Use Your Space Guide To Loft Conversion Costs In Knowle
Looking to add space to your Knowle home without the hassle of moving? Use Your Space specialises in loft conversions throughout Knowle and the wider Solihull area, and we're seeing homeowners invest anywhere from £48,000 to £90,000 on quality conversions in 2025. Here's what you need to know about costs.
What's the Going Rate?
Knowle's a premium area, and that shows in the quality people expect. Most conversions we do here fall into these brackets:
Velux conversions start at £38,000-£52,000. These are the simplest type - adding skylights without changing your roofline. Great if you've already got the headroom.
Dormer conversions are what most Knowle homeowners choose. They cost £52,000-£75,000 and work beautifully on the Edwardian and 1930s properties you see throughout the village. You get proper standing space and a decent-sized room.
L-shaped dormers run £65,000-£90,000. Popular on detached houses around the village centre because they maximise every inch of available space.
What Affects the Final Price?
Your Property Type
Knowle has gorgeous period properties - Victorian villas, Arts and Crafts houses, characterful older homes. These often need more careful structural work than newer builds. We make sure everything's done sympathetically whilst meeting current building regs.
Staircase Installation
Every conversion needs a new staircase. Budget £4,000-£9,000 depending on where it goes and what style you want. We'll look at your landing space and recommend the best solution.
En-Suite Bathrooms
Loads of our Knowle clients add an en-suite when they convert. It makes sense if you're creating a master bedroom suite. Factor in £10,000-£16,000 for a quality bathroom.
Structural Work
Older properties sometimes need steel beams to support the new floor structure. This isn't optional - it's about safety and building regs compliance. Usually adds £3,000-£8,000.
Will It Add Value?
Knowle properties command strong prices. A professional conversion typically adds 15-20% to your value, often covering your costs and then some.
Quick example: £550,000 house + 20% = £110,000 increase. Your conversion costs £60,000-£70,000. You're £40,000-£50,000 up, plus you've gained usable space.
Planning Permission in Knowle
Most conversions don't need planning permission - they fall under permitted development rights. But watch out for:
- Conservation area restrictions (parts of the village have these)
- Article 4 directions that limit permitted development
- Front-facing dormers (these usually need permission)
We know Solihull Council's planning requirements inside out. We'll tell you upfront what you need.
Timeline
Expect 8-12 weeks depending on complexity:
- Scaffolding and prep: 1-2 weeks
- Main structural work: 3-5 weeks
- Electrics and plumbing: 1-2 weeks
- Finishing touches: 2-3 weeks
Most work happens in the loft space, so you can stay in your home throughout.
Is Your House Suitable?
Three things to check first:
Head Height
Need 2.3 metres minimum from floor to roof peak. Less than that and it won't work without major (expensive) changes.
Roof Structure
Traditional cut roofs are straightforward. Modern truss roofs need the trusses removing and replacing, which costs more.
Staircase Space
Where will it fit? You need proper headroom on the stairs themselves and space on your landing.
The good news? Most pre-1960s Knowle properties are perfect for conversion. Solid construction, decent roof space, traditional structure.
Other Costs to Consider
Don't forget:
- Building regulations approval (£500-£1,500)
- Party wall agreements if you're semi-detached (£1,000-£2,000)
- Architect or structural engineer fees if needed
- Decorating and furnishing your new space
