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.
Extensions are more expensive: RICS gives a guide cost of between Â£1,260 and Â£1,680 per square metre for an extension with plastered finish. So a 20-square metre single-storey extension will range from Â£25,200 to Â£33,600 â before you've put down flooring or installed a kitchen.
