From the first stage of planning right through to the last stage of the build, they were incredible. The lead designer was responsive and thoughtful when dealing with any requests made for inclusion into the design. The follow up by the appointed project manager gave me incredible piece of mind. I can't recommend these guys highly enough. Once we heard the news about potential UK lockdown in a week time, all builders were working around the clock 12 hours a day, so now at least we have a massive and fabulous extension we can enjoy during this grim time. We are very thankful. More...

They were professional and informative right from the first meeting through to completion of our loft and rear extension. Tom was constantly updating us on the progress and always was there to answer our questions . The Quote was crystal clear with full breakdown. Any extra works were competitively priced, discussed in details and always needed our written confirmation beforehand. I felt like everybody was on the same page throughout the project. Would definitely recommend London House Extension. More...

Very happy with our kitchen extension. Professional approach throughout the project. We had a small unfortunate damage on site but all was covered by their insurance, which further boosted my confidence in their work ethic and word. All the best and thanks again

Polite and hardworking team. They are like Aston Martin among other cars if you compare it to builders. Relatively complex project was a cake for them. Very happy.

Our house was refurbished and extended in 2016. It took a bit longer than expected but we requested a lot of extra work so can't really fault them. Everything was fairly smooth, all boxes marked. We would use them again. More...

I was invited to this website by Tom to repost my review.
They build my extension and loft 2 years ago. We are very happy to this day. Overtime we had few cracks and socket problem but all was rectified under guarantee. More...

Super polite, always on time. Our extension was standing after just 10 weeks. Tomas who managed the project was very proactive and dealt with local authority like a champ.

Q&A

If there is 2,2 m between roof ridge and floor joists then usually you can convert your loft into habitable area. In most cases you will need planing permission.

Generally the building process can take between 10 to 12 weeks. You must allow additional month before start to deal with local authorities and produce all relevant documents. Please keep in mind some advanced loft conversions might take even 18 months+.

Loft Conversion Schedule:

1. Client Startup Meeting
2. Site Preparation (Scaffolding, Safety, protections, utilities)
3. Deliver and Store Materials onsite
4. Install steels and floor joists
5. Install Opening structure of loft shell
6. Installation of stairs/ windows
7. Make 1st fix Electrics and Plumbing
8. Install the insulation
9. Cover the structure/ Roofing
10. Plasterboarding
11. Plastering the space
12. Make 2nd fix of plumbing and electric
13. Make 2nd fix of carpentry
14. Snagging Process
15. Remove scaffolds
16. Completion

Seeing how the structure is slowly transforming into beautiful habitable area, documenting all so I can inspire future clients.
We also enjoy challenges by accepting unusual projects so we can get even more experience.

It was just a progressive career. Me and my colleagues started from bathroom fittings in 2007, then into kitchen fitting in 2008. Between 2008 and and 2011 we were getting enquiries from our bathroom/kitchen customers about lofts and extensions. We became proficient in this area over the years and expanded our contacts. Finally in 2012 we decided to form a company solely focused on extensions and lofts.
