Design, Engineer & Build Under One Roof

divider

Total Renovations is a licensed residential contractor and experienced home addition company delivering complete additions since 2011. As your single home addition contractor, we manage every stage — design, structural engineering, foundation, framing, roofing, plumbing, electrical, insulation, finishing, permits, and inspections — under one fixed price with one dedicated project manager.

Every existing home responds differently to an addition. Bungalows, split-level homes, character houses, newer builds, and acreage properties each have different foundations, framing systems, rooflines, and service requirements. That is why structural assessment, careful design, and experienced coordination matter before construction begins.

Whether you need a single-room bump-out, a larger main-floor extension, an in-law suite, a garage-top addition, or a full second-storey transformation, Total Renovations delivers the same fixed-price accountability and structural rigour on every project. We plan the addition around your home, your goals, and your budget, then coordinate every trade through final inspection.

Complete Home Addition Services
Designed Around Your Home

Total Renovations provides every home addition service you need — design, engineering, foundation, framing, roofing, mechanical systems, interior finishing, permits, and inspections — all managed under one roof, one fixed price, and one dedicated project manager.

room additions
Room Additions
Room additions create the exact space your family is missing — an extra bedroom, larger family room, main-floor primary suite, home office, dining area, or expanded kitchen. We handle foundation, framing, roof tie-in, utilities, insulation, and full interior finishing so the new room feels original to the house.
second story additions
Second-Storey Additions
A second-storey addition can add bedrooms, bathrooms, a primary suite, office space, or an entire new living level without reducing yard space. We assess and reinforce the existing foundation and structure, engineer the new floor system, manage temporary weather protection during roof removal, and complete the upper level under one fixed-price contract.
home extensions
Home Extensions
Rear and side home extensions expand the main floor outward — extending a kitchen, creating a great room, adding a dining area, or building a main-floor suite. We manage design, foundations, structural tie-ins, roof integration, services, zoning review, and permits under one fixed price.
custom home additions
Custom Home Additions
Custom home additions are designed around how your family lives. Options include multi-room additions, combined ground-floor and second-storey builds, vaulted great rooms, accessible main-floor suites, and additions integrated with kitchen or whole-home renovations. We coordinate architecture, engineering, trades, finishes, and inspections so the completed space looks and feels original to the home.
farmhouse acreage additions
Character & Existing-Home Additions
Older homes, character houses, bungalows, and split-level properties require additions that respect the original structure and architecture. We design compatible rooflines, exterior materials, window proportions, and interior transitions while upgrading structure, insulation, utilities, and layout for modern living.
in law suite coach house additions
In-Law Suite & Coach House Additions
We build fully permitted in-law suites, multi-generational additions, and coach house additions where the property and local regulations allow. Projects can include separate entrances, kitchens, bathrooms, accessible features, independent heating, and required fire separation — adding flexible living space for family or potential rental use.
garage shop top additions
Garage & Garage-Top Additions
Adding an attached garage, workshop, or living space above a new or existing garage is a practical way to expand your property. We design and build garage-top bedrooms, offices, studios, and suites, coordinating foundations, structure, fire separation, access, and services so the addition integrates cleanly with the home.
sunroom great room additions
Sunroom & Great Room Additions
A four-season sunroom or vaulted great room can bring in natural light and create a spacious connection between indoor and outdoor living. We build insulated, code-compliant additions with large glazing, proper heating and cooling, durable foundations, and seamless access to the existing home.
foundation structural engineering
Foundation, Structural & Engineering
Every home addition depends on sound structure. We coordinate geotechnical and structural engineering where required, build new foundations and footings, reinforce existing framing for added loads, and manage beams, posts, shear walls, roof connections, and load paths under permit. This structural rigour helps the addition perform reliably for decades.

How Your Home Addition Works
Our 4-Step Process
divider

Every home addition follows our proven 4-step process, designed to deliver the finished space on schedule, on budget, and to the agreed specification with clear communication from consultation through final inspection:

1.
Free In-Home Consultation
We visit your home, assess the existing structure, lot, foundation, access, and utility requirements, review applicable zoning constraints, discuss your goals, and provide honest guidance on scope and budget. No sales pressure and no obligation.
2.
Design, Engineering & Fixed-Price Quote
We produce addition drawings, coordinate structural engineering, and deliver a comprehensive fixed-price quote covering foundation, framing, trades, finishes, and permits. You see the plan before you commit, and the number we quote is the number you pay.
3.
Permit Application & Trade Coordination
We prepare and submit the required permit applications, schedule inspections, and coordinate every subtrade — excavation, foundation, framing, roofing, plumbing, electrical, HVAC, insulation, and finishing — under one project manager.
4.
Construction & Final Inspection
Your home addition is built to the agreed specification and schedule, with weather protection managed throughout. We walk through the finished space with you, address any deficiencies immediately, obtain final occupancy approval, and hand over your completed addition.
Why Home Addition Planning Matters — Structure, Design & Long-Term Value

A successful home addition must connect new construction to an existing building without creating structural, moisture, comfort, or design problems. Foundations, framing, rooflines, drainage, insulation, heating, electrical capacity, and interior circulation all need to work as one system.

Good design starts with how your family will use the space. We study room relationships, natural light, privacy, access, storage, furniture placement, and future needs before finalizing the footprint. The exterior is planned with compatible massing, roof form, windows, and materials so the addition enhances rather than overwhelms the original home.

Before design is completed, we review the property constraints that can affect buildable area, including setbacks, lot coverage, height, servicing, access, drainage, and structural conditions. This early due diligence reduces redesign, permit delays, and unexpected construction costs while protecting the long-term value of the investment.

Home Addition Permits — What You Need to Know
Home additions normally require building permits for structural and foundation work and may also require plumbing, electrical, mechanical, development, or zoning approvals. Total Renovations coordinates drawings, engineering, applications, and inspections so the approval process stays connected to the construction plan.
Building & Trade Permits
Building permits are typically required for the addition itself, while plumbing, electrical, gas, and mechanical work may require separate trade permits. We identify the required approvals, prepare the submission package, and coordinate inspections throughout construction.
Existing-Home Structure
Connecting new construction to an existing home requires careful review of foundations, framing, roof systems, lateral resistance, and load paths. We coordinate the required engineering so the addition is safe, durable, and code-compliant.
Secondary Suites & Accessory Spaces
Secondary suites, coach houses, and accessory living spaces are subject to property eligibility, size, siting, servicing, parking, access, and fire-separation rules. We confirm feasibility before design and manage the required approvals.
Floor Area Ratio & Lot Coverage
Every addition must respect applicable floor area, lot coverage, height, and setback limits. We confirm what the property allows before design is finalized and identify whether a variance or additional approval may be needed.
Structural Engineering
Second story additions and larger ground-floor additions require a structural engineer's design for foundations, floor systems, and load paths. We coordinate all engineering and submit stamped drawings as part of the permit package.
Site, Grade & Drainage
Sloped sites, poor soils, limited access, high water tables, and drainage conditions can affect foundation design and construction sequencing. We coordinate site review and supporting engineering where required.
