Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!

Bathroom Fitting- 18 Jan 2019
How can a tradesman have ALL those reviews and still retain a 100% positive feedback record? Surely some mistake? By being genuinely brilliant, that's how! Really nice guy, solution-orientated, flexible, extremely professional, very, very high standard of work; the kind of tradesperson you are happy to have in your home and to leave to just get on with it. If ever there were an issue or something which he did not feel he could do to the level required (i.e. the steam room installation), he would relate it to us clearly and suggest ways to resolve. It is honestly not possible to speak more highly of Catalin.

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.

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.

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 Swiss Cottage

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 Swiss Cottage?

A local loft conversion company in Swiss Cottage 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 Swiss Cottage 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 Swiss Cottage 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 Swiss Cottage

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 Swiss Cottage before agreeing to start the work.

Do I need planning permission for a loft conversion in Swiss Cottage?

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