We had planned on having a double storey extension and making a kitchen and conservatory into a kitchen diner. However we can’t afford to do it all so we have come up with the idea of just having a single storey extension and doing the kitchen diner as well. My concern is that the single storey won’t add value to the house, and having a bedroom downstairs is a bit strange. Has anyone done this has it worked out ok. Any advice would be great.
