I’m over 6′ tall. How will I fit? Do I have to have a loft?
You have 13′ vertical height to work with and you can forego the loft, and consider a Murphy bed, convertible furniture, or additional square footage.
The loft is a good sleeping area for anyone who would normally sleep on your sofa — overnight guest, children, etc. Lofts as the only sleeping area may not be realistic for someone over 50 if crawling is required. Likewise, items stored in the loft may also require crawling to retrieve them so consider the design and depth of your loft.
