House N was built by a son for his 90-year-old mother. Located in Sapporo, Hokkaido, where the snow lies up to 140cm deep each winter. House N was to replace the existing house.
As the mother was not well enough to move out of the old house even temporarily while the new house was under construction, our plan was to build the new house while leaving the old house for the mother to reside in.
Effort was made to leave as many trees as possible on the premise in order to preserve the view from the windows.
House N is comprised of 6 box units. Three boxes were initially constructed while the mother remained in the old house. After the three boxes were constructed, the mother moved in to the new house. The old house was then taken down and the remaining three boxes were completed.
