WC Supplies is bringing prefabricated cabins and accessory structures to Vancouver Island. Built off-site for quality and efficiency — ideal for guest suites, seasonal worker amenities, home offices, workshops, or additional covered space on your property. Modern design meets practical Island living.
Prefabricated cabins and accessory structures are built off-site in a controlled factory environment, then delivered and placed on your property. They range from 200 to 600+ square feet and come in a variety of configurations — from single-room studios to multi-room layouts with kitchen, bathroom, and living areas.
Unlike traditional construction that can take months, prefab structures can be delivered and set up in a fraction of the time. Built with insulated panel construction suited to coastal climates, they’re designed for year-round comfort on Vancouver Island.
Give family and visitors their own private space without a full home addition. Suitability as a sleeping unit depends on your property’s zoning and local permit requirements — check with your municipality.
On-site break rooms, office space, or seasonal shelter for farm workers. A practical addition for Cowichan Valley farms and ranches. Suitability for year-round habitation depends on certification and local zoning.
Add attractive, self-contained space to your property. Whether short-term rental regulations apply depends on your municipality’s zoning rules — check with your local government before listing.
A dedicated, quiet workspace separate from your main home. Ideal for remote workers, artists, or anyone who needs focused space.
A step up from a standard shed — insulated, secure, and designed for year-round use as a workshop, tool room, or equipment storage.
Whether you need extra room for hobbies, a garden room, or flex space on your property — prefab cabins offer a versatile, quick-to-deploy solution.

Whether you’re on a farm in the Cowichan Valley, a rural lot near Duncan, or acreage in Mill Bay — we can help you find the right structure for your property.
In most cases, yes. Permanent structures and many accessory buildings require a building permit from your local municipality. The requirements vary by area — the Cowichan Valley Regional District, Municipality of North Cowichan, and City of Duncan each have their own rules. Brad can point you in the right direction, but it’s the buyer’s responsibility to confirm permit requirements and secure approvals with their local authority.
It depends on the unit and your site. Options include concrete slab, helical piles (screw piles), or concrete pier blocks. Our team can help with site prep and foundation work using our excavation services.
Many Vancouver Island municipalities allow short-term rentals in accessory structures, but regulations vary significantly. Check with your local government for zoning requirements before purchasing a unit for this purpose.
Once your site is prepared and the unit is manufactured, delivery and placement can often be completed in a single day. Total timeline from order to placement is typically 8-16 weeks depending on the configuration.
Units can be configured with solar panels, alternative heating, and other off-grid features. However, options like composting toilets and rainwater collection are subject to local health and zoning approval. Check with your local authority before specifying off-grid systems.
Units range from compact 200 sq ft studios (ideal for offices or workshops) up to 600+ sq ft multi-room layouts with kitchen, bathroom, and living areas. Contact Brad to discuss what configuration works best for your needs.
Important Notice: Units are sold as accessory buildings. The buyer is responsible for confirming permitted use, zoning compliance, and obtaining all required building permits with their local authority (Cowichan Valley Regional District, Municipality of North Cowichan, City of Duncan, or other applicable jurisdiction). WC Supplies makes no representation that a given unit will be approved as a dwelling or for any specific use on any specific property. Certification details for each unit are available upon request — please confirm the applicable standard and certifying agency before purchase.
