Home Additions & Space Upgrades

When an existing home no longer meets your family's needs, an addition is often more targeted than relocating. The real complexity lies in tying new framing into the existing structure while meeting zoning bylaws and building codes. Allera starts with an existing-condition review, plans the addition layout, coordinates engineering drawings and approvals, and manages critical construction interfaces.

WHAT WE DO

Scope of Services

Tailoring work scope and specialist engineering coordination around actual site conditions and project objectives.

Rear & Side Additions

Plan kitchen, living, or bedroom extensions based on rear yard depth, setback requirements, landscaping, and existing framing.

02

Second-Storey Additions & Layout Reconfiguration

Assess whether existing foundations and load-bearing framing can support an additional storey, coordinating stair, structural, and MEP modifications.

03

Basement Finishing & Interior Space Upgrades

Coordinate practical designs for basement finishing, functional zoning, natural light, separate entrances, moisture control, and life-safety compliance.

04

Laneway & Garden Suites

Evaluate detached accessory dwelling feasibility based on municipal bylaws, lot access, fire routes, tree protection, and utility servicing.

HOW WE WORK

How We Deliver

From initial briefing to site execution, we structure workflows around critical milestones—clarifying required documents, decisions, and coordination at every step.

Home Addition Project Showcase

01 | Site & Zoning Assessment

Review existing building conditions, lot dimensions, applicable zoning bylaws, and potential structural constraints upfront.

02 | Design & Required Approvals

Coordinate addition designs and engineering drawings; if minor variances or additional approvals are required, we map out submission requirements upfront.

03 | Structural Tie-In & Construction

Carefully manage structural openings, temporary shoring, waterproofing, insulation, MEP tie-ins, and neighbour impacts to minimize disruption.

KEY CONSIDERATIONS

Key Considerations

We focus not only on final aesthetics, but also on approval feasibility, smooth site execution, and long-term durability and maintenance.

  • Load-bearing capacity and foundation condition of the existing structure
  • Waterproofing, insulation continuity, and exterior cohesion between old and new
  • Site safety and phased construction sequencing for occupied homes
  • Site eligibility and servicing requirements for laneway and garden suites
Project Note

Permitted addition size, storeys, and eligibility for laneway or garden suites are subject to the specific property address, applicable municipal bylaws, and authority review.
