Dual Porch Enclosure

Additional Project Details

Two adjoining homes, two porch enclosures, one build. D2 Build enclosed neighbouring front porches on a Danforth semi at the same time: shared framing, shared crew mobilization, and separate finish packages so each homeowner got the interior and exterior they wanted.

Two Porches, One Build

Danforth Semi-Detached Enclosures

The neighbours came to us with the same idea at the same time: close in the open front porches and get a year-round entry out of space that was only usable four months a year.

Building both at once made sense structurally and financially. One permit process, one set of scaffolding and crew mobilization, one material order across two units. The homeowners split the fixed costs that a single enclosure would have carried alone.

The bigger design decision was the brick. The original porches were carried on heavy masonry pillars that ate into an already narrow footprint. We reduced them to structural columns, recovering usable width on both sides without touching the load path. From there each homeowner made their own calls for siding profile, colour, window configuration, and interior millwork, so the two enclosures read as a pair from the street without being copies of each other.

Scope of Work

Before

Process

After

Structure & Envelope

  • Structural revision: Original brick porch pillars reduced to structural columns, freeing interior width on both units without altering the load path.
  • Framing: New stud walls across both porch openings, tied into the existing house structure, with rough openings for windows and exterior doors.
  • Insulation: Closed-cell spray foam in wall cavities and through the floor joists, with mineral wool batts and a sealed vapour barrier — a full thermal break from the previously open porch.
  • Air barrier: Tyvek HomeWrap installed and taped, with all window and door openings flashed and integrated to the WRB.
  • Windows & Doors: Black-framed windows and new exterior doors supplied and installed on each unit.

Interior Finishes & Carpentry

  • Wall assembly: Resilient channel over insulated framing for a flat, crack-resistant drywall surface.
  • Custom millwork: Each homeowner selected their own trim, casing, and built-in details — the two interiors were finished to separate specifications.
  • Drywall & Paint: New drywall taped, sanded, primed, and finished to each client’s colour and sheen selection.

Exterior Finishes & Electrical

  • Siding: Two different profiles and colours across the pair, selected independently by each homeowner.
  • Soffit, fascia & eavestrough: New throughout, integrated with the existing roofline.
  • Entry stairs: New front stairs and railings for each unit.
  • Electrical: Interior lighting and switching wired for both enclosures. Exterior fixtures reinstalled and new exterior outlets added

Two Neighbours, One Crew, Two Distinct Results

Building side-by-side porch enclosures at the same time gave both Danforth homeowners a shorter timeline, shared costs on permits and mobilization, and a front entry that still looks like their own.
