Our Story

Over 15 years ago, Alexander Hruby, an engineer from Austria, began building houses in Costa Rica. The first thing he noticed was how difficult it was for prospective house owners to understand their new environment. So, he created Manu Prefab, a full service, design and build company that specializes in modern tropical prefabricated homes. The focus was on how to embrace the natural landscape, environment, and sunsets while balancing sustainability and strength of construction materials.

Hruby has traveled all over Bali, Hong Kong, Japan, Malaysia, and China examining tropical architecture and materials. He has experimented on his own houses with wood, steel, Covintec®, SIPS, and concrete blocks to find the perfect match between welcoming nature and protecting the structure and its inhabitants from the heat and humidity.

Recently, Alexander moved his attention away from wood frames to focus on galvanized steel frames in combination with Structural Insulated Panels (SIP), which are lightweight Styrofoam core bound between two sheets of Fiber Cement Panel. SIPs are lightweight, very strong, used for walls, floors, and roofing, manufactured under factory-controlled conditions, and can be designed to ft any type of building. Now, MANU Prefab can reduce costs and create better visual communication using the SIP panel format.

Manu Prefab not only builds wood houses using traditional Balinese techniques of interlocking joints,but now they also offer a new, modern, high-tech, green choice to build tropical homes with insulated SIP panels.
