Short on space but happy with your street? Look up. Loft conversions in Birmingham are one of the simplest ways to add a bedroom, office or en-suite without moving house.
We work on homes across the city, from Victorian terraces in Moseley and Kings Heath to 1930s semis in Hall Green and Erdington. Every roof is different, so we assess yours before suggesting a design.
As loft conversion specialists in Birmingham, we handle the design, structural work, Building Regulations and the build. You deal with one team from survey to handover.

Converting a loft means cutting into your roof. You want a team that plans every step properly. Here’s how we work.
1. Design & Construction Coordination
Your drawings and your build come from the same team. Nothing gets lost between the designer and the site.
2. Structural Coordination
Most conversions need new steels or floor joists. We bring the engineer’s calculations straight into the build plan.
3. Defined Scope of Works
Before work starts, you’ll see exactly what’s included. Insulation, stairs, windows and finishes are all written down.
4. Professional Project Management
A project manager runs your site day to day. Trades arrive in the right order, so the job keeps moving.
5. Quality Control
We check the work at each stage, not just at the end. Issues are fixed while they’re still easy to reach.
6. Building Regulations
Fire safety, insulation, stairs and structure all need sign-off. We work with building control from the start.
7. Wider Renovation Capability
Planning a kitchen extension or new bathroom too? We can fold it into the same Birmingham project, with one team.
We talk through how you want to use the space, your budget and your timescale. No pressure, just honest advice.
We measure head height, check the roof structure and work out where a staircase could go in your Birmingham home.
We draw a layout that suits your roof shape. You will see where the bedroom, storage and any en-suite will sit.
We check whether permitted development applies. If it does not, we prepare an application to Birmingham City Council.
Structural calculations and Building Regulations drawings are prepared, covering steels, fire safety, insulation and stairs.
You receive a written scope and an itemised quote. Every element is listed, so you know exactly what you are paying for.
Work moves through structure, roofing, first fix, insulation, plastering and second fix. Much of the early work is done from the scaffold.
Your project manager checks each stage before the next begins. We hand over once everything matches the agreed scope.
1. Dormer Loft Conversions
A dormer pushes out from the roof slope to create full head height. It is the most popular choice for a dormer loft conversion in Birmingham.
2. Rear Dormer Conversions
Built on the back roof slope, a rear dormer adds plenty of floor space. Your street-facing roofline stays as it is.
3. Hip-to-Gable Loft Conversions
A good fit for the city’s 1930s semis. We rebuild the sloping side of the roof as a vertical gable, opening up the whole loft.
4. Rooflight / Velux-Style Loft Conversions
If your loft already has good head height, rooflights may be all you need. The roof shape stays the same and daylight pours in.
5. Mansard Loft Conversions
A mansard replaces the rear slope with a near-vertical wall. It can suit terraced streets, but it usually needs planning permission.
6. Bedroom Loft Conversions
Turn unused roof space into a proper double bedroom. It is often easier than finding a bigger house in the same area.
7. Master Bedroom Suites
Give yourself a quiet top-floor retreat. There is room for a bed, wardrobes and a dressing area, away from the busy rooms below.
8. Loft Conversions with En-Suites
We plan the plumbing and waste routes early. That way the shower sits where the head height works best.
9. Home Office Loft Conversions
A separate floor for work makes a real difference. Close the door at the end of the day and leave the laptop upstairs.
10. Loft Conversion and Renovation Projects
Updating more of the house? We can run your loft alongside a wider home renovation in Birmingham under one programme.
11. Loft Structural Alterations
New steels, stronger joists and altered roof timbers are designed by a structural engineer and installed by our team.
12. Staircase Installation
The staircase shapes the whole design. We position it to meet Building Regulations while losing as little space below as possible.
13. Roof Alterations and Strengthening
Older Birmingham roofs sometimes need extra support before conversion. We assess the timbers and strengthen them where needed.
Not always. Many lofts fall under permitted development. This allows up to 40 cubic metres of extra roof space on terraced homes and 50 on detached and semi-detached homes. Front-facing dormers, mansards and homes in conservation areas, such as parts of Moseley and Edgbaston, usually need permission from Birmingham City Council. We will confirm the right route for your property.
Yes. Turning a loft into a habitable room always needs Building Regulations approval. It covers structure, fire safety, insulation, ventilation and the staircase. We prepare the drawings and work with building control throughout.
It depends on the conversion type, the roof structure and your finishes. A rooflight conversion usually costs less than a dormer or hip-to-gable. We give you an itemised quote after a free survey, so you are working from real figures.
It can. Homes covered by the Bournville Village Trust Scheme of Management usually need the Trust’s consent for external alterations. That is on top of any council approvals. We will build this into the planning stage, so it does not hold up your start date.
If you live in a terrace or semi, you probably will. The Party Wall etc. Act 1996 applies when steels are set into a shared wall. You need to give your neighbours notice before work starts. We will explain the process and the timings involved.
Your next bedroom or office could already be sitting above your head.
As a loft conversion company in Birmingham, we take your project from the first survey to the final clean. That includes design, structural work, approvals and the build.
Need more room on the ground floor as well? Take a look at our home extensions in Birmingham. We also carry out loft conversions in nearby Solihull, Sutton Coldfield and Smethwick.
