What Makes Us Different?

Every project and client is different. We work hard to make sure all projects are as stress-free as possible. Whether you want to retain control of your build or let us take the wheel; we work with you every step of the way. High standards are something we will never compromise on.


We provide end-to-end support on all our services and home improvements are no exception. Whether you’re dreaming of a loft conversion or renovation, installing a conservatory, adapting a bathroom, replacing a roof or need assistance with architectural planning, we can support you from start to finish.


Building works shouldn’t be a headache. We can help prepare and submit council plans and liaise with building control authorities according to requirements. Every project is assigned a dedicated project manager who’ll oversee your build and keep you up to date with progress.

Mrs Stephenson


The council arranged for Cornel's Builders to build an extension on my home. I had to live in the house whilst the works were being carried out. The lads were really understanding and helped me move my stuff, they never stopped, they even got me things from the shop when they were going, really good service.

Mrs Bell


I was looking for a new kitchen and went to one of the local building stores, they gave me a price to supply and fit a kitchen but I was faced with weeks of waiting and excuses. I contacted Cornel who got me exactly what I wanted at a better price and the work was completed within a month, really pleased and will certainly use them again.

Mr Jones


Cornel installed us a new central heating boiler, there was a problem with the existing room thermostat, they got an electrician around immediately and the plumber and electrician were there until 7.00pm to ensure it was working and we weren't without heating or hot water. We've already recommended them to family and friends.
