A couple bought this house with the intention of having a family there. They need more space to make this a reality as the house is too small. They want a nice area to spend time as a family in as well as being able to have other family over. Having both an outdoorsy area and a nice family room would accomplish those things. This would be accomplished with and extension. This extension includes a large spacious family room with a bedroom, bathroom and exercise room connected through a catwalk. On the roof of the cylindrical section would be a roof garden.
