I commissioned Contemporary Interiors to convert my loft into a bedroom and shower room and to re-roof my house. The works were completed to a very good quality and the builder took great pains to ensure that the fit and finish was what I wanted. The various teams that worked on the project were helpful, hardworking and always willing to go the extra mile. This is a local company (North London) and I recommend it.

James replied relatively swiftly. After assessing the job, James was able to start at a mutually convenient date. We were concerned that we'd have a potential issue in matching our mortar colour-shade but James put our minds at rest and surpassed our expectations. We've since called him back to do another job for us, which he did exceptionally well too. We'd have no hesitation whatsoever in recommending him. He's punctual, reliable, trustworthy and does a terrific job. Thank you James!
