Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry
Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

What can a local loft conversion specialist help me with?
Expanding your home vertically is an incredible way to gain space, but the structural style you choose will dictate both the internal layout and the exterior appearance of your property. Rather than a one-size-fits-all approach, a local loft conversion specialist can help you select from the four primary architectural styles:
- Velux / roof light conversion: The least invasive option, this style keeps your existing roofline completely intact. Your specialist will install flush roof windows, reinforce the underlying floor joists, and add a permanent staircase, making it perfect for properties where ample head height already exists.
- Dormer loft conversion: This is the most common extension method across the UK. It involves building a flat-roofed, box-like structure out from the sloping roof slope, creating a vertical rear wall that maximizes usable internal floor space and provides generous standing headroom.
- Hip-to-gable conversion: Standard on semi-detached houses or detached bungalows, this style straightens an inwardly slanted side roof into a vertical brick wall (a gable). This structural shift drastically increases the internal volume of your attic space, creating plenty of room for an extra bedroom and an en-suite.
- Mansard loft conversion: The most premium option, a mansard conversion essentially creates an entire new storey by flattening the top of the roof and sloping the outer walls inward at a steep 72-degree angle. It offers maximum design flexibility but requires major structural remodeling.
A local loft specialist understands your regional building styles and property types, ensuring your roof receives the precise reinforcement and structural changes it needs.

How much does a loft conversion cost on average in the UK?
Budgeting for a vertical home expansion requires a realistic understanding of current construction, material, and structural engineering fees across the UK. On average, most homeowners can anticipate an investment ranging from £25,000 to £75,000+.
- Velux roof light styles: These are the most budget-friendly, typically averaging between £25,000 and £33,000 as they require minimal alterations to your roof structure.
- Dormer extensions: For a classic rear dormer setup, prices generally scale from £45,000 to £65,000 due to the added labor and materials needed to build the new vertical walls.
- Hip-to-gable and Mansard builds: Because these styles involve altering primary external brickwork and complex roofing lines, expect costs to land between £50,000 and £75,000+.
Other essential variables that will influence your final estimate include professional fees for architectural design drawings, structural calculations from a qualified engineer, scaffolding hire, and internal finishes like plumbing an en-suite.

Do I need formal planning permission to convert my loft space?
One of the biggest advantages of a loft conversion compared to a traditional ground-floor extension is that many projects fall neatly under Permitted Development (PD) rights. This means you can proceed without a lengthy local authority planning application, provided your design meets specific national criteria, such as not exceeding a volume allowance of 40 cubic metres for terraced houses or 50 cubic metres for detached and semi-detached homes.
However, your Permitted Development rights do not apply if your property is a listed building, sits within a designated conservation area, or if you plan to extend the roof height beyond the existing ridge line or alter the front elevation facing a highway. Even if your project qualifies for PD, it is highly recommended to have your builder apply for a Lawful Development Certificate to provide official proof of compliance when you sell your home in the future.
Other loft conversion FAQ's
Will my loft conversion need to pass UK Building Regulations?
Yes, all residential loft conversions must strictly comply with UK Building Regulations to legally guarantee structural safety and fire stability. A specialist will install heavy steel RSJs to safely support the weight of the new floor, as standard ceiling joists are not strong enough on their own. Inspectors will also check critical safety features, including proper thermal insulation, a mains-powered smoke alarm system, and a legally compliant, fire-resistant staircase escape route.
How long does a typical loft conversion take to build from start to finish?
A standard rooflight or dormer loft conversion usually takes between 4 to 6 weeks of active on-site construction to complete. The initial 2 to 3 weeks are structural and handled externally via scaffolding to minimise household disruption, while the remaining weeks focus on internal breakout, plumbing, electricals, and plastering. More complex projects, such as hip-to-gabled or full mansard installations, can extend the total build timeline to 8 to 10 weeks.
What structural factors will a specialist check before providing a quote?
Before drafting a quote, a specialist will conduct a physical survey to ensure your attic has a minimum usable head height of 2.2 metres from the bottom of the ridge timber to the top of the ceiling joists. They will also evaluate whether your home has a traditional cut roof with open rafters or a post-1970s fink trussed roof with W-shaped timber supports. While trussed roofs are completely convertible, they require more complex structural steel framing to replace the timber web safely, which impacts overall material and labor fees.
Whether you need a simple roof light upgrade or a major structural transformation, speak to a specialist today to receive a free loft conversion quote.

Had some work on our roof completed in May 2024. This was completed to a poor standard, which we only realised after problems. Michael did return to supposedly correct these issues. However, we still have a leak and parts of the flat roof are flaking off only a few months afterwards. Have tried numerous times to contact Michael with limited success. He is now completely avoiding contact either by phone or email and has failed to return and rectify the problems. Would not recommend or use again.
