A conventional addition is a multi-room structure that is built attached to the side of the house and is always accessible to the main portion of the home. We will make sure that the addition is seamless with the rest of the house, creating a beautiful curb appeal. This type of addition is great for living rooms, dinning rooms, bathrooms, and bedrooms.

A room addition is a single room structure that is attached to the side of a home. This type of addition is a great way to expand the size of a room, including bedrooms and bathrooms.

A sunroom is created to be a part of the home but is closed off to the interior. Sunrooms are great for the back of a home and are designed with mostly aluminum and specified glass.

We offer full garage conversions. If you are not using your 2-3 car attached garage, we can convert that space into an additional room.
