Established in 1985

We are a company that is experienced in all aspects of building, specialising in domestic extensions and general building alterations.

On site at all times

So the horror stories you hear of builders starting many projects at the same time and spending weeks away does not apply to us.


We encourage people to gain references from our previous customers. We also have a portfolio available for inspection.

No deposits

We do not take any money as a deposit and the first stage payment is only due once the work has commenced.
