Loft Conversion- 22 Aug 2025
I had Panesar Builders build a dormer extension garden room and a bedroom above the garage around two years ago. I deliberately waited before writing a review to be sure there were no hidden issues — and I can happily say everything has held up perfectly. Before choosing Panesar Builders, I researched and spoke with many builders. His quote came in at a fair, middle-ground price — not the cheapest, but not the most expensive either. I felt confident in my choice, and two years on I can say it was absolutely the right decision. The work was completed to a high standard, communication throughout the project was clear, and the whole process was smooth. Two years later, the extension is still solid, with no problems at all. It has completely transformed our home. I really appreciated the professionalism, reliability, and attention to detail shown. I would have no hesitation in recommending Panesar Builders to anyone looking for a trustworthy builder who delivers quality work that lasts.

Loft Conversion- 5 Dec 2018
Firstly the date of job posting and date of completing is all down to me not being ready with finances!! Secondly, and more importantly, GG Property were the most wonderful and professional bunch of lads you can hope to met. The work was done with such enthusiasm and to such a high level of detail. We could not be happier with the finished job. Thirdly, the great building work aside, GG Property were polite, happy, friendly, punctual and great communicators. All emails answered swiftly and with accurate information. No question was to silly and no concern (this was our first major building working) was to small to be addressed. Finally we are so pleased with work we are awaiting a quote for our bathroom and look forward to getting that job completed!! In short my experience with GG Property was nothing but top quality work and customer service. Any fears of the classic 'cowboy builder' could not be further from the truth; GG Property are a hard working truly lovely bunch and we would highly recommend them.

Extensions- 17 Aug 2026
I had a very poor experience with this contractor and would strongly advise potential customers to be cautious before paying substantial sums in advance. I paid £3,672 by bank transfer following an invoice for the supply of structural steelwork. There were significant delays and communication issues, and the steel was not supplied to me as agreed. After giving him opportunities and clear deadlines to resolve the situation, I terminated the agreement and had to make alternative arrangements to keep my project moving. Most concerningly, despite my requests, the £3,672 I paid has still not been refunded as of the date of this review, and I am now pursuing the matter formally. Based on my experience, I cannot recommend this contractor. I would advise anyone considering using his services to be extremely cautious about making advance payments. I will update this review if my £3,672 is returned.

Gengi did a great job on the new extension roof. The timberwork was completed to the highest standard and worked with the building inspector's expectations. He was knowledgeable and talked me through the various options and the pros and cons of each. He was on time, professional, hard-working, and exacting. I'm really pleased with the final result. Highly recommended!!

Loft Conversion- 6 Sep 2024
I recently worked with Ardit from AK Constructions and Developments on a double dormer loft conversion, which included creating two large bedrooms, a bathroom, and a utility room. I'm delighted with the results; the quality exceeded my expectations, and everyone who's visited has been impressed. Ardit's approach was professional and not pushy, unlike other builders. He provided references and even invited me to see a current project, which convinced me. Ardit was flexible, suggesting changes like moving the bathroom for better functionality, which turned out great. His team, including Edi and Vini, were polite, courteous, and always willing to help. The work finished ahead of schedule, and Ardit sourced excellent tradespeople, making the experience stress-free. I was so impressed that I also asked him to redo my kitchen, and I'm thrilled with the outcome. I highly recommend AK Constructions and Development.

Extensions- 8 Dec 2023
I recently had the pleasure of accepting Jagdeep on a substantial renovation project. Initially, I was a bit apprehensive as there were no existing reviews to gauge his work. However, after seeing some of his previous projects, I decided to take a leap of faith - and it turned out to be the best decision I've ever made. Jagdeep's approach to our project, which started merely as a rear extension and shower room, was nothing short of exceptional. His remarkable craftsmanship and attention to detail soon convinced me and my wife to extend the scope to a full renovation. Throughout the process, Jagdeep and his team displayed an extraordinary level of skill, professionalism, hard work as well as trust (very rare these days). No task was too challenging, and his willingness to prioritise our needs and provide thoughtful advice was truly comforting. It's rare to find a builder with such dedication and expertise. Jagdeep is undoubtedly one of the best builders I have encountered. My heartfelt thanks to Jagdeep and his team for their outstanding work. Rest assured, for any future projects, he will be the first person I call. Thank you, Jagdeep, for turning our vision into reality, which more than exceeded our expectations!

Questions to ask local loft conversion companies in Belvedere

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 Belvedere?

A local loft conversion company in Belvedere 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 Belvedere 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 Belvedere 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 Belvedere

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 Belvedere before agreeing to start the work.

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

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 Belvedere 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 Belvedere loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
