Overall it seems to be exactly what was asked for. My only minor negative remark is the spiral staircase. I know there isn't really any room to do a traditional staircase but as a real estate agent I have never heard anyone say positive things about spiral staircase. It certainly isn't a deal breaker and gives access to the added space that is needed. Overall I think the aesthetic's match the current beach bungalow theme and integrate well into the existing structure. Thumbs up from me. I would make the glass door from the new living space to the patio a three panel sliding pocket door so you can open the entire door way up to the outside.
