Project Description

Jack and Annie Smith live in a four-bedroom home in Green Bay, Wisconsin. The couple recently found out that Annie is pregnant with their third child. Currently, the only spare bedroom in their house is being used as Jack’s office, so they’ve decided to hire a contractor to build a 12’ x 12’ addition on the ground floor.

Objectives

A 12ft x 12ft room should be added to the home on the ground floor.
The project must be complete by mid-February 2020.
The project should not exceed $30,000.
The home must remain safe and usable for family during the renovation.
All materials used should meet the safety and efficiency standards expressed in the Wisconsin Uniform Dwelling Code and The International Building Code.
Design elements of the original home (such as siding, window design, and roof) should be used to blend the addition into the existing structure.
