Extensions- 1 Jul 2021
Great job done by Naim and his team. He expressed interest in the job as soon as I posted. If it hadn't been for some wet weather the job would have been completed much sooner in the timescale he quoted. There was one small issue some time after the job was completed. I only called Naim once and he arranged a day to come fix it. We're very pleased with the finish, we would give future work to him and also recommend him to friends & family.

Carpentry- 12 Mar 2025
Chris was great- he installed a internal bi-fold unit which needed some considerable adjustment due to the measurements of the space it needed to go in- he took his time to understand the problem and work out a solution- the doors now works great and often get complimented by those who visit. Chris then helped fit a number of doors with handles in the property upon request- doing a great job in the process. Chris is a very tidy worker and is very good at communicating and being punctual. He was always very polite and was very careful to make sure he took care of the space he was working in at the property. He is also extremely reasonably price- would recommend him to anyone else- and will for sure contact him if I have any other jobs doing. Chris is a star!

Bricklaying- 25 May 2022
Top notch builders! We used Future Home Construction to build our large wrapround extension. They are a reliable family-owned company who showed up on time, worked hard, sometimes working 6 days a week including Bank Holidays. The team worked with great care and professionalism and were very informative, walking me through the process and offering me solutions to problems. We have been very impressed with the high standard of work carried out on our house and are delighted with the result. We would recommend Future Home Construction to anyone considering having work done to their house.

What to ask a Ongar extension builder before hiring?

Before hiring an extension builder in Ongar or extension building company in Ongar, 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 Ongar?

An extension builder in Ongar 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 Ongar 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 Ongar?

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 Ongar 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 Ongar 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.
