We renovate, decorate and repurpose buildings to make sure they fully meet your needs.

Having worked in renovations for many years, we understand that it’s not about the amount of work you require. It’s about taking ownership of the space, making it yours and building it up around your requirements and expectations, so you can do exactly what you want with the building. We can redevelop and remodel a space so you can start afresh, or provide a more cosmetic refurb to give your property a new look. Our flexible approach allows us to take on refurbishment projects of all sizes and do every building justice. Regards

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.

Extensions- 17 Nov 2020
Unfortunately! Mr Sundeep Kandola is not a builder, but a corn artist who claim to be a contractor, he attended to my job, removed the old porch, then dug the ground for preparation, he then asked for a deposit of £500, which I gave him. He bought some materials and on the same day the material was delivered Mr Sundeep handed me the receipt, I refused to collect the receipt, because we have already agreed a set price for the completion of the porch, but he insisted. I then checked the receipt and saw £387.00 in total. I took the receipt and kept it. The next morning I received a text from Mr Sundeep saying that "I am sorry but I am unable to continue your work because my builder has disappointed me". I was shocked and tried calling him, but he would not pick my calls I texted him he replied saying "I am sorry" I tried again calling him, but he would still not pick my calls all day. The next day he sent me a text "if you are willing to add £500 to the total amount we agreed on I will return and complete your porch" I was shocked this was when I realised that Mr Sundeep Kandola is a corn artist, who is trying to put me in a tight Conner and I refused to be pushed. I am still looking for someone, because everyone that come around see a building site, thinks I am the problem all the builders coming around now are hiking the price of building and also asking what happened to the previous builder. PLEASE DO NOT USE THIS MAN HE WOULD DISSAPOINT YOU HE IS CLEARLY NOT A BUILDER.

What to ask a Beckenham extension builder before hiring?

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

An extension builder in Beckenham 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 Beckenham 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 Beckenham?

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 Beckenham 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 Beckenham 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.
