Grand-Ma 550

The Grand-Ma 550 is Ma Modular's compact single bedroom model, designed for use as a guesthouse, studio, home office, or accessory dwelling unit. At 550 sq ft it offers a fully finished modular build delivered 80 to 90 percent complete from the factory. Standard finishes include bamboo flooring, fiber cement cladding, and a Rinnai tankless water heater.

Most compact ADUs leave finishes unspecified until you sign a contract. The Grand-Ma 550 names them upfront: bamboo flooring, fiber cement cladding, and a Rinnai tankless water heater, so the 550 sq ft quote is a real delivered spec, not a starting point.
