Bashtan Ltd has been trading continuously since 2008, providing an all-trades building service throughout SW London and Surrey, covering Fulham, Wandsworth, Putney, Kensington, Chelsea, Kingston upon Thames and surrounding areas in Surrey.

We’ve undertaken numerous back to brick renovations, extensions and conversions using our own Bashtan labour - we don't sub-contract out - all run from our Fulham Road showroom and office. 

Each job has a dedicated project manager and site foreman and is overseen by our Managing Director, with full admin support offered by the office team. 

We design and build side return kitchen extensions, wrap around kitchen extensions, loft conversions, pod extensions and undertake all elements of internal renovations and refurbishments, too.  

If you’re considering renovation work, the first step is to send over your plans (we can quote for architectural services) for a top-line estimate. Should this fall within expectations, we'll visit you on site, walk through your ideas and prepare a fixed line-by-line quote. Once accepted, we prepare a programme of works which details all key elements of the build, along with a payment schedule and, of course, an FMB contract.  

Everything we do is transparent and we pride ourselves on our collaborative approach to building – we understand that our clients are trusting us with their most valuable asset. 

WE have the following accreditations:

- Advanced CHAS Certification

- Delta Membranes Installer

- Gas Safe Register

- NIC EIC Domestic Installer

- Considerate Constructors Scheme

We would be delighted to introduce you to some of our former clients to see our work, whether it’s an additional floor on a detached house or a glazed side return extension.

We hired Bashtan in 2013 for a full refurbishment (including side return and semi basement) of a Victorian terrace in Parsons Green. Given the nature of the project, the work went very smoothly and was done to a very high standard of finish. Throughout the job Bashtan made several suggested design changes which really helped the project to run smoothly and ensured that we got a great result. I have recommended Bashtan to others and would use them again. - J

Refurbishment of garage and workshop to gym and entertainment space. Reliable builders who worked hard to get the project completed in three months. In addition to providing a high quality finish Andy's input into the design and layout greatly enhanced the look and functionality of the space .The project came in as per the original quote apart from a few minor additions which we had approved. I highly recommend them. - M

After previously having terrible experiences working with builders in London I am so pleased to have found Bashtan Construction. They have just completed the install of a new roof and renovating our master en-suite from the studs out. The plan that I had developed for the en-suite was very custom in nature but Bashtan fitted every component perfectly. Most of the renovation was completed whilst I was abroad but I received daily communication as well progress photos keeping me in the know throughout the entire process. In addition to the exceptional quality of the workmanship and the communication being superior, I was so pleased to see that my final bill was not a pence more than my original quote. Admittedly I’m very hard to please, however, Bashtan has exceeded all expectations. They are absolutely my go-to builder and they should be yours as well. Caroline, Andy, and Yurij are wonderful to work with. Thank so much for giving us a dreamy en-suite! - L

The best builders I have ever used. I live through the building project with my family while the builder removed the roof and entire first floor and built around me. The quality of their week is excellent, their finish is amazing, communication with the client was outstanding. The build finished on time and to schedule. The builder on site were hard working, respectful and polite at all times. Their after project service is absolutely brilliant. I cannot recommend this company highly enough. - J

A full refurbishment with basement. Started and completed on time and price. Small modifications to the original plan was met with a simple ‘OK’. I could not have asked for anymore. - V
