Garage Conversions
A cold, cluttered garage can become everyday living space, giving your home more room without losing garden space or needing to move.
Why Choose SB Builders
Plans shaped around how you want the room to work.
Insulation and airflow considered before work begins.
Floors, access and daylight planned before fit out.
Electrics, plumbing and storage planned for daily use.
Conversion Types
The right garage conversion depends on what your home is missing now and how the extra space needs to support daily life.
Create more living space while keeping the roofline unchanged.
Improve flow when the garage already connects to the house.
Create a quieter office, gym or guest space away from the house.
Free up busy rooms with a workspace planned around daily use.
Move laundry, boots and storage out of the main living areas.
Add useful sleeping space when the house is starting to feel full.
The right checks make a garage conversion warmer, brighter and easier to use, with fewer awkward changes once the build begins.
Room Planning
Settle access, furniture, lighting and storage early, so the finished room works properly instead of feeling like leftover garage space.
Planning Permission
Permitted development may apply, but planning permission and building regulations depend on the property, changes and intended room use.
Floor And Fabric
Floor levels, insulation, ventilation, windows and doors should be planned before the room starts taking shape.
Electrics And Heating
Electrics, lighting, plumbing and heating work better when positions are agreed before desks, storage or utility layouts are built.
Garage Conversion Costs
Your quote depends on openings, insulation, services, room use and the level of work needed before it can be priced properly.

From the first consultation to the final result Sam and his team carried out exemplary work on our large house extension. We were especially impressed with the standard of brickwork in the build. Simon and Sam were happy to adapt and correct as different situations arose, without any hassle. The whole team were a pleasure to have in our home.Posted on Debbie GinnsTrustindex verifies that the original source of the review is Google.

Would highly recommend them .. brilliant from start to finish ! Thank youPosted on Suzi IrelandTrustindex verifies that the original source of the review is Google. Sam and his team recently completed a loft conversion for us, and we can’t recommend them enough. Where we had been let down by other professionals previously, SB construction went above and beyond to ensure that the build was able to go ahead. And wow what a transformation we couldn’t be happier. Not only the build itself is fantastic, but the family run feel and that personal touch made the whole build experience enjoyable.
