Question:  Can you add an addition on a split level?

Answer:   Yes, you can add an addition on a split level or bi level home.  If your yard is large enough and the city allows for the addition then adding an addition on split level is no more complex then adding a ground level or a 2nd storey addition to a single level house.  The least expensive and easiest home to build an addition onto is a single level home on a slab foundation.  Single level homes with a crawlspace cost more to originally build and also add on to because of the need of a foundation and subfloor.  Adding a second story or an additional story to a single, bilevel, split level or tri level home is approximately the same depending on the details of construction, size, etc.  So short answer is YES you can add an addition on a split level home.
