Our Design-Build Services
We’re Toronto’s preferred premier contractor for residential design-build services. We also offer complete property maintenance as an add-on service following project completion, particularly for larger residential properties. Here’s an overview of our top-tier residential services:
Full Home Renovations
Client understanding is one of our top priorities from the start of every renovation. We make sure you have all the details, big and small, such as property utility capacity and zoning by-laws. We also offer assistance with service connections, builder’s risk insurance, and potential liabilities.
Home Additions
Each home addition includes drawings and layouts, material samples and shopping assistance, as well as options for budget-saving alternatives. Execution involves meticulous oversight, including protecting existing structures, dust control, and on-site project management. We use a CRM portal for progress tracking, with all trades uploading progress photos.
Basement Renovations
We handle basement finishing and renovation projects. This service includes on-site design consultations, project management, material sourcing, permit acquisition, and interior design. We work with licensed and experienced tradespeople to complete basement renovations skillfully with flawless execution.
Commercial Services
We specialize in high-end commercial interior renovation projects. This includes upscale condominiums, low-rise residential buildings, restaurants, hotels, offices, medical facilities, and gyms. We also offer optional 24/7 property maintenance services. The following is a detailed overview of our commercial services:
