Think of what you could do with another full floor on your house. Many houses on Nantucket were built with a crawl space basement space, which leaves little room for any use. It is usually used as a mechanical space, and rarely has any useable storage capability. Homeowners who are not permitted to further expand their existing ground cover have been forced to build down. At Main Street Construction we can offer you another full floor in your property, and our crew is involved in its construction from start to finish.
Once excavation has begun under your building, it is necessary to support the structure with cribbing and steel I-beams on all load points. When the excavation is complete, we are then ready for new footings and a full concrete wall pour at your new basement height.

The Finished Product. A full finished basement can give you so many options.

◦ Two mechanical rooms
◦ Commercial Kitchen
◦ Media Room /Theater
◦ Pool / Games Room
◦ Wetbar
◦ Custom Wine Cellar
◦ Full Laundry Room
◦ Storage Room
