We used IDS for a bathroom design and rebuild about a year ago. We were very pleased with Kev's process, management and quality of delivery. When we moved to a condo earlier this year, we felt confident enough to hire IDS for a major overhaul of the condo, obviously a much bigger project. And our confidence was totally justified. The quality and thoroughness of the design (a gutted and completely rebuilt kitchen), the workmanship, the commitment to the planned schedule, the flexibility responding to new options during the work, the availability of Kev at all times - this is the standard of IDS. We are so grateful as we live in our condo that we only discover new examples of how well the design and workmanship were done. We cannot recommend this company highly enough.

IDS demolished a 3-piece bathroom in our house and rebuilt it from scratch. The project came in on schedule, and exactly as designed. Kev has a solid design sense and produced something modern and compatible with the rest of the house. Kev is a great planner, manages his trades effectively and also implements his plan as promised. We will certainly use this firm for any future renovation work we want done.

We completed the main floor remodel including the kitchen and enlarge the entire front porch deck. Kevork and the team were amazing. Their attention to detail and responsiveness made the project proceed smoothly, and now, approx 10 months after completion, we are very satisfied. The design achieved our goal of adding value and utility to our house, and there have been no issues whatsoever. We highly recommend Bianco Design & Build!

We are so happy with the work that IDS has done on our home. Everything from the design, to the work, to the friendliness and professionalism of the team has been exceptional. We were meeting with a few teams to get an idea of what we could do and Kevork arrived with ideas for the floor plan already drawn, how to optimize the space better, and examples/testimonials so we could visualize his other projects. Throughout the project he gave us renderings of the rooms, incorporated all of our feedback, came to choose materials with us and was very transparent about pricing and timelines. He was very organized, took our calls and answered emails very promptly and minimized the stress of the renovation. His team is great, all our neighbours commented on the professionalism of the team. Everyone who walks into our home is amazed by the level of craftsmanship and design details. We highly highly recommend IDS!

Kev helped us convert our basement into a legal second unit, and we greatly appreciated the work he and his team did. The project had its own set of obstacles, but Kev and his team managed to think of creative ways to overcome them. Kev was really patient with answering my questions regarding the project and he showed great people skills when it comes to communicating with city inspectors and other related parties. I would highly recommend IDS!

Kevork is polite and highly professional. He sent us 3D design of the bathroom, and after our approval the project was done within the agreed time line. They covered all areas with special protective film and kept the house clean during the whole renovation. The quality of finishing is very high which is quite rare these days! I am extremely happy with Kevork and am planning to her new projects with him soon!

Our Basement Renovation Process in Oshawa

Renovation planning and measuring tools

1

1. Consultation & Assessment

We start with an in-person visit to your home. We review the existing structure, assess current conditions, and take time to understand what you need the space to do, whether that’s a rental suite, a rec room, or a home office. This conversation shapes a project direction that’s realistic for your home and your goals.

2. Design, Planning & Permits

Once the scope is confirmed, we develop detailed drawings covering layout, framing, electrical, plumbing, and mechanical systems. Every finish and material is approved by you before work begins. We also manage all permit applications through the City of Oshawa on your behalf, coordinating required inspections and ensuring full compliance with the Ontario Building Code, so nothing holds up the build.

Frequently Asked Questions

What determines the cost of an Oshawa basement renovation?

The investment depends on the basement's square footage, the quality of finishes you choose, and the complexity of the plumbing or structural work required. Adding a full kitchen or a luxury bathroom will also impact the overall budget.

Are permits required for finishing a basement in Oshawa?

Yes, the City of Oshawa requires building permits for most basement renovations to ensure the safety and structural integrity of the home. We handle the entire application and inspection process for you.

How long will the construction process take?

While every project is unique, most Oshawa basement renovations are completed within 6 to 10 weeks. This timeframe accounts for framing, inspections, and final finishing touches like flooring and trim.

Can you help make my basement a legal rental suite?

Absolutely. We are well-versed in the specific requirements for legal secondary suites in Oshawa, including fire protection, soundproofing, and independent exit requirements.

How do you ensure the basement stays warm and dry?

We use modern waterproofing techniques and high-R-value insulation (such as spray foam) to create a thermal barrier. This prevents moisture buildup and ensures your basement feels as comfortable as your main floor year-round.
