A dormer loft conversion extends out from the existing roof to create extra headroom and floor space. It is one of the most popular options, improving light, space, and overall usability of your loft.

A hip-to-gable conversion changes the sloping side of the roof into a vertical wall, creating more internal space. It is ideal for semi-detached or detached homes needing extra room and better layout.

A mansard conversion involves altering the roof structure to create a near-vertical wall and flat roof. It maximises loft space, giving a large, full-height room ideal for bedrooms or offices.

An L-shaped loft conversion combines two dormer sections to create a larger, practical living space. It is perfect for properties with rear extensions, offering multiple rooms or a spacious master suite.

A Velux loft conversion uses roof windows without changing the roof shape. It is a cost-effective option that brings in natural light while keeping the existing roof structure intact.
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.

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.
