December 2018 - Guilford, CT

​Just in time for the holidays, we transformed this basement into the perfect place to entertain guests. What was once a storage area has now become an additional part of this family's living space. 

Finishing your basement is a great investment because it has the potential to significantly increase the value of your home. A finished basement could be designed to included additional bedrooms, bathrooms, storage areas, and more space for recreational purposes.
