Extra space for the kids, overflow for guests, an entertainment room with wet bar, or an in-law suite — today there are a lot of good reasons to renovate your basement beyond just a mancave for dad. In addition to providing additional living space, we can offer great value in the form of legal income suites. Studies have shown future buyers consider homes with secondary suites to be worth up to 10% more on average. Any way you look at it, abasement renovation could be an ideal investment.
