Overview
What you need to know about loft conversions.
A loft conversion is the smartest space-creation project most Stockport homeowners will ever undertake. You already own the cubic metres — they're sitting empty above your head. The job is to convert them into habitable, regulation-compliant, beautifully finished living space without disrupting the rest of the house.
What it is
We carry out every common conversion type: rear dormer, hip-to-gable, L-shaped dormer, mansard and Velux/rooflight conversions. Every job includes structural steels and floor joists, insulation to current Part L, fire-rated staircase, electrics, plumbing for en-suites, plastering and full decoration.
Who it's for
Growing families needing a fourth or fifth bedroom, owners of 1930s semis in Cheadle and Bramhall with high pitched roofs, parents creating a teenage retreat, and remote workers wanting a dedicated office away from family life.
When you need it
When you've run out of bedrooms, when stamp duty makes moving uneconomical, or when you simply want the home you've already invested in to work harder for the next decade.
Why a specialist
Lofts involve structural work (new floor, steels, dormer cheeks), Building Regs sign-off (fire escape, insulation, stair protection) and roofing detail. A specialist who has built dozens of conversions on local property types will spot in five minutes what a generalist will miss for months.
The Real Risk
What happens when this goes wrong.
The cheapest loft conversion is almost always the most expensive in the long run. Here's why.
Risks of cutting corners
- Inadequate floor structure causing bounce, deflection and cracked ceilings in the rooms below.
- Failed Building Regs inspections on fire compartmentation — often only spotted at sale time during legal searches.
- Cold and condensation from inadequate insulation or missing breather membranes.
- Leaking dormer cheeks where flashing detail has been rushed.
- Stair designs that fail Part K head-height requirements, forcing expensive re-work.
Common homeowner mistakes
- Hiring a builder who doesn't routinely engage a structural engineer.
- Skipping Building Control to save a few hundred pounds and discovering at sale that the loft is legally still 'storage'.
- Specifying small dormers to dodge planning, then losing usable head height in the finished room.
- Choosing the staircase position last, instead of designing the whole house flow around it first.
- Forgetting to upgrade the boiler — leaving the new en-suite running cold.
Our Process
How we deliver, step by step.
Free Site Survey
Lewis attends in person to measure, assess constraints and understand what you actually want — not what's easiest for us to sell.
Design & Fixed Quote
Once we've fully scoped the work on site, you receive an itemised, fixed-price quotation with drawings or specification sheets where required. Larger projects take longer to price properly — never a vague allowance.
Planning & Approvals
We handle planning applications, building regulations, party-wall notices and structural drawings end-to-end.
Build Phase
One accountable team on site, daily progress updates, protected work areas and a tidy site every evening.
Sign-Off & Guarantee
Full walk-through, snagging completed before invoice, and your personally backed workmanship — Lewis returns to put right anything that isn't right issued on handover.

Benefits
Why homeowners choose Greenbank.
Adds ~20% to home value
Independent estate agent data shows a well-built loft conversion typically adds 15–22% to a Stockport property's value.
No loss of garden
Unlike an extension, a loft uses space you already have — the garden, driveway and footprint stay intact.
Minimal disruption
Most works happen above the existing ceiling. We use scaffold-mounted hoists to keep mess out of the house.
Building Regs certificate
Every conversion is fully signed off — protecting your property's legal status and resale value.
Energy-efficient by design
Modern insulation in the new walls and roof typically improves the whole home's thermal performance.
Workmanship we stand behind

Technical Detail
The detail that separates a 30-year job from a 5-year one.
Stockport's housing stock — 1930s semis, Edwardian terraces, post-war detached homes — suits four core conversion types. Choosing the right one is the difference between a gimmick and a transformation.
Conversion types we specialise in
- Velux/rooflight conversions — cheapest option, suitable where existing head height already exceeds 2.2m. No external alteration.
- Rear dormer conversions — the workhorse of Stockport semis. Adds full standing head height and significant floor area.
- Hip-to-gable conversions — for detached and semi-detached properties with hipped roofs. Squares off the roof to maximise interior volume.
- L-shaped dormer — combined rear and side dormer, ideal for Edwardian terraces with a rear outrigger.
- Mansard conversions — the most extensive, replacing the entire rear roof slope. Common in conservation areas where dormers are restricted.
Structural design
Every conversion begins with a structural engineer's calculations. New floor joists are typically 220mm or 250mm engineered I-joists or solid timber, supported on steel beams running between party walls or new pad-stones. Existing ceiling joists are NEVER relied upon — they're sized for ceiling loads only, not floor loads.
Insulation and ventilation
We insulate to a U-value of 0.15 W/m²K or better — significantly outperforming the 0.18 minimum. Warm-roof construction (insulation between and over rafters) prevents the cold spots and condensation common in older conversions. Mechanical extract ventilation is fitted to en-suites and a passive vent strategy maintains air quality throughout.
Staircase and fire safety
Stair design is the single biggest factor in how a loft conversion feels. We design the staircase first, the rooms second. All conversions to a third storey require a 30-minute fire-protected escape route from loft to final exit — we upgrade existing doors with intumescent strips and smoke seals, fit interlinked mains-powered smoke alarms, and use fire-rated plasterboard throughout the new construction.
Planning permission
Most rear dormer and hip-to-gable conversions in Stockport fall under Permitted Development, subject to volume limits (40m³ for terraces, 50m³ for semis and detached). Conservation areas (parts of Bramhall and Hale) require full planning permission. We assess this for free at survey stage.
