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!

High quality and impeccable workmanship are key values to me and ensuring the client is satisfied and more with the work they are receiving.

I am very well connected with all trades and can provide a top tier service for all types of project management no matter how big or small the job may be. I am also extremely capable at doing many manual labour jobs, but often favour a shorter timeline for my clients project completion and therefore prefer to draft in experienced trades to get the job completed. Above all I am very friendly, well spoken and always keen to deliver what is asked of me.
