Licensed renovation contractors serving Midland and the surrounding Durham Region. Expert craftsmanship, free quotes, zero obligation.
When you love your Midland neighbourhood but need more space, a home addition or accessory dwelling unit (ADU) is often the smartest solution available. Whitby Renovation Services designs and builds home additions and ADUs across Midland that seamlessly extend your living space, add real estate value, and — in the case of ADUs — generate rental income that can significantly offset your renovation investment.
Heritage homes and waterfront properties — renovated with care in Midland. Our additions and ADU team has navigated Midland's planning approvals, zoning requirements, and building permit processes dozens of times.
A main-floor addition in Midland extends your home's footprint outward — adding a family room, larger kitchen, main-floor primary suite, or sunroom. Second-storey additions are ideal for Midland homeowners on lots with limited side or rear yard space. Both project types require structural engineering, foundation work, and careful integration with the existing roofline.
An ADU — whether a detached laneway house, garage conversion, or self-contained suite above an existing structure — is one of the highest-return investments a Midland property owner can make. ADUs can serve as rental income properties, multigenerational living spaces, or private home offices. We handle zoning pre-consultation, all building permit applications, structural design, mechanical rough-ins, and finish construction.
We serve all Midland neighbourhoods including Downtown Midland, Port McNicoll, Victoria Harbour, Georgian Bay Township and surrounding areas.
Adding square footage to your Midland home through a thoughtfully designed addition is often more cost-effective and emotionally satisfying than moving to a larger property. Our Midland additions team has designed and built main-floor extensions, second-storey additions, garage conversions, and standalone accessory dwelling units (ADUs) across Durham Region. Every addition project begins with a thorough assessment of your existing structure, lot coverage allowances, and zoning setback requirements under Midland's municipal planning regulations.
Second-storey additions are among the most complex residential construction projects we undertake in Midland. They require temporary weather protection for the existing structure during construction, careful integration with existing rooflines, and precise coordination between structural, mechanical, and finish trades. Our Midland additions team has the experience to manage this complexity efficiently — protecting your home and family throughout the process while delivering a result that looks as though it was part of the original design.
Accessory dwelling units (ADUs) are growing in popularity across Durham Region as homeowners respond to demand for rental income, multigenerational living arrangements, and work-from-home studio spaces. Our Midland ADU team is current on all relevant zoning permissions, Ontario Building Code requirements, and municipal approval processes — ensuring your ADU is permitted, inspected, and fully legal from the start.
Our additions process in Midland begins with a design-build consultation covering your goals, budget, and timeline. Our in-house design team then produces concept drawings and a preliminary budget for your review. Once the direction is set, we prepare full construction drawings, submit permit applications, and manage all approvals before breaking ground. Throughout construction, a dedicated project manager provides daily progress updates and coordinates all required municipal inspections.
Yes — all home additions in Midland require a building permit. This includes main-floor extensions, second-storey additions, garage conversions, and most ADU builds. Our team manages the complete permit application and inspection process as part of every addition project.
