Roncesvalles is one of Toronto's most active renovation markets, with a concentrated stock of early 20th century worker cottages, Victorian semis, and Edwardian detacheds undergoing full gut transformations. Kopman Build has been delivering these complex, character-sensitive renovations in the west end for over 25 years — with the discipline and transparency owners of these homes deserve.
Complete strip-to-structure renovations on Victorian and Edwardian semis and detacheds — new systems, new structure where needed, entirely rebuilt interiors.
Full kitchen remodels from layout changes to custom cabinetry, countertops, and appliance packages — designed to suit the character of older west-end homes.
Primary suites, main baths, ensuites, and powder rooms — complete gut-and-rebuild or targeted upgrades to aging plumbing and tile.
Expanding the footprint or height of smaller worker cottages and semis — designed to integrate with existing street character and zoning requirements.
Legal secondary suites, family rooms, and home offices built to Ontario Building Code — with particular attention to the foundation and waterproofing conditions common in pre-war Roncesvalles homes.
Sensitive restorations and renovations that preserve original brick, millwork, and character details while fully modernizing structure and building systems.

A full gut renovation on a Roncesvalles semi or worker cottage typically runs $350,000–$750,000+ depending on size, structural condition, and finish level. Kitchen-only renovations range $65,000–$160,000. Bathroom renovations run $28,000–$80,000. We provide detailed pre-construction estimates before any commitment so you understand the full number upfront.
Yes. Full gut renovations, structural modifications, additions, and basement conversions in Roncesvalles (City of Toronto jurisdiction) all require building permits. Many of these homes also fall within or near heritage conservation districts, which may require additional approvals. Kopman Build manages the entire permit process — applications, engineering consultants, heritage reviews, inspections, and final sign-offs.
Homes built in Roncesvalles between roughly 1900 and 1930 commonly present knob-and-tube wiring, galvanized plumbing, undersized foundations, balloon-frame construction, and deteriorated brick mortar. A thorough pre-construction investigation — which Kopman Build conducts before finalizing any scope or budget — identifies these conditions early so they are costed accurately and addressed properly during construction.
A full gut renovation on a two-storey Roncesvalles semi typically takes 10–18 months from permit issuance to occupancy, depending on scope and whether a rear addition or second-storey addition is included. Kitchen-only renovations run 8–14 weeks. Bathroom renovations 4–8 weeks. We build realistic schedules before construction starts and maintain open-book reporting throughout.
Yes. Rear additions and second-storey additions are among the most common projects in Roncesvalles as owners of smaller worker cottages and semis look to add living area rather than leave the neighbourhood. These projects require building permits, and rear additions may be subject to lot coverage and setback limitations under Toronto zoning by-laws. Kopman Build manages the full design-to-permit-to-construction process for additions of this type.
