The overall experience and result was in nothing short of impressive . Lokesh and his team completed the loft and bathroom to a high spec and work consistently , mainly focused on finishing, detail, and safety aspects of the Contruction/renovation . They have always been available for consultations to go through any concerns or issues. LNB’s recommendations for fitted wardrobes, windows , Bathroom supplies etc were extremely helpful.

Extensions- 18 Oct 2017
I asked Prohaus to undertake a ground floor side return and rear extension as part of the refurbishment of my flat in Putney. I have used many builders before on development projects but was especially impressed with Naz and his team on this build. It was the first time I used them and won’t be the last. Naz was great to work with, the whole build went smoothly and he always had a positive attitude and solution to any unexpected issue. The build came in on time and budget which was very impressive in itself. All in all I would highly recommend him.

Kitchen Fitting- 9 Aug 2026
Andy was brilliant from start to finish. Friendly, professional, very knowledgeable and willing to offer advice (but also happy to do it the customers way!). We had a large kitchen fitted with appliances and there were the usual “adjustments” off plan required -Andy did them without making a fuss. I would happily recommend Andy to a friend for kitchen fitting.

Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

Extensions- 14 Nov 2019
Bogdan himself is extremely knowledgable and his years of experience in industry is clear to see, which makes choosing him great value for money. Before and during the project he offered solutions that we hadn't considered and the would in fact save us money and be of benefit to us in the future. His team is punctual, reliable, diligent, speedy and clean! They take pride in their work which has led to a highly satisfactory work in the final build. Bogdan also has great connections to third parties (e.g. to flooring and curtains/blinds providers) which is very valuable, especially when trying to coordinate different aspects and timings of a full house redecoration. His quotes and payment structures are fair, clear and concise which is also very helpful. His communication is excellent too. All in all, Bogdan's great work took away a huge amount of stress during these projects. I would highly recommend Bogdan and his team for any prospective works someone is considering.

Extensions- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

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.

Questions to ask local loft conversion companies in Cobham

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 Cobham?

A local loft conversion company in Cobham 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 Cobham 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 Cobham 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 Cobham

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 Cobham before agreeing to start the work.

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

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