 to £2,000, depending on the scope of work.

The procedures for converting a garage involve several key steps. Begin with initial planning, deciding how you intend to use the space and whether you need additional plumbing, electrical work, or structural changes. Consult your local planning authority to determine if you need planning permission and apply for building regulations approval to ensure compliance with safety standards. Engage an architect or designer to draw up detailed plans and hire a structural engineer if major structural changes are needed. Clear out the garage and address any existing issues such as damp or structural weaknesses, ensuring the space is watertight and adequately ventilated. Depending on your plans, structural work may include raising the floor, adding insulation, installing windows, and reinforcing walls and ceilings. If required, add plumbing, heating, and electrical systems, which may involve connecting to existing systems or installing new ones. Once the structural work and utilities are in place, finish the interior with drywall, flooring, lighting, and any built-in furniture or fixtures. Finally, arrange for final inspections by building control to ensure the work complies with all regulations and obtain a completion certificate.

Converting a garage into a living space is a smart way to add value and functionality to your home. While costs can vary significantly based on the scope and quality of the conversion, careful planning and adherence to regulations can ensure a successful project. With the right approach, a garage conversion can provide a versatile and valuable addition to your home.
