Restoration & Refurbishment- 17 Jul 2016
Valter was very impressive on his initial visit with some exciting ideas for the house improvements and we had no hesitation in choosing Happy Building above the other two building firms who quoted. Having signed off on the budget and scope of work, Valter's team of builders arrived. We were hugely impressed with the skill, experience and work ethic of the team; the fact that they arrived early each morning smiling underlined the "Happy Building" epithet; Jarek, the site foreman, had an especially cheery demeanour. The work involved stripping the walls back to bricks, removing walls, reinforcing foundations, plastering, extending the bathroom and removing one bedroom to create a large ensuite bedroom. The latter certainly would not have been done without Valter's vision and patience in explaining how it would look. We were able to deviate from the original plans without any problem which was very important in achieving the final look which we had desired. Valter was very careful in sticking to time and budgets which I had never experienced before with builders. The kitchen, bathroom, two bedrooms, living room and hallways were finished to the highest possible specification within our budget. There were one or two small features which, with hindsight, we would have improved such as door handles and shower fittings, however this was down to us not specifying exactly what we wanted. These are very minor details and a tiny part of the overall picture.

Carpentry- 14 May 2026
Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

We used Vector Living as they were recommended to us by a friend. We were looking for a company to do our fairly large extension and loft conversion. We were nervous about finding a reputable builder as we had heard horror stories in the past. However, from the very start Ash was highly professional and explained the whole process step by step and put us at ease. He provided us with various options we hadn’t considered with not only saved a bit of money but also time. We did encounter unforeseen issues but this is where Vector Living made the difference, they always found a workable option for us. The process of construction was also smooth, always on time and finished to a very high level. We are extremely happy with Vector Living and would highly recommend them. If we ever decide to do a build again will be using them.

Loft Conversion- 10 Feb 2026
We had a great experience working with BS Loft Conversions on our L-shaped dormer loft conversion. Anxhelo was friendly, approachable and professional from the initial quote through to completion. We made a few changes as the build progressed, and he was always open to discussing options and finding sensible solutions. We found the original quote fair, and the additional items we added were also priced fairly. Anxhelo was generous with his time in offering advice on different aspects of the build, which we really appreciated. The team – Anxhelo, Klaidi, Henry and Jimmy – were on site consistently, worked hard, and are clearly experienced at what they do. At the end of each day, and at the end of each stage of the project, the site was always left very clean and well organised. Before choosing BS Lofts, we spoke to previous clients and heard positive feedback, which gave us confidence. Having now worked with them ourselves, we’re happy to recommend them to friends and family.

The project lasted from July 2023 to Feb 2024 and comprised of: 1. Single story rear extension with new kitchen and underfloor heating 2. 75m2 patio 3. Internal reconfiguration including removal / installation of walls, new flooring, plumbing (including new boiler), new door frames, doors and skirting, redecoration, carpentry for cupboards 4. Ventilation of existing roof The team are both friendly and professional with Alin always on hand to manage any questions / situations as they arise. The work is clearly costed and every two weeks a valuation takes place to ensure transparency of work undertaken both in original scope and any extras. The quality of the build was excellent, something the building inspector commented on. Alin was recommended to me based on past work, and I in turn would highly recommend him.

My house was old and its condition was poor. Much were needed to be fix. The original kitchen layout were also inconvenience to my wife. I need to have all these changed under limited time. This builders have a team of specialists on almost every aspect. They gave me variety on the layout design and choose of materials. This saved me money, time and tons of trouble to find difference contractors. The after service and their respond time are very good too. I hope by sharing my happy experience can save your money and trouble to find a good contractor.

Groundwork & Foundations- 9 Oct 2017
Excellent work, and I'm very happy with my concrete plinth. The work was done on time and to schedule. All preparatory stuff was sorted, i.e. skip, license etc and after completion the site was left spotless. And all this for a very competitive price. Can't recommend these lovely guys highly enough and will certainly use them again.

Questions to ask local loft conversion companies in East Horsley

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 East Horsley?

A local loft conversion company in East Horsley 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 East Horsley 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 East Horsley 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 East Horsley

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 East Horsley before agreeing to start the work.

Do I need planning permission for a loft conversion in East Horsley?

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