Architecture collective Frankie Pappas has hidden the 3.3-metres-wide House of the Big Arch within the Bushveld nature reserve in the north of South Africa.
The unusual form of the skinny house is a direct result of its unique location within a nature reserve, surrounded by forest and alongside sandstone cliffs.
The house's long, thin shape was determined by the location of the trees so that not even one tree had to be felled during its construction.
