Garden Suites Toronto
Jash Design & Build is a luxury design-build and construction management company that specializes in Toronto garden suite additions.

Our construction costs start at $350 per square foot, with final pricing varying based on project size and scope.
Garden Suite Construction in Toronto
A detached garden suite is a secondary dwelling unit, constructed behind or beside your primary residence. These suites are built separately from the main house, including individual utility hookups.
Unlike a regular guest suite, a garden suite has its own kitchen, bathrooms, bedrooms, and common areas. Depending on the size of your lot, your unit may also be built with a separate driveway and/or outdoor area.
Garden suites can serve as a source of rental income, support multi-generational living, offer private accommodation for visitors, maximize your yard space, and increase your long-term property value.
Jash Design & Build designs and builds detached garden suites throughout Toronto and the GTA. We support our clients from early property review to design, permits, servicing, construction, landscaping coordination, and final handover.
We can build your garden suite from set floor plans or create a completely original custom build. The construction route will be determined based on your goals, site conditions, and budget.

Our Garden Suite Design Build Services
Jash Design & Build is your all-in-one garden suite builder in Toronto. We keep site reviews, drawings, inspections, permits, utilities, and finishing under one roof.
A single team overseeing a construction project from initial design through to its final stages prevents bottlenecks and mistakes from miscommunications. Here’s what you can expect from us:

Site Review & Project Assessment
We review lot dimensions, rear yard spacing, the property’s existing structures, tree coverage, and access points before starting design work. We’ll determine project feasibility and recommend next steps to achieving your project goals.

Design & Layout Planning
We design layouts around your property’s footprint, your lot’s height limits, and the separation requirements between the garden suite and main house. The design should suit your property and meet building regulations to avoid permit revisions.

Permit & Consultant Coordination
As your one-stop Toronto garden suite contractor, we provide all necessary documentation for your project, including permit applications, drawings, and consultant sign-offs. We also manage any variance work that’s required for permit approvals.

Foundation, Structure, & Building Envelope
We check soil conditions and drainage first to determine the right foundation (full concrete, slab-on-grade, or helical or screw piles). From there, we frame, insulate, and finish the exterior for a suite built for Toronto winters.

Utility Connections & Mechanical Systems
We coordinate water, sewer, electrical, HVAC, and drainage connections, as well as separate electrical metering as required. We do this in the project’s early stages to prevent delays and costly servicing errors mid-build.

Interior Finishes, Landscaping, & Handover
We help select finishes and fixtures for long-term durability and visual appeal. Before handover, we complete walkways, grading, and any fencing or gates around the suite. We also check the power, water, and heat functionality.

Garden Suite Feasibility and Zoning Review
We handle feasibility and zoning reviews before starting design or construction. Every lot presents its own challenges and requirements when building a garden suite. Your rear yard size, lot coverage, setbacks, separation from your main house, height restrictions, property access, existing trees, zoning bylaws, and servicing all factor in.
Toronto also has building rules that cap how big your suite’s ground floor can be. The limit is 645 sq ft (60 m²) or 40% of your rear yard area, whichever is smaller. If you already have a garage or shed, your garden suite plus those structures together can’t cover more than 20% of your total lot area.
We review your lot before we draw anything, rather than assume your build will match a neighbour’s. Every property brings its own mix of factors, and that’s what determines what’s buildable. This gives you a realistic number for size, cost, and timeline.
Garden Suite Sizes and Design Options
As a custom garden suite builder, we offer both custom and set floor plans. Layout options include a studio, one-bedroom, or two-bedroom suite.
We design plans based on your wishlist, along with zoning, building regulations, and site conditions. When site conditions permit, adding a second storey can increase livable space while respecting footprint limits.
Typically, layouts fall into these size ranges:
- 350 sq ft for a studio
- 500 sq ft for a one-bedroom
- 850 sq ft for a two-bedroom
- 1,300 sq ft for larger or multiple-storey builds
Your design priorities may shift depending on the purpose of the space, such as a rental versus family accommodations. For example, in a rental, you may prioritize durable finishes, in-suite laundry, and innovative storage.

How Much Does a Garden Suite Cost in Toronto?
At Jash Design & Build Toronto garden suite costs start at $350 per square foot. Pricing varies based on design complexity, number of floors, foundation requirements, customization level, interior finishes, site accessibility, lot conditions, and permit fees.
We factor utilities into your total cost planning and timeline from the very start, rather than adding them on at the end. This includes tying utilities into your existing waste and water supply and adding a separate electrical meter where required.
