Every week a Guardian Money reader submits a question, and it's up to you to help him or her out – a selection of the best answers will appear in next Saturday's paper.
This week's question:
Our Victorian house has a cellar/semi-basement that we are considering converting into a bedroom with ensuite shower. If you have converted your cellar, did you think it was worth it? Do they always seem dank and dark? Could it even pay for itself as a B&B room?
What are your thoughts?
