Some recent testimonials from satisfied clients…

Loft conversion and ground floor extension 

Our project started at the same time as that of my neighbour, and I have been extremely glad that I followed their lead in choosing House Extension Wandsworth for our project.

The project comprised extending an existing loft space to form a new bedroom , structural work for a new sun lounge at ground floor level, and modified drainage relating to my neighbours extension.

The project was carried out while we remained in occupation, with the Wandsworth Team ensuring disturbance was kept to a minimum. Wandsworth were proactive from the outset, helping us confirm project scope and budget and managing the process from start to finish through building control procedures with all our requirements met and any problems quickly resolved to our complete satisfaction without delaying completion.

Their workmanship has been excellent, and the result is stunning.  I am happy to recommend them without reservation.  They will be our first choice for future building work.

60 square metre two storey side extension, vaulted ceilings incorporating existing loft space, structural work to existing


House Extension Wandsworth built for us a 2 storey extension to our home.  We chose Peter’s company over 3 others, because of his competitive pricing, strong history of delivering to a tight timeframe, and demonstrated ability to handle non-standard works.  With the project now complete, we are certain that we made the right choice – the work was completed on time and on budget, despite a number of external complications; Peter’s team managed changing structural specifications (no fault of House Extension Wandsworth, as we regrettably used our own structural engineer) as well as extreme weather conditions.  As well as being genuinely lovely people, the team of builders were incredibly efficient, and every day we were able to see progress that had been made.  They were able to handle everything they encountered with ease, bringing in specialists when necessary, which made a lot of difference especially on the work that involved the existing property, such as the roof, and the steel-work.  The accuracy of the work has made all of the second fix work much easier.

The way that House Extension Wandsworth charge made our lives easier, as all costs are broken down straightforwardly and spread across the duration of the project.  Bear this in mind when comparing quotes, as unfortunately not everyone works this way.

We are very happy with the finished build, and House Extension Wandsworth will be our first call for any future projects.

Peter and his team did our wrap-around extension in Clapham earlier this year and we couldn’t be happier. 100% reliable, knowledgeable and extremely high-quality work in line with the agreed budget. Don’t look any further if you are in need of an outstanding building company to complete your extension project in literally 30 days!

Peter’s team replaced a rather falling down conservatory with a nice new extension.  They also put in some king-sized meccano to open up the house a bit.

Cost increases and delays: The 30 day extension concept is great, we went over this for two reasons:

– the Building Control made us have bigger foundations (no moans from the team, they just got on with digging half way to Australia!)

– the doors were delayed, and so they built us a very nice patio while we were waiting.

Otherwise 100% on time and budget!

I used to enjoy the end of day conversations with Taras – they always ended “OK, no problem”.

Tidy and considerate.

I would recommend them to friends and would use them again.

Single story side & rear extension

We have been really happy with every stage of our project with Peter & Co.  The process was made so much easier by Peter, Neill, Taras, Emma and the guys on the ground, they are all very helpful and eager to make the whole thing as painless as possible.

Design, preparations, payments (the transparent and easy breakdowns by Emma are so helpful) and actual build all felt really straightforward.  A few hiccups in prep were met with easy solutions and welcome support.  Likewise, issues during the build were dealt with immediately and painlessly by Taras and the guys.

Before meeting Peter, we had felt that no-one had really listed to us or considered the project from our point of view – he absolutely did.

Peter is very open, straightforward and chatty which immediately made me feel less stupid than I had with other building and design professionals!

He talked us through how his company could help us achieve what we wanted, rather than telling us what we really should want!

We were able to get started in October 2018 and they really do build to shell in 30 (working) days.  The guys worked like trojans and were professional, tidy and respectful throughout.  We were also very pleased to hear on one Building Regs visit that the work was of a very high standard!

There’s a lot more to say than there is room for here but if you want a very good standard of build by a decent, honest, accommodating and competitively priced company, then look no further, these guys are great!

Highly recommended.

L-shaped mansard with roof terrace

House Extension Wandsworth led by Peter supported me in undertaking a 2 bedroom, 1 roof terrace loft extension.  All I can say is exceptionally positive messages for him and his team, they delivered on time, were competitive on price and flexible when changes arose throughout.

The team led by his project manager Taras were always punctual and had an eye for detail, which always meant that finish was to a top quality standard.  I have done numerous developments previously, however going forwards I will not be using another company, as I honestly haven’t had another team who’ve come close.  For this particular job I originally only had them scheduled to complete the first fix, however in the end I had them do the 2nd fix, whilst also helping to build built-in wardrobes and bookcases, all of which look as through they’ve been there for years .

The house now looks amazing and I would not hesitate to recommend Peter, given I work with people who are always there to answer questions and don’t shy away from a challenge.

