"If you want to convert your garage to a habitable dwelling then you have to apply for change of use
So it will need building regulations approval
Got to take into account that services need to be run to garage, water, waste, eletrics ,
You dont need planning if your not changing the the size or shape"

"Embarking on a DIY garage conversion to create a two-bedroom accommodation is quite an ambitious and exciting project. It's crucial to approach this with a thorough understanding of both planning and building regulations in the UK. Let's break down the key points you need to consider:

Planning Permission: Firstly, check whether you need planning permission for your conversion. Generally, converting a detached garage into living space may require planning permission, especially if you are changing its use (from storage to residential). However, some conversions fall under permitted development rights, meaning they don't require planning permission as long as they meet certain conditions. It's best to check with your local planning authority to confirm this.
Building Regulations: Regardless of whether you need planning permission, your conversion will need to comply with building regulations. These regulations cover aspects like structural integrity, fire safety, insulation, damp proofing, ventilation, and electrical works. You'll need to submit either a full plans application or a building notice to your local council's building control department.
Design and Layout: Consider the layout and design of the two bedrooms and any additional features like bathrooms or a kitchenette. Think about natural light, ventilation, access, and how the space will be used.
Insulation and Damp Proofing: Garages are not typically built with the same level of insulation as residential buildings. You’ll need to upgrade the insulation to make the space habitable. Also, ensure adequate damp proofing is in place.
Electrical and Plumbing: If you’re adding a bathroom or kitchenette, plumbing will be a key consideration. Electrical wiring will also need to be planned, adhering to safety standards.
Heating and Ventilation: You’ll need an efficient heating system and good ventilation to prevent damp and condensation.
Professional Advice: While it's a DIY project, getting professional advice for certain aspects (like structural changes) is advisable. You might need to consult an architect, a structural engineer, or a building surveyor.
Notify Your Neighbours: If your property is semi-detached or terraced, you should notify your neighbours about your plans, particularly if the work falls under the Party Wall Act."

"You don't need planning permission or building regs for DIY garage conversion but the issue will come when it comes to selling your house. Your next buyer would need the building regs for this to class it as another 2 bedrooms for you to make a profit of your hard work"
