A loft conversion is one of the fastest ways to add a bedroom, office, or en-suite without moving. Most Milton Keynes homes can be converted, but the best approach depends on your roof type, head height, and how you want to use the space.
Typical budgets are £25,000–£50,000 depending on specification. The quickest way to get an accurate figure is a site visit so we can assess structure, access, staircase position, and finish level.
Most customers want the honest answer: “How long will I be living with building work?” Here’s a realistic outline for a standard loft conversion:
We keep you updated at each stage so you know what’s happening next and when rooms will be usable again.
Big projects only run smoothly when the basics are done properly. Our process is designed to reduce delays, surprises and “hidden extras”.
The best loft conversions feel like part of the house — not a “converted attic”. The layout should work with your daily routine, storage needs, and the rest of your floor plan. These are popular layouts we build across Milton Keynes and nearby towns:
A classic high-value option: bedroom at the centre (best head height), en-suite tucked into a dormer or behind the stair bulkhead, and built-in wardrobes along the eaves. Great for families who want the first-floor bedrooms back for kids.
If you’re hybrid working, a compact desk space with proper lighting and sockets is a game changer. We can design integrated storage so the room stays tidy.
Some roofs allow two rooms (for example: a guest room + hobby room). This needs smart stair placement and careful planning around head height, but it can work in the right property.
We’ll recommend the layout that gives the best combination of usable floor space, natural light and resale value.
A loft conversion shouldn’t feel “hot in summer, freezing in winter”. The comfort comes down to insulation, ventilation and smart heating. We build the room so it’s comfortable year-round — not just on completion day.
Good insulation keeps energy bills under control and reduces outside noise. Ventilation is just as important, especially for en-suites, because trapped moisture leads to mould and damage. We plan these details early so you don’t pay twice later.
We’ll advise on radiators vs electric options, socket positions, lighting zones and any future-proofing you want (like extra data points for office setups). The goal is a room that works properly from day one.
Built-in storage along the eaves is where loft conversions win. We can add access doors, shelving and wardrobe runs so the space stays tidy and usable. Finally, we finish with clean joinery, tidy paintwork and snagging — the details your guests notice immediately.
The staircase is usually the make-or-break detail. A loft conversion can only be classed as proper living space with safe access, and the stair position affects your first-floor layout and the overall feel of the house.
Most households stay in the property while the loft is converted. Early work is mainly in the roof space, so disruption is lower than a full rear extension. The noisiest stages are structural work and when the new staircase is installed. We keep the site tidy, protect key walkways and explain what to expect each week.
If you have kids, pets, or shift work, tell us — we can plan noisy tasks at sensible times where possible.
Two loft conversions can look similar online but cost very different amounts in real life. Here are the biggest drivers of your quote:
As a quick guide, a simple conversion may start from £25,000+, a dormer with premium finishes may land in the £40,000–£60,000 range. The right number depends on your exact roof and finish choices — that’s why a site survey matters.
Many loft conversions fall under permitted development, but that doesn’t mean “no rules”. The design still needs to meet building regulations for structure, insulation, fire safety, electrics, ventilation and the new staircase. We’ll tell you early if your property is likely to need planning approval (for example: large dormers on the front elevation, flats/maisonettes, listed buildings, or certain estates with restrictions).
If you’re not sure what you need, don’t guess — we’ll walk you through the right route on the first call.
We keep the work tidy and predictable with a clear plan, daily progress updates where needed, and a written scope so nothing “mysteriously appears” on the invoice later.
How long does a loft conversion take?
Most projects run 6–10 weeks depending on complexity.
Do I need planning permission?
Some loft conversions fall under permitted development. We’ll advise based on your property and design.
Will you handle electrics and plumbing?
Yes — we can manage the full job, including first/second fix, and coordinate specialist work where required.
Can you do a loft office?
Yes — we’ll focus on insulation, sound control, sockets/data points, and lighting to make it practical.
Transparent pricing with realistic timelines. No vague “estimate” that turns into a shock bill later.
Based around Milton Keynes with a 30-mile radius. Faster site visits, faster progress, better communication.
