We specialize in providing housing and building solutions for tropical climate, islands and remote places with limited accessibility and facilities.

There are many places in ASEAN and Pacific Islands where ports, paved roads and utility (electricity and water) do not exist. The lack of local building materials and skilled labour make these places difficult to build reliable and cost effective housing. To make matter worse, there is no shortage of natural disasters to take down poorly built houses.

In view of these challenges, Grenzone housing solutions are designed and fabricated with 3 guiding principles:

  • Strong but light weight
  • Minimalist but elegant
  • Healthy, comfortable and energy efficient by design

We offer the following to meet different requirements:

Standard prefab homes

  • Most relevant for small quantity, places without construction expertise and lack of local building materials. Expensive labour and short building time frame.
  • Layout, drawings, specs of ED36 … 52, 60 etc …
  • Selection of wall types, windows and doors.
  • Rapid installation
  • Build-it-yourself

Standard semi-prefab

  • Prefab steel structures and roof support
  • Wall, windows and doors are locally sourced.
  • Suitable to places with local building materials and skilled labor.
