I froze a cake straight from the oven just to see what people were talking about. I always read that it just keeps it SOOO moist. When I thawed it (in the wrapping) the outside of the cakes were gummy and disgusting. Easy to correct, just trimmed both sides.
A loft extension can cost 30,000 to 85,000 and may add at least 25,000 to 50,000 to the value of the house. Sometimes it could add a lot more providing it creates sleeping space with an en-suite bathroom.
The price for building an extension can cost, on average, around Â£1,000 per m 2 or Â£23,000 3 for a single storey and Â£76,0004 for a double storey.
