One option for closet shelves
We had a wonderful experience with www.easyclosets.com when we were decorating the lofts. They have an easy online interface to design your own closets and a helpful staff of closet design pros to evaluate your work and offer helpful suggestions. Everything arrived ontime and intact with extra pieces and easy to follow directions.
When we know closet dimensions we might want to go this route in the new house. We will want to have the closets INSTALLED by the building team.
We will probably have all closets built-out to one degree or another ot maximize the use of the space available.
