The site originally was a coconut plantation , situated between the beach and the coastal railway line.
The hotel was commissioned by Ajit Wijesekera of Union Apparel a garment manufacturer in , the design of which was a collaboration between Geoffrey Bawa and Milroy Perera. The hotel was one of Geoffrey Bawa's last major projects,  which Patrick Kunkel of ArchDaily believes "represents a slightly more minimalistic approach to his architectural design informed by his earlier work.
For the building design Bawa returned to a simple rest house layout, which he first used in for the Serendib Hotel, but reinterpreted on a grand scale with expansive courtyards and limitless vistas. The main entrance is a lofty porch , with an enclosing wall which screens the hotel from the adjacent railway line. The entrance doors open out to a long axial arcade running across a large garden court, past the hotel lobby and out through the coconut grove towards the sea and the horizon.
