CAD / Drawings- 20 Aug 2019
I hired Mr Simon Javens of JavensDesign and found him to be very professional and able to turn around a difficult planning application accurately and quickly complete with fully CAD design specifications. He is willing to go the extra mile to liaise with third party agencies, be it the Council or previous structural surveyor(s) and architect(s). A very pleasant chap indeed. You will not regret hiring his services. I received excellent advice in every step of the journey - Simon is very knowledgeable and willing to help. I would recommend him 100% and will definitely use him again. Thank you Simon!

Had work carried out by RS construction recently, was an overall pleasant and stress-free experience, had a dormant chimney breast removed all the way through my property. Which had to be removed due to constant leaks and repairs by previous roofers. Ross was very helpful and knowledgeable throughout the project and his team kept my house and garden very clean considering the work that was undertaken, it has not only freed space within my property but given me peace of mind concerning continuous leaks, which have caused numerous issues over the years. Can't recommend this company anymore , from sale to completion a very professional and helpful service

Extensions- 22 Apr 2019
Richard and his team have always been very hard working, respectful and professional throughout the project. We have had an extension, utility and bathroom/toilet renovation and we are very happy with the quality of work. It has transformed our home into a beautiful living space. Richard was very helpful when giving advice on materials we were choosing. The team were very accommodating to our needs, easy to work with and always tidied up after themselves. The payment schedule made it easy to keep on top of the budget and pay for any optional extras along the way. The building work was completed within the set timescale and to a high standard. We would highly recommend Lux for any building/renovation work.

Please avoid this company for many reasons. There work is absolutely shocking and the owner is incompetent and should be ashamed of himself how he left my job. I’ve tried to contact Elijah and he’s blocked me, he’s an absolute disgrace. I will put up pictures of his work so you can see how bad his work is.

Bathroom Fitting- 8 Jan 2026
We couldn’t be happier with the bathroom and toilet refurbishment carried out by Sahir. From start to finish, the workmanship was outstanding and the attention to detail really shows in the final result. The spaces have been completely transformed and finished to a very high standard. Sahir was professional, reliable, and respectful of our home throughout the project, always keeping the area clean and tidy. Communication was clear and honest, and everything was completed on time. We’re absolutely delighted with the results and would highly recommend them to anyone looking for high-quality refurbishment work. A truly excellent job!

Kitchen Fitting- 18 May 2017
Cannot fault the work Tony undertook. Completed on time, finished to a very high standard, kept informed (we were away on holiday whilst work was being done). So pleased with the result, my daughter's room is what was the kitchen and looks beautiful. New kitchen fitted with new floor tiles and looks fantastic, boiler was moved etc. Can't recommend Tony enough and I will definitely use Marsdens again.

Architecture- 20 Nov 2016
This is the first time we are carrying out an extension work at our property. Sean worked with us from a very early stage, prepared the drawings, coordinated with the council and ensured that we received the building approval on time. He was always available to advice us (when requested) on design challenges, choosing installers and material choices which we found very helpful. We are very happy with his work and thoroughly recommend him.

Restoration & Refurbishment- 5 Apr 2025
Where do I begin? So Alex and his team has pretty much renovated two flats including external work such as roofing. The work involved was quite challenging as the building has a lot of damp / mould / leaking issues. Alex’s attitude towards resolving every matter was exemplary. He would take his time to explain his strategy to tackle each and every problem in a very metholodical way. I have never seen anything like it. I am so pleased with Alex’s work and so are my tenants who live in the flats. I would highly recommend Alex, especially for tougher jobs!

What to ask a Nunhead extension builder before hiring?

Before hiring an extension builder in Nunhead or extension building company in Nunhead, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Nunhead?

An extension builder in Nunhead should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Nunhead extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Nunhead?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Nunhead extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Nunhead extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
