Modern Residential Architecture and Design in Toronto
Residential Design for Custom Homes, Renovations, and Multiplexes
baukultur/ca is a Toronto residential design studio creating custom homes, major renovations and additions, multiplexes, laneway houses, and garden suites across Toronto and the GTA.
Many clients come to us before the project is defined. They may be deciding whether to renovate or rebuild, add space or create a second home, develop a multiplex, or phase the work over time. We assess the property, compare viable options, identify likely approvals, and show how each path affects cost, timing, construction, and long-term use.
Once a direction is chosen, we develop the architecture, interiors, building performance, permit work, consultant coordination, and construction decisions together. Founder and principal designer Felix Leicher remains directly involved through design, approvals, and construction.

Define the Project Before Committing to It
The same Toronto property may support several realistic options. A house could be renovated, enlarged, replaced, converted to multiple units, or paired with a laneway house or garden suite. Zoning is only one part of the decision.
Existing conditions, trees, ravine restrictions, servicing, structure, financing, family plans, rental goals, timing, and construction disruption can change which option makes sense. Feasibility brings these factors together before significant time and money are committed.
The result is a defined scope, a realistic approval path, and a sound basis for design.
Different Residential Projects Require Different Decisions
Custom Homes
A custom home begins with the property: orientation, views, privacy, street presence, garden connection, zoning, and budget. These conditions establish the size, organization, massing, and relationship to the site before the structure, interiors, materials, and building systems are developed.
Room proportions, daylight, privacy, circulation, and material choices are developed from the property and the household's priorities rather than treated as separate decisions.
Major Renovations and Additions
The first decision is what should remain, what should change, and where new construction adds enough value to justify its cost. Existing structure, room proportions, building code, mechanical systems, construction sequencing, and the character of the house all affect that answer.
New work is designed around what is worth retaining, improving daylight, circulation, comfort, energy performance, and the relationship to the garden.
Multiplexes
A multiplex must resolve more than unit count. Each household needs daylight, privacy, storage, acoustic separation, efficient circulation, outdoor space, and a clear entrance.
baukultur/ca designs duplexes, triplexes, fourplexes, and other small multi-unit buildings for owner-occupiers, multi-generational families, groups building together, and boutique residential developers. Ownership, rental strategy, financing, servicing, structure, and future flexibility are considered before the unit layouts are fixed.
Laneway Houses and Garden Suites
Laneway houses and garden suites can create rental income, support family members, enable aging in place, or add a flexible second home.
On compact Toronto properties, emergency access, trees, servicing, privacy, parking, and the relationship to the main house establish the limits of the project. Daylight, storage, circulation, and outdoor space determine whether the secondary home feels complete rather than residual.
Proof in Completed Work
Since 2015, baukultur/ca has completed more than 150 residential projects across Toronto and the GTA.
At zero79, two independent three-storey homes, each with a finished basement, were placed on a standard 25-foot Toronto infill lot. The project shows how early decisions about ownership, access, massing, privacy, outdoor space, and approvals can turn a constrained property into two complete homes.
Architecture, Interiors, and Building Performance Developed Together
Plans, structure, mechanical systems, materials, and details are developed together because a change in one affects the others. This protects the quality of the rooms and reduces conflicts that would otherwise emerge later.
Space, Structure, and Site
Room proportions affect daylight, furniture, circulation, and structure. Window positions determine views and privacy while also affecting the building envelope and interior layout. A stair can organize the plan, bring light into the centre of the house, and provide storage.
These relationships are resolved while they can still be changed without costly rework.
Interiors and the Details of Daily Use
Interior design begins with the plan, not after it. Kitchens, millwork, storage, lighting, fixtures, finishes, and material transitions are developed alongside the architecture.
A built-in can divide space and provide storage. A change in material can clarify circulation. A carefully placed opening can connect rooms while preserving privacy. Together, these decisions connect the overall plan to the details used every day.

Comfort, Durability, and Energy Use
Orientation, insulation, windows, air sealing, ventilation, heating and cooling, low-VOC materials, and future adaptability are considered with the design and budget.
Some projects pursue Passive House-informed, Net Zero, or all-electric strategies. Others focus on targeted upgrades to an existing house. The appropriate level of performance depends on the property, existing conditions, scope, and budget. The objective is better comfort, healthier indoor air, greater durability, and lower energy use without separating performance from the rest of the design.
Selected Residential Projects in Toronto
The projects below show different responses to Toronto properties, households, and housing goals—from custom homes and major renovations to multiplexes and compact secondary homes.
From Feasibility Through Construction
Feasibility and Project Definition
We document existing conditions, review planning and zoning constraints, identify likely approvals, test broad options, and establish the project scope. Major assumptions are tested here, before the design is advanced.
Design, Approvals, and Consultant Coordination
Schematic design develops the plan, massing, circulation, and relationship to the site. Design development resolves structure, interiors, building systems, materials, and key details. Permit and approval work is coordinated with the consultants required for the project.
Clients can see what is being decided, why it matters, and what follows.
Pricing and Construction
During pricing and construction, we can coordinate contractors, respond to site questions, review pricing and invoices, assess proposed changes, prepare material and fixture selections, conduct site reviews, and resolve design and construction issues.
The scope is tailored to the client. Some clients want to take part in every discussion and selection. Others prefer us to prepare recommendations and bring forward only the decisions that require their approval. With comprehensive involvement, the client’s role can be reduced largely to approving key decisions and authorizing payments.
Site decisions, substitutions, and changes are assessed against the priorities established earlier rather than treated as isolated choices.
Common Questions at the
Start
Should We Renovate, Add, or Rebuild?
We compare the condition and potential of the existing house with zoning, approval requirements, construction cost, disruption, timing, and long-term use. The answer depends on the property and the client’s priorities, not on a general preference for renovation or new construction.
Can the Property Support a Multiplex, Laneway House, or Garden Suite?
We review lot dimensions, zoning, access, trees, servicing, parking, existing buildings, and likely municipal approvals. This establishes what can fit, what can be approved, and whether the project supports the client’s ownership, family, or rental goals.
How Involved Do We Need to Be During Construction?
Clients choose the level of involvement they want. Some remain closely engaged. Others prefer baukultur/ca to coordinate the work, prepare recommendations, review costs and changes, and present the key decisions for approval.
Direct Experience Across Design, Approvals, and Construction
Since 2015, baukultur/ca has completed more than 150 residential projects across Toronto and the GTA, including custom homes, renovations and additions, multiplexes, laneway houses, and garden suites.
Felix Leicher brings experience in architectural design, construction management, and project delivery in Canada and Europe. That experience matters when design decisions affect approvals, consultant coordination, pricing, sequencing, and work on site.
baukultur/ca is intentionally small. Clients work directly with Felix from the first property review through design, approvals, pricing, and construction. This provides a consistent point of contact and reduces handoffs between the early idea and the built work.
