Modular Living

Sustainable Spaces & Beautiful Aesthetics

Mitrex Solar Powerhouse offers flexible modular living spaces that can be transformed into your personal office, gym, bedroom, or more! These solar-powered units produce as much energy as they consume—meaning they are carbon-neutral, sustainable options for your needs.

These units are entirely net-zero, green structures by utilizing integrated solar technology. These modular box offices are offered in three standard sizes: 16’x16’, 16’x20’, and 16’x30’. Available in various design and colour options, Mitrex guarantees beautiful aesthetics, energy generation, and a flexible living space.

The Powerhouses have two energy options—you can connect them to the grid to supplement the power demands/supply excess power back to your home, or you can opt for an off-grid self-sustaining solution. Mitrex offers supply and installation in the Greater Toronto Area and supply-only for areas outside this region. The permit process is included in the price. The units also include an R-value of 36,  a heating system and an air exchanger, and will be delivered 14-16 weeks after the order is placed.
