Design for a romantic summer house / sundial
Year: 2014
Designer: Willy Leenders
Details
The hexagonal construction is at least 2 m high, the hexagon has a circumscribed circle of 1 m diameter and consequently the sides are measuring 50 cm. In the middle of the roof there is a circular opening with a diameter of 30 cm.
The sun shining through the round hole in the roof projects an elliptical light spot on an interior wall. If the direction of the sun is diagonally in the hexagone, there will be two (partial) elliptical light spots, left and right of the vertical corner line. In the special case that the diagonal line has been oriented north-south, this will happen exactly on the true noon.
The two (partial) elliptical light spots together form a heart shape. Depending on the season - the sun is higher or lower - the heart shape is more or less stretched in the vertical direction and is situated lower or higher on the inner wall.
The situation for four moments in the year (the solstices and the equinoxes) is shown in a separate drawing.
The summer house so executed, is a romantic sundial for one moment each day: the true noon.
