Residential Services by Project Type
Custom Home Design
Design a new home around your property and household, coordinating layout, daylight, privacy, interiors and building performance from the beginning.
Renovation and Addition Design
A major renovation begins by understanding the existing structure: what is worth retaining, what limits the way it functions, and where change can provide the greatest benefit.
Projects may reorganize the interior, add a rear or side addition or new storey, improve the relationship to outdoor space, increase daylight, or upgrade the building envelope and systems. Existing structure, zoning, building code, heritage conditions, mechanical systems, and construction sequencing all influence the design.
Existing and new work are developed as one coherent home, with natural light, circulation, material transitions, structure, building performance, and daily use considered together.
Multiplex Design
Plan more than one complete home on a property, with unit mix, access, privacy, shared systems and ownership goals considered from the beginning.
Laneway House and Garden Suite Design
Test a separate rear home against access, trees, servicing and the main house, then develop a compact plan suited to its intended use.
Integrated Residential Interior Design
Interior design develops as part of the architectural project, coordinating space planning, millwork, lighting, finishes and built-in details.
Still Defining your Project?
You may be comparing renovation with new construction, testing a multiplex, considering a secondary home, or reviewing a property before purchase. The first step is to identify which questions must be answered before design begins.
Approvals, Permits, and Regulatory Coordination
Specialist services include Committee of Adjustment submissions and hearing support, permit and construction drawings, ravine-property review and condominium applications. The relevant service page explains the process, professional responsibilities and supporting advice.
Specialized Residential Projects
Some projects sit outside the studio’s principal service categories but draw on the same design, approval, technical, and construction experience. We are open to discussing them where that experience can contribute meaningfully to the project.
Cottages and Recreational Homes
Contemporary residential design for waterfront, rural, and recreational properties across Ontario, shaped by landscape, access, seasonal use, servicing, and the particular conditions of the site.
Heritage and Character Home Upgrades
Renovations that improve space, comfort, energy performance, and long-term use while working carefully with the existing proportions, materials, and architectural character of the home.
Specialized Experience Within Larger Residential Projects
Across custom homes, renovations and additions, multiplexes, laneway houses, and garden suites, we have developed substantial experience with project requirements that often form part of a broader residential scope.
Multigenerational Homes
Homes planned for several generations, with an appropriate balance of connection, privacy, accessibility, independent living, shared space, and flexibility over time.
Secondary Suites and Lower-Level Renovations
Legal secondary suites and lower-level living spaces designed with attention to natural light, ceiling height, circulation, privacy, building-code requirements, and long-term adaptability.
Top-Up Additions
New storeys designed where the existing structure, zoning, building form, and project goals make vertical expansion a viable way to add space.
Feasibility and Advisory Services
Early advice can be valuable before a property is purchased, a project scope is fixed, or substantial design work begins.
Pre-Purchase Feasibility Studies
A review of zoning, available property information, existing conditions, site constraints, likely approvals, and potential project directions before an offer is made or a purchase becomes firm.
Property Consultations
A focused discussion and review of a particular property, existing home, or early project idea. This can help identify the principal opportunities, constraints, and questions that should be investigated next.
Zoning and Construction Due Diligence
A more detailed assessment of what may be built, which approvals and consultants may be required, and which existing conditions could influence design, cost, timing, or construction.
For properties where several development directions need to be tested together, our Pre-Design Study brings zoning, site conditions, building-area options, approvals, construction considerations, and preliminary budget into one early assessment.
Some of the most important project decisions are made before a design is developed. Clarifying the realistic options at the beginning helps direct time and investment toward the most viable path.
High-Performance Homes
Building performance is considered as part of the residential design process.
Depending on the project, this may include Passive House-informed design, Net Zero objectives, all-electric systems, improved insulation, high-performance windows, airtightness detailing, balanced ventilation, low-VOC materials, and durable envelope assemblies.
The appropriate strategy depends on the site, existing building, project scope, budget, and client priorities. The objective is to identify measures that meaningfully improve comfort, health, energy use, durability, and long-term operating performance.
We coordinate these goals with the architecture, structure, mechanical design, material choices, and construction details so that building performance supports the overall quality of the home.
A Scope Matched to the Project
No two residential projects require exactly the same services. The appropriate scope depends on the property, the project type, the approval path, and the client’s desired level of involvement.
Establishing the Right Starting Point
Some projects begin with feasibility or a property review. Others are ready to proceed directly into design. We identify the questions that should be answered first and establish the studies, consultants, and approvals likely to be required.
Defining the Required Documentation
A building-permit package, construction-document set, interior-design scope, pricing package, and construction-guidance service each serve different purposes.
We define these deliverables clearly so that clients understand what is included, what information will be available to consultants and contractors, and how each stage supports the next.
Coordinating the Project Team
Structural, mechanical, grading, surveying, arborist, planning, and other consultants are coordinated according to the project’s needs.
Their work is developed within the architectural direction established for the home, allowing technical requirements and design decisions to remain connected as the project advances.
Direct Involvement Through Construction
The level of construction involvement is established as part of the wider service scope.
For some projects, the studio responds to defined questions and conducts selected site reviews. For others, we review pricing and invoices, coordinate contractor questions, prepare recommendations, and bring forward the decisions requiring client approval. Clients continue to work directly with Felix through the agreed phases.
Begin with a Conversation
The complimentary 20-minute call establishes the broad project, whether the project and studio are a good fit, and the appropriate next step. It is not a design consultation or feasibility review.
A one-hour consultation or Pre-Design Study is available when the property, options, constraints, or likely approvals require specific analysis.
