Brazilian construction company SysHaus has recently installed a new prefab home that generates its own energy as it floats on an idyllic São Paulo lake. Dubbed the waterlilliHaus, the plug-and-play home is the floating version of the lilliHaus, the largest option in SysHaus’ lineup of prefab homes. The waterlilliHaus measures 3.2 meters wide by 12 meters in length and is mounted atop a floating catamaran that can be moored or sailed at speeds of up to 4 knots.

Modern, eco-friendly and adaptable, the prefab home series produced by São Paulo-based SysHaus comes in a range of sizes from the compact 9.6-square-meter nanoHaus to the 38.4-square-meter lilliHaus. All homes are prefabricated in a controlled factory environment with automated, computer-controlled machines to ensure quality, traceability and waste minimization. The units can be assembled in less than two days and can even be delivered with all of the furnishings and equipment pre-installed.

In keeping with the startup’s commitment to sustainability, all Syshaus units can be designed for off-grid use, such as the recently installed waterlilliHaus that was delivered by truck and then craned atop a catamaran at the lake. Topped with rooftop solar panels, the floating home generates all of the energy it needs. Blackwater and graywater is collected and filtered through a three-phase biodigester system; the water is cleaned before it is returned to the environment. Rainwater is also collected and treated for drinking water.

To reduce energy demands, the waterlilliHaus is punctuated with operable openings to take advantage of natural ventilation and the stack effect. Energy-efficient lighting, appliances and other electrical systems can be hooked up to a centralized smart home system for remote monitoring. The smart home system can be programmed to adapt to the user’s daily routines for energy-saving automation purposes.
