If you’re looking to make your property bigger, you might want to consider property extensions. This can include expanding rooms horizontally (outwards) or vertically (upwards), increasing living space, or even adding new functional sections such as a home office, playroom, or sunroom. Property extensions can greatly improve the usability and value of your home while also giving a customised response to your changing demands without requiring you to leave.

Our dedication to employing premium materials and cutting-edge construction processes guarantees that your extension is not only aesthetically beautiful but also durable and long-lasting.
JP Refurbishment London specialises in customising property extensions to meet your specific needs. Depending on your demands, we can add extra rooms, create an open floor plan, or even build a two-storey extension. Our method entails carefully matching the design aesthetics with your current property so that the new space feels like a natural extension of your home. We also prioritise utilising natural light and the optimal use of space to build an extension that enhances your living experience.

Our experts help design a practical and aesthetically pleasing extension tailored to your property’s style.
We handle the building process, from groundwork to finishing touches, ensuring high-quality workmanship.
Upon completion, we perform a final inspection to ensure everything meets your expectations and the highest standards.

In our first meeting, we’ll discuss your design choices, help you understand how to get planning permission if you need it, and guide you on the best layout and structure for your needs. This will ensure that your vision is clear from the beginning.
We will provide you with a detailed quote and timeline for your project. The quote will include everything. It covers necessary applications, permissions, structural engineers, and other legal needs. It also includes party-wall agreements and building regulations, ensuring no surprises throughout the project.
Before construction begins, we’ll have a meeting to kick off the project so you know exactly what to expect. Our project managers will oversee the entire build, ensuring everything runs smoothly and stays on schedule. We’ll keep you updated every step of the way so you’re always informed.

Your satisfaction is our priority. Once the work is done, we’ll inspect the entire project with you to review any remaining snagging items.

EXCELLENT Based on 29 reviews Posted on Google juan fernandez2026-05-09Trustindex verifies that the original source of the review is Google. Our experience as an architect and project manager with JP Refurbishment has been excellent. They are a family-run company with many years of experience behind them. The standard of detail and finish is very high, and whenever there were any supply issues with the products specified in the project, they were very proactive in offering several alternatives, all of which were acceptable. They carried out the work for a complete refurbishment of a flat in central London, in Pimlico, including the three bathrooms, kitchen and the painting and redecoration of the entire property. They also completely renovated the services (heating, electricity and hot water). They were also impeccable in keeping the site tidy and clean with regard to the residents’ association. For us, it was also an added bonus that they spoke Spanish and had extensive experience in the construction sector in Spain, as, being Spanish ourselves, this made communication much easier. We can wholeheartedly recommend Jon, Jorge and their entire team.Posted on Google Alma Messiez2025-10-30Trustindex verifies that the original source of the review is Google. We recently had JP Refurbishment carry out work on our hallway, living room and kitchen, and we couldn’t be happier with the results. Jon and his family team take real pride in what they do — their craftsmanship and attention to detail are fantastic. It’s clear that making the customer happy is their top priority. We appreciated the detailed estimate and the communication along the progress. We feel absolutely at home in our beautiful living room now thanks to them. This is a busy company, which says a lot about the quality of their work, but they still managed to deliver a great finish that exceeded our expectations. We would happily recommend JP Refurbishment to anyone looking for reliable, high quality, friendly builders.Posted on Google Saba Fatima2025-09-17Trustindex verifies that the original source of the review is Google.

JP Refurb helped me with some carpentry after I had been badly let down by another builder. They were professional and kept in touch with clear communication.

Would be happy to recommend them to others.Posted on Google Sasha2025-07-27Trustindex verifies that the original source of the review is Google.

Thank you!Posted on Google George Noah2025-07-07Trustindex verifies that the original source of the review is Google. We were nervous choosing a refurb company, but Jon and his amazing team transformed our tired old apartment into something straight out of a 5-star hotel. They sent regular updates, and made the whole process smooth even while we were away in Dubai. Truly brilliant people!Posted on Google ONWE EBUKA2025-07-01Trustindex verifies that the original source of the review is Google. We entrusted JP Refurbishment with a full house renovation, and it was the best decision we made. Jon managed plumbing, flooring, tiling, decorating, and more with such care. Every room now feels brand new. The attention to detail and teamwork was exceptional. They delivered on time and on budget—true professionals!Posted on Google Amelia Southgate2025-06-26Trustindex verifies that the original source of the review is Google. Jon and his crew were outstanding during our roof restoration. They cleaned, repaired, and treated the roof with care and detail. The waterproof coating looks and performs brilliantly. The team was on time, polite, and respected our property. True craftsmanship is rare—but these guys have it.
