Designer Mitchell Coll loves New Zealand and its alpine environment. When approaching the design of his home, it was a no brainer to take inspiration from the alpine huts in the Mackenzie Country he frequents to create his own slice of paradise in the centre of Christchurch city.

Just like a hut, the home is kept simple with everything having a purpose. His grapic designer partner Amy shares this approach to design, making the home a true reflection of both owners.
