Welcome to BuildOn Construction Limited.

We are a team of experienced builders based in Carshalton, Surrey and the surrounding areas.

We pride ourselves in producing work of the highest quality, leaving all jobs finished to the highest possible standard.
All of the work we carry out complies with the latest building regulations. BuildOn Construction Limited will handle your project from start to finish, so you don’t have to worry about a single thing. All aspects, from plans and design to build and regulations are taken care of in-house, so everything is managed under one company roof. This isn’t a service all builders provide, but we do, because it helps ensure your project runs smoothly from start to finish.

We specialise in building extensions, loft conversions and full renovations, although we also take on smaller jobs including kitchens and bathrooms. Like most good builders, the majority of our work is generated through word of mouth. This is important to us, because we believe it demonstrates consistent client satisfaction, as well as reflecting the quality of our workmanship.

Want to know more? You’ll find answers to most things on our Frequently Asked Questions page, or you can contact us directly. We’ll do our best to answer any questions as promptly as possible.

Bobby and his team converted half our garage into an office. They have done an exceptional job and we are extremely pleased with the work done. They have great attention to detail and we would recommend them to family and friends. We will definitely use BuildOn again in the near future. They are extremely polite, happy and very nice people to have around and were tidy after each day. Thanks guys !!!

Mr Martin Brown

Good Quality and excellent service!

Mrs Dorothea Francis

Bobby and his team recently put wooden floor down in my sitting room, dining room, and hallway. The quality of the flooring and workmanship was top notch. They cleaned up at the end of each working day and kept disruption to a minimum. We also had extra electrical sockets fitted and they made good any plastering where needed. All in all I found Bobby and his team to be polite, cheerful, reliable and honest. His quote was very reasonable and I would not hesitate to recommend him to anyone.

I desperately need a new bathroom, but being 90, I was somewhat nervous about the disruption.
My son-in-law recommended Bobby.It was such a relief to have such friendly and considerate people working in the house.
What’s more they did a fantastic job! I couldn’t be happier.

Alan - Sutton

Bobby and the lads did a fantastic job on our rear and 1st floor side extension. Workmanship and finish were of the highest quality.

I would recommend Buildon without hesitation.

Geremy and Kate

They were amazing and really tidy. They were fantastic and a top find.

Mrs Maud Alleyne

Bobby added an extension to the side of our house and converted the garage to make a whole new living space to our home. We were absolutely delighted with the work carried out. He was easy to deal with. I would highly recommend him.
