Outdoor carpet has been used, but we find that it traps moisture and promotes rot, even when using treated wood. One solution we've found to this problem, is to apply rolled asphalt roofing to the ramp surface. For more information go to wood ramps . An alternative could be the installation of an automatic door opener, but they are very expensive. We don't recommend an accordion door because of the space it takes up in the door opening.
Pocket doors can be an option.
Look out for plumbing and electrical lines. If there's utilities located in the wall you can consider double wall installation. Under counter base cabinets can be removed to provide access to the sink or work area. A pull out or drop leaf shelf can be added for working space. Sliding shelves can be installed in lower cabinets.
