Addition House Plans

If you already have a home that you love but need some more space, check out these addition plans. We have covered the common types of additions, including garages with apartments, first floor expansions, and second story expansions with new shed dormers. Even if you are just looking for a new porch to add country charm and value to your house, we have that, too! Our additions are detached or made with smaller Cape Cod, bungalow, and Craftsman houses in mind. They also come with different uses—some create new master suites or bedrooms, while others increase living spaces and offer brand new, expanded kitchens. These additions have been made available as generic stock plans, and if they can be adapted to your existing home, they offer a less expensive alternative than having custom plans drawn up. If you need assistance choosing an addition, please email, live chat, or call us at 866-214-2242 and we'll be happy to help!
