Overview: The document outlines the design and specifications of a sustainable miniHome by Altius Architecture Inc., suitable for all seasons and climates. It emphasizes quality construction, renewable materials, and optional off-grid systems.
Main Plan and Layout: The miniHome features a main plan and loft plan with a total area of 966 square feet, including a 726 square feet interior, 96 square feet loft, and 144 square feet porch. Key areas include cooking, dining, bathing, entertaining, dreaming, a screen porch, and a sleeping loft.
Exterior Specifications: The structure is built with engineered wood frame constructions on a structural steel chassis. External cladding combines pre-finished pine and Douglas Fir. The insulation system uses BASF Walltite spray applied to medium density polyurethane foam, with total assembly ratings of R33.5 for the floor, R25 for the walls, and R32 for the roof. Windows are Marvin Integrity with fiberglass clad exterior and clear pine interior. Optional features include a green roof system and solid Douglas Fir lift and slide doors.
Interior Specifications: Interior walls and ceilings are finished with Baltic Birch Ply, with birch cabinets and cork flooring. Appliances are EnergyStar rated, and lighting includes LED and CFL options. The bathroom features an acrylic tub/shower with low flow fixtures. Mechanical systems include an electric boiler for heat and domestic hot water, and an energy recovery ventilator. Optional mechanical features include a pellet stove and propane boiler.
Set Up Requirements: The miniHome can be set up without a permanent foundation using simple leveling and blocking. If a permanent foundation is needed, options include a sonotube concrete foundation, concrete pad (insulated slab on grade), or typical frost wall foundation. Setup requirements include water supply (municipal, park service, self-service), power (electrical plug-in or PV panels with battery bank), and wastewater management (septic, municipal, holding tank, gravel pit).
Zoning and Certification: The miniHome can be classified as a building or manufactured home under the Ontario Building Code. Zoning depends on location, size, use, and permanency. It is CSA certified and emphasizes no vinyl, no drywall, and quality construction.
