Our Loft Conversion Process
Turning your attic into something actually usable—a bedroom, an office, whatever—is pretty exciting. But honestly? The whole planning, building, and design side of things can feel like a total headache. So we've dialed in a process. It's structured, it's clear, and it keeps your conversion on track, on budget, and looking good. No nasty surprises. Here's how it goes, from that first look-see to the moment you get the keys back.
Step 1: The Initial Consultation and Feasibility Survey
This bit matters more than anything. We don't do guesswork. A senior surveyor comes to your place, pokes around the roof structure, checks the head height, figures out where the stairs might go. Party wall stuff? Local council rules? Conservation area nonsense? We look at all of it. That on-site visit means we can give you a proper, fixed price—not some wishy-washy estimate that changes later.
Step 2: Design, Planning, and Permitted Development
Once you're happy with what's possible, our design crew gets to work on detailed drawings. We deal with the whole planning mess for you. Most of the time, a loft conversion falls under Permitted Development, so you skip the full planning permission nightmare. But we double-check with the council anyway—because some areas are tricky. We also handle the Building Regulations application. That's not optional, by the way. It's for your own safety.
Step 3: The Structural Build (The Core Process)
This is where the magic—and the noise—happens. We break it into four bits:
- Preparation and Scaffolding: Scaffold goes up, property gets protected. Anything in the way gets covered up.
- Steelwork and Roof Alteration: Steel beams go in to hold the new floor up. The roof gets cut into, and the dormer or roof lights get fitted.
- Floor Joists and Staircase: New floor joists go down, and the staircase gets cut in. That's your access point sorted.
- Plastering and First Fix: Insulation, plasterboard, skim coat. Then the first round of electrics and plumbing gets run through.
Step 4: Second Fix and Finishing
Now it starts looking like a room. We put in all the sockets, switches, and light fittings. Radiators go on, plumbing gets connected. Then the fun stuff—skirting boards, architraves, any custom joinery like wardrobes or storage. Painting and flooring? Done to what you asked for.
Step 5: Final Inspection and Handover
Before you move in, a Building Control officer comes to check everything. We do a walkthrough with you—a snagging list, basically—to make sure every little detail is spot on. You get a completion certificate and a warranty. Then we clean the place top to bottom. Done.
Frequently Asked Questions
How long does a typical loft conversion take?
A standard dormer or roof light job? Usually 4 to 6 weeks from when the structural build starts. Something more complex, like a mansard, can stretch to 8 or 10 weeks. We'll give you a timeline at the quote stage.
Do I need planning permission for a loft conversion?
Most are Permitted Development, so no full planning permission needed. But there are limits on volume, roof height, and materials. If you're in a conservation area or a listed building, you'll probably need permission. We handle all that legal stuff.
Will my loft conversion add value to my home?
Yeah, usually a good chunk. Think 15% to 20% on the property's value. It's one of the best ways to add space without moving house.
What is the difference between a dormer and a roof light conversion?
A roof light conversion is windows flush with the roof. Cheaper, but you don't get much headroom or floor space. A dormer sticks out vertically—like a box—and gives you way more room and headroom. Costs more, but you get a lot more.
Cost Breakdown: What to Expect

| Roof Alteration (Dormer) | £5,000 - £15,000 | Includes new roof, tiles, and flashing. |
| Electrics and Plumbing | £2,000 - £5,000 | Varies by number of sockets and radiators. |
| Plastering and Decorating | £2,000 - £4,000 | Includes materials and labour. |
| Staircase Installation | £1,500 - £4,000 | Depends on design (spiral vs. straight). |
| Total (Basic Dormer) | £40,000 - £60,000 | Excludes VAT and planning fees. |
Your Pre-Conversion Checklist
- Check Head Height: You need at least 2.2m (7ft 2in) of headroom in the middle of the room.
- Confirm Access: Make sure there's space for a new staircase without destroying the room below.
- Review Party Wall: Sharing a wall with a neighbor? Might need a Party Wall Agreement.
- Budget for Contingencies: Put aside 10-15% for stuff you didn't see coming.
- Plan for Disruption: It gets dusty and noisy. Seriously consider being out during the steelwork phase—at least a week.
Expert Insight: The Most Common Mistake
"Hands down, the biggest screw-up homeowners make is trying to cheap out on the staircase. A narrow, steep staircase kills the whole conversion. You need something at least 900mm wide with a decent pitch. That staircase is the key to whether the new room actually works or not." — Our Senior Project Manager
