Overview: Chris meets architect Nic Ballara, who's planning to build a house on a steep 45-degree slope overlooking Wellington. Nic Ballara clearly has a head for heights as he starts to build a family home for him and his wife Callie and their 12-year-old daughter. Nic's site in the earthquake prone city of Wellington is so steep that it looks virtually impossible to build on, however Nic is convinced he has a solution and is determined to build his first home there. A logistical nightmare lies ahead as this Grand Design looks to be an uphill battle throughout.
