The site for the first iT house is in Orange County, Southern California. The iT house will be built as a guest house next to the client's main house and pool. Taalman Koch Architecture is also designing an extensive renovation for their main house, during construction of which, the clients will live in the iT house full time. Due to the zoning setbacks and existing site conditions, the iT house will be carved into the hillside necessitating the need for solid retaining walls on 2 1/2 sides of the building. Hillside grading and retaining wall work is expected to add 8-10 weeks of additional time to the project schedule.
