What makes a house plan specifically suited to be called a Lake House Plan? It is not a specific architectural style, although typically homes build on a lake tend to be of a Rustic, Country, or Cottage style. But that doesn’t mean a Contemporary style house wouldn’t be at home on a lake front property.
Really, what makes a Lake House Plan is the plans ability to take advantage of the views. You will want family rooms, leisure rooms, kitchens and dining areas to all take advantage of great views of the lake. The reason you are there is to enjoy the outdoors, so a Lake House plan had better have plenty of outdoor living spaces.
Features like outdoor fireplaces, screened porches, and walk-out basements are just some of the things that help to define a Lake House. Of course you’ll want other less Lake related features like plenty of storage and extra bedrooms for all the guests you’ll be entertaining. After all, a family with a Lake House always has a few extra friends.
