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 build cost for a simple extension can be Â£1000 â Â£1500 per mÂ². For glass extensions or high spec design Â£2000 â Â£2500 per mÂ² is more likely. For basements costs can be Â£3000 + per mÂ².
