Wellington ( a bit like parts of Queenstown ) is known for steep slopes and high winds , so the actual design will affect things a lot -- my sister once 'conned' me into moving her to Wellington when she got a Government job . We loaded one of my small trucks and drove several hours , when we got to her new place on the side of Mt Victoria with lovely harbour views , it seems she had forgotten to mention that the new house was the one up there -- yes , a 1920's build 130 steps up from the street . Hard enough moving a glass fronted china cabinet and solid Kauri 1880s dining table -- imagine carting every bit of timber , tile , window , kitchen appliance up there !
