Loft Conversion- 28 Dec 2023
Aviraj construction was hired by us to do a loft conversion (to include bedroom & bathroom) and also to refurbish the rest of house plastering, kitchen installation, bathroom installation, electrics, central heating/boiler and plumbing. Firstly I was impressed by how punctual they were and turned up at the agreed time at the first meeting to price the project. This was unlike other builders who either “forgot” or turned up late. The work was completed to a good standard and at no stage did Aviraj construction try and charge more than what was contractually agreed. Furthermore they were happy to fix any issues identified during the project. They were hard working, reliable and got on with the work without requiring supervision. I’ll definitely use them again on our next project! Thanks Guys appreciate all your hard work in getting the project completed.

Bathroom Fitting- 7 Jun 2026
Excellent service and outstanding workmanship! I recently had my bathroom renovated by this company and I couldn't be happier with the results. From start to finish, they were absolutely professional in every way. The quality of their work is truly perfect - they paid such close attention to detail and did an amazing job with everything. What's more, the price they quoted me was very reasonable and they stuck to it without any hidden costs or surprises. The whole process was smooth, efficient and stress-free. I would highly recommend them to anyone looking for building services - they really are top class and provide excellent value for money. Thank you for such a fantastic job! To Abdullah and his team.

We recently had our 3-bedroom house renovated, along with a new rear extension build and a garage conversion, and I couldn't be happier with the results. The team demonstrated exceptional craftsmanship and attention to detail throughout the project. From the initial consultation to the final handover, they were professional, reliable, and transparent about costs and timelines. The renovation completely transformed our home, enhancing both its functionality and aesthetics. The rear extension seamlessly integrates with the existing structure, creating a spacious and light-filled living area, while the garage conversion provides a versatile space we can now use as an office. The team was approachable, accommodating any changes we requested during the build, and always left the site clean and organized at the end of each day. I was particularly impressed with their ability to stay on schedule despite some challenging weather conditions. If you're looking for a dependable team that delivers quality work, I highly recommend Blueprint.

Loft Conversion- 27 Sep 2020
I met Jay for the first time on mybuilder.com; my job, roof extension received a huge interest; Jay was one of the first that came to discuss and he had one of the best quotes; although we discovered in the last second that the structural calculations were different from what actually the structure is, he was not afraid to get involved, and we worked along the engineer all the way through; his attitude and his team attitude was professional from day 1 until the end; the team came every day at the same hour and they were working really hard; in fact after just 1 day, the old roof was off, new structure was on with a rain proof cover; this thing told me from day 1 how professional and hard working they are and confirmed me that he was the right choice; the extension was done in half time just as a confirmation of above; they accommodated all my requests (like fitting air con pipes); the end result was great, or even better than expected; I truly recommend him and would certainly work with him in future projects.

Restoration & Refurbishment- 29 Mar 2018
A pleasure to deal with . Agim and his team worked hard to a very good standard.They often worked later than i would expect so that they were ready to move onto the next stage of the job the following day. Agim was very knowledgeable of all building regulations and was ready to offer me solutions when they were needed. All his team were courteous , polite and also knowledgeable. This was the first time I have used A&B but I would have no hesitation of using them again and recommending them to others.

The job was a complete refurbishment of a one bed flat, including rewiring and re-plumbing. We would recommend Al and his team without any hesitation. From the very beginning and all the way to completion, we felt very lucky and fortunate to hire them. We found them to be very hardworking, conscientious and professional. The job was a difficult and complex one, but the team still completed within time and within budget. Al's advice made the whole process easier and we found him to be very trustworthy and honest. The end result was better than we originally hoped for and was done to a high standard.

Loft Conversion- 18 Feb 2024
I wanted to express my gratitude for the exceptional work done by Cool Dudes Construction on my loft and bungalow conversion project. Despite an initial estimate of 12 wks, it was completed to a high standard within 15 wks, with only a minimal 3-wk delay due to 3rd parties (window suppliers) and the holiday season. A complex project. Full rebuild of bungalow, which included hip to gable conversion, rear loft dormer, stair, ground floor extension and full ground floor rennovations (1st & 2nd fix). Mandeep and Balwinder tackled a complex design that involved the integration of steel beams and pillars. They coordinated with various suppliers and also helped me to order skylights, windows, and doors, ensuring timely delivery and installation to keep the project on track. Team always showed professionalism, ensuring that they were always punctual, tidy, and respectful. Commitment to completing the project on time was evident, they maintained open communication throughout. One +ve aspect was their willingness to work with a private building control company that i hired, which ensured compliance with regulations. Another +ve aspect of working with them was clear payment milestones in the agreement. Payment was made on completion of milestones, which provided transparency and reassurance throughout the project. Extremely satisfied with the build and would not hesitate to recommend Cool Dudes Construction to others seeking reliable and efficient building services.

Extensions- 15 Oct 2020
DPS were superb from start to finish. They were hired to build a single storey rear extension in North London including a new kitchen and bathroom fit. I met Ralph on site along with a number of other builders, Ralph was highly knowledgeable and clearly explained what was required with practical solutions. DPS clearly scoped out the timeline and cost for each stage of the build and kept to this. They completed several agreed extras throughout the job. Communication with Ralph and the whole DPS team was first class throughout. I own a number of rental properties and can comfortably say DPS are the best builders I've dealt with, I cannot recommend them highly enough, they will be my first port of call for future work.

Loft Conversion- 16 Aug 2019
Hired Xhmi after shortlisting 5 quotes. Xhmi was not the cheapest but he showed the most interest to understand what I wanted to do & what would be possible given the size & configuration of my loft. He examined the drawings thoroughly & pointed out errors/inconsistencies in the plans. He provided a detailed quote after reaching agreement on what would be my cost vs his (tiling his - tiles mine). He started the job when he said he would. His team came everyday, worked all day & cleaned up everyday. Materials were ordered in a timely fashion to ensure that work didn't stall & the job kept moving along. Scheduled meetings with inspectors always went well with approval to move on to the next stages. Xhimi was always thinking ahead & often came up with suggestions to improve the design (for example adding a skylight or reconfiguring the ensuite bathroom). Adding a loft is a big project requiring a significant outlay of money. Hiring a stranger from a website was very scary particularly because I am not currently based in the UK & working abroad. Xhmi recognized this & sent pictures regularly, called me weekly (daily sometimes during crucial phases). My husband is a builder and was skeptical about starting this project while abroad. When we came for a site visit, he was so impressed with the quality of Xhmi's work & attention to detail that we hired him for other work. Xhmi takes pride in what he does, charges reasonable rates & I most definitely recommend him.

RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.

Latest review:
I received planning permission for a 3m extension, garage conversion and garden office with a toilet/shower and the architect recommended Timall. We of course carried out all our due diligence before selecting Timall as our builder. I received around 8 final quotes from various legal and reputable builders, and gratefully we chose Timall after checking their previous projects. Timall renovated my townhouse, stripped to brick, repartitioned to be more functional for my family, moved bathrooms, new kitchen etc. The council building control said we needed piling for the 3m extension, and Timall were fantastic to change their plans to carry out other internal work whilst a piling specialist was called in, who Timall also liaised with. The garden office, 3m extension and garage conversion all went well. Parminder the director was very hands-on during the project daily, with his builders on-site daily, honest in his advice, and very experienced in his knowledge of the building industry.

Questions to ask local loft conversion companies in Stanmore

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Stanmore?

A local loft conversion company in Stanmore will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Stanmore should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Stanmore loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Stanmore

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Stanmore before agreeing to start the work.

Do I need planning permission for a loft conversion in Stanmore?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Stanmore loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Stanmore loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
