Hi We had plans drawn up by Architectural guy for single storey extension on back of bungalow with flat roof 8m x 4m - got go ahead from planning permission and building control. Kitchen, utility and dining. Utility will be stud wall. Will require electrics all plastered plumbing and drains. No units etc. Had builder round and he says we need structural engineer and quantity surveyor. Is this correct? I thought it would be pretty straightforward but has taken 6 months and builder says it will take another few months to get all info to even give me a quote
Can anyone advise please.
