From the front this Sudbury home was beautiful but, if you ask the homeowners they would tell you, the back of the house left a lot to be desired. The sunken Family Room was dark and had ugly, outdated stone veneer fireplace flanked by high-set, undersized windows. The three-season Sunroom, which was accessible via sliding doors, was bright enough but with no insulation and inefficient windows, it was always too hot in the Summer and too cold in the Winter which made it only usable a few months of the year.
