Westlake Avenue

Tropical modern, in two characters.

  • Westlake Avenue, Singapore
  • District 20
  • 2 Semi-Detached houses
  • Completed
  • 2024–2025

Two houses on one address, named for a tree and for a sea. Tembusu takes a garden; Caspian takes water.

Rather than build the same house twice, the land was split by how each home would actually be used. The Tembusu House takes a garden theme and suits multi-generational living. The Caspian House takes a water theme and is built for entertaining.

How the house was thought through.

  • Planting along the pool edge at The Caspian House, the living level open to the garden.

    Landscape doing the work.

    Where land went to pools, planting came back onto the facade. The exterior is deliberately porous, so the outdoor rooms stay usable in the heat.

  • The living room at The Caspian House opening fully onto the pool, with the waterfall beyond.

    A garden, and a gathering.

    Tembusu gives over a quarter of its land to greenery, with a sunken alfresco lounge and timber deck. Caspian answers with a cascading waterfall, an L-shaped pool flowing into a jacuzzi, and an attic spa off the master bedroom.

  • The Caspian House from the street, its planted ledge running the width of the elevation.

    One site, two audiences.

    Rather than build the same house twice, the plot was split by how each home would actually be used — one for family, one for guests.
