While a good idea may not be a bad alliteration, I couldn’t help myself. Bad word-smithing aside, a good idea may be to locate the ladder to the loft at the rear of the house.
The example pictured here is from Tiny House UK. This tiny off-grid house puts the bed closer to the open side of the loft which would lessen any claustrophobic feelings. The cost is a bit of floor space down below on the left.
