Multi-Unit Residential Design
Design and permit drawings for duplexes, triplexes, fourplexes and townhouses.
Is this you?
- You are converting a house into a duplex or triplex
- You are building a new fourplex or a row of townhouses
- You are an owner, investor or builder planning a small residential project
Multi-unit projects bring more requirements than a single house: zoning, separation between units, exits and often more consultants. Neo-Scenic holds House and Small Buildings BCIN qualifications. Each project is reviewed for the design qualifications that apply, its building classification, and whether an architect or engineer needs to be involved, before we confirm the scope.

- Where engineered roof trusses, floor systems or other specialized structural components are required, Neo-Scenic can coordinate the relevant supplier or engineer documentation with the building permit drawings.
- HVAC design is scoped separately from our architectural drawings. You can hire us for it, or use another qualified HVAC designer.
- Site servicing, grading plans and surveys, where required.
- Permit application management (optional)
- Permit application management is an optional service you can add to your design and drawing work. Drawing preparation and application submission are separate steps. Submitting an application does not guarantee municipal approval.
How it works
Initial conversation
We discuss your project and identify any zoning or municipal requirements that may need further review.
Site visit, where needed
By appointment, we measure and document the existing conditions. If a visit is needed to assess the project before quoting, it is billed separately. Where applicable, any credit for the visit toward subsequent design services will be confirmed in your written quotation.
Written quote
We provide a written quote outlining the proposed scope and fees before drawing work begins.
Preliminary design
You review the proposed layout. This stage typically includes up to three rounds of revisions. Changes after you approve the concept may involve additional fees.
Permit drawings
We prepare the drawing set and supporting documents for your permit application. Reasonable drawing revisions arising from municipal review are included.
Submitting the application
We guide you through what your project needs and prepare the drawings and documents. If you would like us to submit the application and coordinate with the municipality for you, we offer that as an optional additional service.
The full processQuestions
Can you design my multi-unit project?
We design duplexes, triplexes, fourplexes and townhouses. Each project is reviewed first for the design qualifications that apply, its building classification and whether an architect or engineer needs to be involved.
Do you work with engineers?
Where the agreed project scope requires it, Neo-Scenic Designs coordinates with qualified engineering professionals and relevant technical suppliers. Engineering services are scoped and quoted separately. Other consultants may be involved, depending on the needs of the project.
How much do permit drawings cost?
It depends on the project: its size, what already exists on site, and which drawings and documents your municipality asks for. Starting prices for common projects are shown on our service pages, before HST. We confirm the scope and fees in a written quote before drawing work begins. If a site visit is needed to assess the project before quoting, it is billed separately. Where applicable, any credit for an initial site visit toward subsequent design services will be confirmed in your written quotation.
