Service FAQs
Common questions about commercial interior design-build, tenant improvements, and permit coordination.
Do you work with shell units and landlord base-building requirements?
Yes. We review the base-building conditions, coordinate required drawings, and plan the build-out to meet landlord and code requirements.
Can you support permit approvals?
We support submissions by coordinating documentation with your design team and responding to municipal review comments to keep approvals progressing.
What project types do you take on?
Restaurants and cafés, medical clinics, pharmacies, professional offices, daycare, and light industrial interiors across the GTA and Ontario.
How do you handle budgeting and changes?
We provide early budgets and alternates, then track scope and pricing so decisions are documented and impacts are clear before work proceeds.
What is your typical timeline?
Timelines vary by scope and approvals. After an initial walkthrough, we provide a schedule aligned to procurement, inspections, and turnover requirements.
Do you provide pricing online?
Because every space and scope is different, we quote based on drawings and a site review. Request a consultation for a tailored estimate.
