When your current home no longer suits your needs, whether it’s lacking space, flow, or functionality, you’re faced with an important decision: should you build a new custom home or extensively renovate your existing one?
Both paths offer a route to a more personalized and functional living space, but they come with different timelines, budgets, and long-term impacts. The right choice depends on your priorities – whether that’s design freedom, cost, timing or long-term value. This guide explores the key considerations to help you confidently choose between building new or renovating based on your lifestyle, goals, and investment.
Key Considerations: Custom Home Build vs. Extensive Renovation
We’ve broken down the major decision points below so you can compare them side by side.
Personalization
New Custom Home:
You start with a blank canvas. A custom build gives you complete control over layout, materials, energy systems, and aesthetics, all tailored to your current and future lifestyle. However, this also means making more decisions throughout the process.
Renovation:
Renovations allow you to upgrade and reconfigure your space, but you’re still working within structural constraints, like existing layouts, ceiling heights, or foundation limits, which may compromise your vision.
Budget
New Custom Home:
A new build often involves higher upfront costs, but those costs are typically more predictable. You’ll also benefit from reduced maintenance, greater energy efficiency, and long-term cost savings.
Renovation:
Renovations may appear more cost-effective at first, but they often come with unexpected costs as issues behind walls or under floors are uncovered. These can easily lead to unexpected costs and escalation of financial commitment
Permitting & Zoning
New Custom Home:
New infill construction may require more extensive permitting and approvals, including compliance with current zoning bylaws. The process can be more complex and time-consuming.
Renovation:
Although permits can still be extensive, depending on the extent of the renovations, renovations may fall under less restrictive permitting and not trigger new zoning guidelines. This can lead to faster approval and more flexibility.
Timeline
New Custom Home:
A new build is generally seen as requiring more lengthy process. This can be partly due to the extensive design, permitting and planning process versus the actual construction. However, once construction starts, progress is more predictable.
Renovation:
Renovations may seem quicker, and they can be done in stages if you need to remain in the home. However, keep in mind that depending on the scope of work, the amount of time to carefully de-construct a home internally and rebuild can take as much, or even more, time and energy than to just demolish and start a new build.
Scope of Change
New Custom Home:
If you’re looking to make major foundational or layout changes, building new is often more practical and cost-effective. You’re not limited by the existing structure.
Renovation:
If the core layout of your home still works and your needs can be met with targeted updates, a renovation may be the smarter choice.
Property Value
New Custom Home:
New homes tend to have higher resale value, especially in growing or high-demand neighbourhoods. However, your design, neighbouring homes, and the risk of overbuilding may out-price the local market. Keep in mind, a new home will also increase property taxes.
Renovation:
Renovations may have a lower property value but if done right, it may preserve the character of the neighbourhood while being cost-effective in terms of re-sale. However, this likely won’t match the full market potential of a new build.
Structural Integrity & Energy Efficiency
New Custom Home:
New builds allow you to start with new and more advanced building methods, materials and systems, such as Insulated Concrete Forms (ICFs) which provide you enhanced durability, energy efficiency, and comfort.
Renovation:
You can improve energy performance in a renovation, but tying new systems to old infrastructure may limit what’s possible. Structural limitations and inefficiencies in older homes are hard to fully eliminate and may never match the performance of a new build.
Warranty
New Custom Home:
New builds are covered under Tarion, Ontario’s new home warranty program, which protects you against defects in materials and workmanship for up to 7 years.
Renovation:
Renovations are not covered under Tarion and are only backed by the contractor’s own policies or warranties, which can vary greatly.
So, Should You Renovate or Rebuild?
Choosing between an extensive renovation or a new custom home build comes down to your vision, timeline, and investment goals.
- Build new if you want full control, modern systems, maximum efficiency, and a long-term solution tailored to your lifestyle.
- Renovate if the home has character you want to preserve, the structure is sound, and your needs can be met with moderate changes.
If you’re leaning toward starting fresh, infill construction offers the opportunity to build your forever home with modern comforts, high-performance design, and no compromises.
