Latest review:
I hired Forever Construction Ltd for the renovation of my house which included rebuilding the bathrooms and kitchen along with small wear and tear and changing the electrical wiring. The quality of work was excellent and everyone in the team paid great attention to detail making sure everything was completed to a high standard and on time. The work ethics of the entire team is commendable and I was given the best advice whenever required. My adhoc requests were also accommodated whilst making sure the timelines for the work are not missed. I found the pricing to be fair and competitive. There were no surprise charges which made the entire renovation experience very smooth. I would highly recommend Forever Construction Ltd. to anyone looking for a reliable and skilled team for any renovation/construction projects.

Roofing (Pitched)- 29 Jan 2022
Well. What can I say DS Builders came out to quote Thursday. Gave me a very reasonable qoute was that reasonable I accepted there and then. Dave and keelan came out and re pointed the chimney the next working day and was done by 2 pm yesterday.. They have also found some other roof repairs that I didn't know about they took photos to prove to me what's wrong. I've asked them to quote for the repairs.. Thanks DS Builders I've found a reliable building firm and a reasonable priced one too Would highly recommend

Loft Conversion- 20 Jan 2026
I have chosen Byron and his company to complete my loft conversion. Job was completed within given time frame. Byron and the team were polite and hard working. During the building time, any issues found by myself were addressed and rectified as much as possible. At the closing weeks of my project, I have asked Byron to complete additional carpentry tasks. He found the time to accommodate my requests. Job had some messy stages but Byron was always trying to leave site clean as much as it was reasonably possible. Thank you for your work and I would be happy to hire you again in the future.

Extensions- 6 Aug 2020
I’ve lost count of how many times we’ve said how lucky we were that we chose Bryan and his team to build our kitchen extension. The team went above and beyond to ensure as little disruption as possible, as we remained living at home whilst the work took place. During this difficult time, Bryan did everything possible to source the materials required to finish our build before our baby arrived and some how he managed it! His team were really friendly and the family miss having them around. They always tidied up after themselves before leaving too. What we thought was going to be a stressful time was in-fact the opposite. Bryan managed the whole process, kept us updated throughout and made sure the build remained on budget. The level of finish is of the highest standard, better than we could have imagined and I can’t recommend Concept enough. We will undoubtedly be using them again for work in the future. Thanks again to Bryan and his Team.

What to ask a Denmark Hill extension builder before hiring?

Before hiring an extension builder in Denmark Hill or extension building company in Denmark Hill, 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 Denmark Hill?

An extension builder in Denmark Hill 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 Denmark Hill 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 Denmark Hill?

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 Denmark Hill 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 Denmark Hill 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.
