Frequently Asked Questions

Most families can remain in their homes during portions of the construction process. However, temporary relocation is typically necessary for 3-4 weeks during roof removal and major structural work. We minimize disruption through:

• Creating contained work zones with sealed barriers
• Installing temporary dust walls and air filtration
• Maintaining essential services throughout construction
• Establishing clear work hours (typically 7:30 am-5:00 pm weekdays)
• Regular site cleaning and debris management

Our project managers develop customized plans based on your family’s needs and schedule, ensuring comfort and safety throughout the construction process.  

Yes, most homeowners remain in their homes throughout construction. We create effective separation through:

• Temporary dust walls with sealed barriers

For kitchen expansions, we set up temporary facilities in another part of your home. Our project managers develop customized plans based on your family’s specific needs and schedule.

In Toronto’s current market, these additions offer significant value enhancement:

• Immediate property value increase: 80-90% of the construction cost
• Rental income potential: $2,500-$3,500 monthly for premium units in desirable neighbourhoods
• Increased buyer appeal: Properties with legal secondary suites typically sell 20-25% faster

In neighbourhoods like Forest Hill and Rosedale, high-quality suites that match the architectural character of the main residence deliver the highest returns.

We create seamless integration through:

• Exterior harmony: Matching or complementary materials, proportions, and architectural details
• Interior transitions: Consistent flooring, millwork, and design elements
• Structural integration: Careful engineering that preserves architectural integrity
• System coordination: Seamless mechanical, electrical, and plumbing connections

Our integrated design-build approach ensures all teams collaborate from the earliest stages, resulting in expansions that feel like original features of your home.

You’ll never receive surprise charges without prior discussion and approval. Our integrated design-build approach allows us to quickly develop and implement solutions that minimize delays. Our proactive approach includes:

• Thorough pre-construction investigation of existing conditions

Rear and side expansions offer distinct benefits that make them ideal for many Toronto homes:

• Stay in your home throughout most of the construction process
• Preserve street presence and curb appeal, particularly valuable in heritage neighbourhoods
• Create seamless indoor-outdoor connections through large sliding doors or folding wall systems
• Face fewer height restriction challenges than vertical additions, often resulting in simpler approvals
• Maximize natural light through strategic window placement on multiple sides
• Ideal for open-concept living spaces that connect to the garden or outdoor areas

A second-floor addition offers several advantages over relocating:

Financial benefits:

• Avoid land transfer taxes (which can exceed $100,000 for luxury properties)
• Eliminate real estate commissions (typically 5% of sale price)
• Build equity rather than starting fresh with a new mortgage
• Typically return 70-85% of the cost immediately in increased property value

Lifestyle advantages:

• Remain in your established neighbourhood with schools and amenities you value
• Create exactly the space you need, tailored to your family
• Preserve your valuable yard space (unlike ground-level additions)
• Gain better views and increased natural light with upper-floor living spaces

For Toronto’s premium neighbourhoods, where available housing inventory is limited, additions often provide the only practical way to gain needed space while staying in your desired location.
