How to Convert a Crawl Space in a Split Level

Small, space-wasting crawl spaces can be found in two kinds of split level housing units: the side split level unit (where the split level can be seen from the front elevation of the home); or the 3- to 4-level unit like a townhouse. Basement crawl spaces are found in other types of housing and are not difficult to convert to useful spaces, particularly if stand-up room is added. It is only in the side split and the multi-level townhouse where the crawl space is small enough to pose a challenge and resolve here.

Instructions

      Measure the crawl space for length, width, depth and height. Note pipes and ducts that are present, measure their circumferences/dimensions, identify their type and note whether they're insulated or not. Even if professionally converted, owners should be aware of the project's parameters.

      Get cost estimates and timetables, with the following itemized: air sealing of all electrical, plumbing, and duct penetrations/ vents; efficient grading and drainage to the crawl space area to keep dirt and rain water away; a multi-layered plastic vapor barrier that ends at or up the wall; vapor barrier should be further sealed with mastic tape, caulk, strips and caps to ensure a tight fit. Use fiberglass as another popular insulation alternative that is energy-efficient, made from sand and recycled glass, fireproof and inorganic. Complete the list with an installed dehumidifier and 5- to 50-year warranties on all work done.

      Create a cozy hideaway in an insulated side split level crawl space.

      Convert the insulated crawl space of a side split level into a pantry, reading nook, tiny look-out loft, storage for crafts supplies or small mementos, a mini-art gallery, by adding shelving, interlocking rubber mats, some ceiling padding (from automation suppliers or hearth suppliers)--even pillows for a cozy reading nook for children. Convert the insulated crawl space of a multi-level townhouse into a wine cellar, a cold food storage or even a secret storage/safe. Provide lights.
