hmm I'm wishing we had planned more storage space. I'm hoping to put a ladder into the ceiling though. For the first time ever we have a double garage and will probably store stuff there. We've always had a single carport and one car in the elements until now. As far as I'm concerned the linen cupboard is only for linen. Ours will be a triple . We got rid of a lot of un-used linen when we moved. I will probably add more once we are in the new house. We do intend to put a broom cupboard in our laundry as well to store the brooms etc. In our last house we had the vacuum cleaner stored in the linen cupboard and I hated that it was in there. Our boys have book shelves and storage stuff in their bedrooms. ( it needs upgrading) but the priority will be replacing their beds then we'll worry about the rest.
We have plenty of room to add a garden shed and even a huge outdoor monster shed if need be, For example, we've never stored our xmas tree in the house, always , well wrapped in the shed though the ornaments have been stored inside in a drawer.
