The smallest building on the estate

Ihanoya sits at the south of the strolling garden, on the path that links the tea houses of Sekisui-an and Zeku-ken with Sadokan-tei. Built in the Showa 20s, the late 1940s, it covers only about eight square metres, the smallest of the estate's registered structures.

It is made rather like the waiting shelter that accompanies a tea house, a place to pause on the way between rooms. Its hipped roof mixes materials, pantiles at the centre and copper plate around the edges.

Why it was registered

Listed on 25 May 2000, Ihanoya was valued as a model of its kind. Its role is as much scenic as functional: set on the garden path, it works as a point in the composition, a small built accent among the planting and water.

Its registration alongside far larger buildings underlines how completely the estate was conceived, down to the smallest garden structure.

Meeting it on the walk

Because it stands on the route between tea houses, Ihanoya is met in passing rather than sought out. Its small scale and mixed roof reward a glance, and its placement shows how the garden was planned as a sequence of moments.

Take it as part of the walk: a resting point that the designers meant you to notice without stopping for long.
