About

Built with purpose.
Designed to last.

Hart Structures builds and renovates homes with the care an architect gives a drawing — attention to structure, materials, craftsmanship and the people who live there.

Founded by a licensed structural engineer and a civil engineer, we take a project from first assessment to final walkthrough: structural design, permits, trades and finishes under one team. Good construction starts with good planning, and a space is only finished when it works for the life that happens inside it.

VISION

Every project begins on paper. We read the structure before we touch it, so the plan is honest about what the building can become.

CRAFT

Concrete, terrazzo, timber and steel, detailed with precision. The finish is where engineering becomes something you can touch.

PEOPLE

We design around the family, not the floor plan — clear communication with homeowners from scope to handover.

LASTING IMPACT

Safe, efficient, constructible structures, built to code and built to age well — spaces that keep working for decades.

What We Do

From structure
to surface.

    Material Library

    to surface.

    Process

    Drawing to doorway.

    Four stages, one team, and a clear record of every decision along the way.

    01

    DISCOVER

    Site visit, assessment of the existing structure, scope and feasibility, and an honest budget range.

    02

    DESIGN

    Layout, structural design, engineering drawings and permit documents — with material and finish selection.

    03

    BUILD

    Trades, schedule and budget coordinated on site, with quality checked against the drawings at every stage.

    04

    DELIVER

    Final walkthrough, documentation handed over, and a space ready for the life that happens inside it.

    People

    Engineers who build.

    Two co-founders: one designs the structure, the other makes sure it gets built right.
