Constructum contracts limited
Rating: 5 out of 5
Extension Builder in Epsom
Founded in Twickenham by lifelong friends Alex and Steven, Constructum Contracts Ltd has been delivering high-quality construction and bespoke craftsmanship across Surrey and South West London since 2024. Our combined expertise spans building surveying, project management, general construction and high-end bespoke carpentry — giving clients the confidence of both technical knowledge and practical experience on every project. Steven began his career after earning a Diploma in Construction from Richmond College, working for a respected local builder specialising in loft conversions, extensions and residential renovations throughout the Richmond upon Thames area. While gaining hands-on site experience, he completed a BSc in Building Surveying at Nottingham Trent University. Following graduation, Steven worked for a multi-disciplinary building consultancy in London as a Building Surveyor, Contract Administrator and Project Manager. His portfolio ranged from residential apartment blocks to commercial properties, with particular expertise in the preservation and restoration of historic buildings in Central London. Most recently, he worked in Australia as a private Building Control Surveyor on new-build developments, before returning to the UK to bring his technical knowledge and project leadership back to clients in SW London and Surrey. Alex also began his studies at Richmond College, developing a strong trade foundation in carpentry. Coming from a family of plumbers and electricians, he was immersed in the construction industry from an early age. Over the years, he has refined his skills across multiple trades, including plumbing, electrical works, bespoke cabinetry and kitchen installations. With a particular focus on high-end bespoke carpentry, Alex has worked alongside some of Surrey’s leading cabinetry, wardrobe and kitchen installation companies. He now brings that craftsmanship and attention to detail to every Constructum project. At Constructum Contracts Ltd, we combine professional oversight with skilled workmanship. Whether you require building surveying services, structural alterations, extensions, renovations or bespoke carpentry, we pride ourselves on reliability, transparency and delivering exceptional results with the highest standards of workmanship. We look forward to seeing how we can assist with your project.

Extensions- 25 Apr 2025
we recently had the pleasure of working with Leon building contractors limited, and i cant recommend them highly enough! They carried out a single story rear extension, an internal garage conversion and porch to the front of the house. On top of that they installed our new kitchen and toilet suite downstairs all finished to a high standard. From start to finish Vic and his team were amazing nothing was too much trouble and were always happy to do anything without a fuss. Their attention to detail was first class. It wasn't only us who was impressed but our neighbors commented how friendly, respectful and hard working they all were and have already asked for his contact details. Vic trade contacts also helped us with windows/bi-folds and quartz worktops all high quality at much cheaper prices i could find myself! Thanks again to Vic and the team for doing such a brilliant job, we have no hesitation to use again in the future!

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.

Bathroom Fitting- 14 Mar 2025
My previous bathroom fitters did a very bad job with the bathroom and cloakroom toilet and left it unfinished. I am so glad I went with JM Building service as Joe and Martin completely transformed both rooms. They rectified the previous fitters errors and completed the rooms. Joe didn’t just rush through the job to get it done quickly—he took his time, ensuring every detail was finished to a high standard. He worked meticulously, making adjustments until everything looked exactly as it should, rather than settling for ‘good enough.’ His dedication to quality and precision was evident throughout, and the end result speaks for itself. As well as being very good at what they do, they are friendly, reliable, trustworthy and hardworking. I have already booked them in for another job and requested a quote for another. I highly recommend JM Building services for their professionalism and craftsmanship.

What to ask a Epsom extension builder before hiring?

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

An extension builder in Epsom 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 Epsom 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 Epsom?

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 Epsom 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 Epsom 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
