About us:
Gerwyn Jones and Andrea Moffat established Plus 1 Developments Ltd in 2002, in order to provide a complete building service to the domestic market. Since then the company has established an enviable reputation for the quality of its work, which is evidenced by the amount of repeat business and recommendations the company receives.
 
Our trusted teams of craftsmen do not compromise on standards. Our projects are consistently monitored for progress and quality assurance. Once a project commences, our team remains on site until the works are fully complete. All our work adheres to Building Regulation standards. Our membership of the Federation of Master Builders Masterbond scheme is your quality guarantee.
 
We work closely with architects, engineers and party wall surveyors. Should you have your own architect or designer, we will be more than happy to liaise with them. If you do not have one, we are also able to provide a design service using our architect or design associates.
 
We will also liaise with building control to ensure that all permissions and approval are in place to enable your completed project to obtain legal sign off.

I have known Gerwyn for about 15 years. His company have previously renovated a flat for me, including a loft extension. I use him because he is extremely friendly, professional, and sticks to his quote. His workmen are very nice and they are prompt in resolving any with snagging issues which may arise - S

Plus 1 Developments Ltd have done several projects for us over the years. I find that they interpret the architect's plans very well. When they found a problem, they communicated with the architect to resolve the issue and find solutions, and only contacted us to present us with the possible options. They were on time and courteous to our family and to the neighbours, and tidied up well at the end of each day. - J
