Yes. Your kitchen could be in an alley in San Francisco if you combined two homes into one. A photo below shows a former alley between two previously separate cottages that was closed in and converted into a kitchen when the buildings were combined into one residence. We enjoyed reading an article in Interior Design Homes how architect Messana O'Rorke combined two residences in space limited Pacific Heights in San Francisco. What a great way to combine living units without the cost of major reconstruction! I enjoyed seeing the unique floor lamp in the interior of the building created by Isamu Noguchi, as well as some of the interesting stone objects collected by the owners. This seems like a project that could be done without major building reconstruction and easily completed on time and on budget in our increasingly crowded world.