Note: I did significant research against a number of companies, however Peter came in with not just a fair price, but was transparent around what was included.

2 storey side extension

I have had some experience in building so I can compare how they performed.  Peter Snelson is a very nice person, open and straightforward.  The project involved a large side extension and the most difficult part was a huge steel beam spanning some 7.2 metres and weighting 1.5 tonnes.  So I specifically looked for a company which would be able to do it.  Peter promised to complete the shell in 30 days.  The price was reasonable so we agreed.

I was very impressed by the team headed by Taras.  I could see from day one that they knew exactly what to do and that they had a clear plan.  The materials and tools arrived exactly when needed and they were never idle.  As it usually happens, there were some problems: the foundation had to be made much deeper because of some trees nearby, the amount of excavation and the number of containers were exceeded but they did manage to complete the main construction in 4 weeks.  The shell was  actually completed in 5 weeks but this was because of the additional works like a fireplace chimney and a bay window.  Still it was an excellent result.

As for the finance, I liked the clear system they have.  At the end of every week I received a statement with the detailed account of the expenses for wages, materials and skips.  They also provided a diagram showing the percentage of the up to date expense in relation to the agreed cost.

I would certainly recommend this company and will hire them again for the roof conversion.

Ground floor extension with piling

House Extensions Wandsworth built a 4m ground floor extension for our terraced house. I would recommend Peter and his team to anyone planning an extension.

The build team led by Taras were efficient and kept me up to date with any issues and decisions required. Peter and Emma from the office kept me well informed of progress and were easy to get hold of if I had any questions or concerns. The overall project was well organised.

There were some slight delays due to additional foundation work needed to be carried out by sub-contractor after a change in our engineers designs. Similarly, we had to wait a few weeks after the build was finished for the sliding doors to be fitted (in part due to the speed build was completed and circa 6 week lead in time for doors!). I’d recommend thinking about sliding/bi-fold doors as early as possible and discussing with Peter’s team early in process to avoid any delays.

Overall I was very pleased with the customer service that Peter and his team provided and how quickly they were able to complete the work. We were quoted a fixed price for the core work and any changes in scope were communicated to us in advance.”

Loft Conversion

Throughout the whole process, all the team, Peter, the builder Taras and his team and Emma in the office were excellent, friendly, approachable, contactable at anytime and ultimately did a wonderful job that we are very happy with. We would happily recommend them.

Bathroom Extension (with steels over existing flat)

An excellent building job done to schedule and high quality.  Peter Snelson and his team ensured that this bathroom extension was completed within 4 weeks.  Especially fast seeing as it was over the Easter break.  Quality of workmanship was high considering dealing in a small space.  Work ethic of all skilled tradesmen was also very impressive.

Rear Extension

They couldn’t work any harder if they tried.  Great communication, accurate quote, fine work and all checked by the Local Authorities to be tip top.  Very happy with our bespoke build.

Loft Conversion

We were delighted with Peter and his team.  We were impressed with the hard work shown by all of the builders on site.  We were particularly impressed by the speed (2 months) and quality of the work at a competitive price.

There was surprisingly limited disruption to family life.  Most access was from outside with toilet facilities also located outside.

As with all big builds, issues will occur.  These issues were dealt with swiftly in a professional manner.

We would highly recommend Peter and his team.

Side Extension

I had my extension done very quickly and we were really pleased with the job, especially because we were living inside for a month with a little child.  After a few unrealistic quotations (some for £75K!) we kind of lost hope until we had a realistic fair price from them.  The bots were all the time bang on time at 8am and they really worked hard.  Very happy to offer them a coffee in the morning as they arrived.  As we understood there is a jungle out there and you have to beware of cowboys or simply for company they make up price simply by looking at you and taking ages to complete as they work on multiple project at the same time.  I do recommend this company and the way they work!!!  Reliable, friendly and professional.

Kitchen-Diner Extension

Peter was hired to build an extension to my home in April last year.  The work was completed on time, within budget and, thankfully, with very little stress.  Going into any building work you hope you’ve made the right choice, and with Peter and Taras it became clear I had.  They worked hard and I can safely say I had no problems with them, they were easily contactable and reliable.  I would (and have) recommended House Extension Wandsworth to my neighbours and friends.

New back extension

Undertaking and commissioning a large building project is a daunting and worrying prospect.  Peter Snelson and his company House Extension Wandsworth, provided excellent advice from the outset and his easy methods of costing the job allowed us to price the work with variance for any unforeseen problems.

Emma Tyler, the operations manager, kept us abreast of the costs and our spend with weekly spreadsheet and pie charts.  The building team were impeccable, arriving promptly at 7.30am each morning ready to start.

I was immensely pleased with their work and this was echoed by the building.
