Welcome to The Stone House: an almost 1 1/2 acre compound directly on LI Sound with an elegant main house clad in granite & a separately deeded charming seasonal beach front cottage right at waters' edge on its own private beach. The main house - at close to 5000 sf - has an ideal floor plan. The 1st floor includes a large LR w/a granite wood burning FP & sliding doors to an expansive bluestone terrace, a formal DR, a wood paneled library/den w/another granite wood burning FP adjacent to a large eat-in kitchen w/home office & pantry. There is also a generous sized primary BR suite w/a terrace overlooking the water, a spa bathroom & extensive closets (one is cedar lined) & a guest room w/ensuite bath. The 2nd floor has a 2nd large living area w/yet another granite wood burning FP & a balcony overlooking the Sound, a BR and bath. This floor could be used as a perfect in-law suite, a private office or a getaway area in a busy household. Also included in this listing is 117 Beach Avenue, a seasonal cottage that started life as a mess hall at a R.I. army base during WW2. It was brought to Madison on a barge & placed in its current location w/the workers being paid with 3 bushels of lobster. It's now a picture book 1 BR, 1 bath bungalow with a combo LR/kitchen + a covered porch & outdoor shower. Beyond wonderful! Located at the end of a private country lane, 85/117 Beach Ave offers enviable privacy & unparalleled seaside living and is 2 miles from bustling downtown Madison.
