Three Costly Renovation Mistakes to Avoid

Renovating your home is an exciting opportunity to create a space that better suits your lifestyle, adds value, and reflects your personal style. But without careful planning and expert guidance, renovations can quickly turn into stressful and expensive endeavours. At House of Three, we’ve seen how small missteps can lead to major headaches for homeowners across Ontario. 

Here are three common — and costly — renovation mistakes to avoid when planning your next project.

1. Skipping the Planning Stage

Jumping into a renovation without a clear plan is one of the biggest mistakes homeowners make. It’s tempting to visit a home renovation store, get inspired, and want to start picking out products and finishes right away—but it’s important to slow down and plan. Whether it’s a full home redesign, a basement suite, or a new kitchen, every successful renovation begins with a detailed plan. 

Without one, you risk going over budget, missing important structural considerations and permitting, and, ultimately, facing delays. Working with a BCIN-licensed designer ensures your project meets building code requirements and is well thought out from the start, helping you avoid costly changes down the line.

2. Not Considering Your Family’s Needs

Another common oversight is designing for today without thinking about tomorrow. Your home should adapt to your lifestyle, not the other way around. That includes everything from planning for a growing family to accommodating aging-in-place needs. Taking the time to assess your current and future requirements will result in a design that serves you longer — and saves you from another round of renovations in a few years.

3. Overlooking the Importance of Lighting

Lighting is often an afterthought in home renovations, but it can make or break a space. Poorly lit rooms, specifically offices may feel smaller, less functional, and less inviting. From natural light considerations in your layout to selecting the right combination of ambient, task, and accent lighting, good lighting design should be integrated from the beginning. It not only enhances your home’s aesthetics but also improves day-to-day comfort and energy efficiency.
