    “Our friends got House Extension & Conversion Advisory Service to their drawings and we decided to use them as well. We had a quote from a local architect to do the drawings for £4900- House Extension & Conversion Advisory Service were less than half that amount. They gave us great service and we have received approval from the local authority we are now getting quotes for the job. I am happy to recommend House Extension & Conversion Advisory Service.”

    “We needed more space but didn’t know how to go about it or what it might cost we had a couple of builders in to give us advice but that was a bit of a waste of time. I was recommended to contact House Extension & Conversion Advisory Service and they came out and gave us a really great design and a cost of what it should cost us. We really liked his ideas and took their architectural package. We got planning permission in 2 months and we got quotes for the extension we went with one of the contractors they introduced us to, as we felt confident in them and they gave us references and were the lowest quote. The job was finished last June and we love it. It has made such a difference to our house. We would definitely recommend House Extension & Conversion Advisory Service to anyone getting this type of work”
