Why opt for a home addition?
If your home is bursting at the seams, you have two options:
- Move to a bigger property in a new location
- Extend the family home you know and love
Here’s how the two options stack up:
| Category | Building an Addition (Extension) | Moving to a New House |
|---|---|---|
| Direct Costs | Additions costs start from approx. $250 per sqft depending on the project finish and location. | Real estate commissions (typically 5% of sale price). |
| We offer free, no obligation, realistic estimates based on our extensive experience of building additions for homes in the Guelph area. | Land Transfer Taxes (between 1.5%–4% of purchase price). | |
| Expenses to travel to multiple house viewings. | ||
| Permits and Other Fees | City and local authority permits ($1k–$5k). | Legal fees ($1.5k–$3k). |
| Permit drawings, design schedule, project management fees, and more. | Surveys and compliance checks on any new property. | |
| Possible property tax reassessments. | Moving company fees ($1.5k–$4k). | |
| Surveys to check design is feasible (e.g. radon report). | Utility connection fees if required. | |
| New mortgage / loan fees. | ||
| Lifestyle Benefit | What you want, how you want it! You design the exact layout you need (e.g. specific home office or sunroom). | Possible need to remodel or reconfigure rooms. |
| No disruption to existing friendships, activities, schooling and work. | Possible better school options. | |
| A shorter commute? | ||
| New community to explore. | ||
| Stress Factors | Design build minimizes the stress as the contractors manage every aspect. | Stress of coordinating the sale of your old home with the purchase of a new one. |
| Possible minor disruption and noise during the day. | Time involved in both buying and selling. | |
| Time and hassle of packing/unpacking. | ||
| Disruption to children through potentially moving schools. | ||
| Community | Stay in your neighbourhood, keep your kids in their current schools, and close to their friends, sports team, etc. | Complete disruption to daily routine. |
| Stay in a community with all the support systems you know and enjoy, including grandparents. | New neighbours, possibly new schools, and the stress of finding new local services (doctors, gyms, etc.). | |
| Equity Impact | Potential high ROI (Return On Investment) as your addition will increases property value. | Money spent on moving costs require upfront equity that isn't recovered until the new home appreciates. |
It’s easy to see the advantages of a well-designed home addition as a highly cost effective way to add more space, especially with our stress-free design build process (link to design build page).
