Residential Architectural Design Services in Toronto
Our work is centred on residential design, with the scope shaped around the property, program, approvals, and level of involvement each project requires
baukultur/ca is a Toronto residential design studio providing residential architectural design and integrated interior design for homeowners, property owners, and boutique residential developers across Toronto, the GTA and beyond.
Most of our work centres on custom homes, major renovations and additions, multiplexes, laneway houses and garden suites. These are our principal areas of experience rather than fixed boundaries. We also consider projects outside these categories where the site, program, context, or particular design challenge makes our experience relevant.
Interior design is developed as an integrated part of the architectural project rather than offered as a stand-alone service. Depending on the project and agreed scope, our work can extend through feasibility, zoning, municipal approvals, consultant coordination, building permits, construction documentation, pricing, interiors, and construction.
The appropriate scope depends on the property, the project, and the decisions that need to be made. Some clients begin with a clearly defined home. Others are comparing renovation with new construction, testing whether a multiplex is viable, considering a second home on an existing property, or reviewing a property before purchase.
We establish what is realistically possible, define the project, develop the architectural response, coordinate the required expertise, and carry the work forward as it becomes more detailed.
Residential Services by Project Type
Custom Home Design
A custom home begins with a particular site and the life its owners want to build there.
We study zoning, orientation, views, neighbouring properties, trees, access, street presence, garden connections, privacy, and changing daylight. These conditions establish the framework for the plan, building form, interior spaces, materials, structure, and building performance.
Depending on the agreed scope, our custom home services can extend from site evaluation and feasibility through schematic design, design development, consultant coordination, municipal approvals, permit and construction drawings, interior design, contractor pricing, and construction guidance. The home is developed specifically for its property and inhabitants, with architectural quality, technical performance, and construction considered as parts of the same project.
Renovation and Addition Design
A major renovation begins by understanding the existing home: what is worth retaining, what limits the way it functions, and where change can provide the greatest benefit.
Projects may involve reorganizing the interior, adding a rear or side addition, creating a new storey, improving the relationship to the garden, or upgrading the building envelope and systems. Existing structure, zoning, building code, heritage conditions, mechanical systems, and construction sequencing all influence the design.
We develop existing and new construction as one coherent home, with careful attention to natural light, circulation, material transitions, structural integration, building performance, and the way the renovated spaces will support daily life.
Multiplex Design
A multiplex begins with understanding what the property can support and what the project is intended to achieve.
baukultur/ca designs duplexes, triplexes, fourplexes, fiveplexes, and sixplexes for owner-occupiers, multi-generational families, groups building together, rental-property owners, and boutique residential developers.
Unit mix, entrances, circulation, natural light, privacy, acoustic separation, structure, services, storage, outdoor space, ownership goals, and the relationship to the neighbourhood are considered together. Each unit is developed as a complete home, while the building is planned as one residential whole. Where individual ownership is intended, condominium-registration requirements are considered from the beginning.
Laneway House and Garden Suite Design
A laneway house or garden suite can provide rental income, a home for family members, space for aging in place, or greater flexibility within an existing property.
The design begins with feasibility. Zoning, emergency access, existing trees, privacy, servicing, parking, lot configuration, grading, and the relationship to the main house all influence what can be built.
Within a compact footprint, daylight, circulation, storage, room proportions, outdoor space, built-in elements, and window placement require particular care. We carry the project through design, consultant coordination, municipal approvals, building permits, construction documentation, and construction according to the agreed scope.
Integrated Residential Interior Design
Interior design is developed as part of our architectural projects rather than as a stand-alone service. It is most effective when it develops with the architecture from the beginning.
We coordinate space planning, millwork, storage, lighting, fixtures, finishes, material transitions, and key interior details with the structure, building systems, natural light, and overall organization of the home.
This approach allows practical elements to contribute to the architecture. A stair can bring light into the centre of a plan. Built-in storage can define a room. Material changes can clarify circulation and establish hierarchy. The result is an interior that feels connected from the overall plan to the details encountered every day.
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
Residential projects in Toronto may involve several approval authorities and technical consultants. Identifying the likely path early helps the design respond to the applicable requirements before significant work is committed.
We prepare architectural submissions, coordinate consultants, respond to municipal comments, and carry the project from feasibility through approval and permitting within the agreed scope.
Committee of Adjustment, Severance, and TLAB
Where a proposed project does not comply fully with the applicable zoning by-law, a minor variance application may be required. Some properties or ownership strategies may also involve severance, consent, or a Toronto Local Appeal Body process.
We identify these requirements during feasibility, develop the architectural information needed for the application, coordinate supporting consultants, and remain involved through hearings, decisions, and subsequent permit work according to the project scope.
Building Permits and Construction Documentation
Building-permit drawings communicate the information required for regulatory review and demonstrate compliance with the applicable building requirements.
Construction documentation develops the architectural design further for pricing and building. It can include more detailed assemblies, dimensions, material information, coordination, interior details, and clarification of how the work is intended to come together.
The required level of documentation depends on the project and the contractor relationship. We establish that scope clearly so clients understand the difference between an approval package and the information needed to price and construct the work.
TRCA, Ravine, and Urban Forestry Approvals
Ravine properties, regulated slopes, conservation-authority areas, and sites affected by protected trees require additional care from the earliest site review.
We coordinate architectural design with Toronto and Region Conservation Authority requirements, the City’s Ravine and Natural Feature Protection framework, Urban Forestry, arborists, grading consultants, surveyors, and other specialists where required.
Addressing these conditions early allows the project design, consultant work, and approval strategy to develop together.
Condominium Registration
Multiplexes and other small infill projects intended for individual unit ownership benefit from early planning for condominium registration.
Unit boundaries, shared elements, services, access, parking, storage, outdoor space, and building systems can all affect the registration strategy. We coordinate the architectural information with the client’s legal, surveying, engineering, and development team so that the design supports the intended ownership structure from the outset.
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.
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.
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 Residential Design
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, careful air sealing, 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, the contractor relationship, and the level of guidance the client needs.
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 with the wider service scope rather than added as a generic final phase.
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.
