From an empty lot to the keys.

Scroll, and watch a building go up the way yours will — one phase at a time, with something in your hands at the end of each.

  1. Site & foundations

    Weeks 1–12

    Excavation, utilities and foundations. Before the first pour we lock the logistics plan: crane position, gates, deliveries and the neighbours’ hours.

    • Site logistics plan
    • Geotechnical sign-off
    • Updated cost report
  2. Structure

    Months 3–9

    Columns, beams and slabs climb a floor every eight to ten working days. Every pour is inspected and photographed before the next floor starts.

    • Weekly progress photos
    • Floor-by-floor inspection log
    • Look-ahead schedule
  3. Envelope

    Months 7–13

    Curtain wall, roofing and the first heat. Drying the building in early is what lets interiors start — so the façade is bought before the frame is finished.

    • Weathertight milestone
    • Envelope testing reports
    • Interior release by floor
  4. Interiors & handover

    Months 11–18

    Fit-out, commissioning and the punch list. We walk the building with your team before the inspector does, then hand over keys and a complete digital record.

    • Commissioning reports
    • As-built model and manuals
    • One-year warranty walk

Built, handed over, still standing.

What would it cost, and how long would it take?

The same square-foot ranges our preconstruction team starts from before there are drawings. Move the sliders; the building moves with them.
