Buildings, systems and repeatable development.

New buildings, additions and renovations. We specialise in mass timber and price a design while it can still change.

Algorithmic costing + design

See what a design change costs before you make it.

We model the site, the structure and the main building parts, each with an approximate cost.

Change a storey height or move the building, and the model shows how the cost responds, including the sudden jumps, like an extra row of footings or a bigger mechanical unit.

On one project, early modelling identified more than $1 million in potential construction savings.

Estimated construction cost
$2.48M
10,800 ft² · 3 × 2 bays · 2 storeys at 14 ft

More home.
Same land.

A new home above an existing house, on its own frame.

New columns and foundations beside the house carry the addition, so the house below stays in use. It starts as a one-storey loft and can grow to two. It works for a single home or across a portfolio of properties.

Regional field access

A small practice with a large practical radius.

DAO has its own aircraft for site visits, supplier meetings and construction review across Ontario. Same-day visits are possible across much of the province, weather permitting, which cuts travel time and cost on remote projects.

Flying range from DAO's Sudbury and Ottawa offices Map of Ontario and southern Quebec with rings at 200 and 400 kilometres around Sudbury and around Ottawa. The two offices are 426 kilometres apart in a straight line. Together the rings cover Toronto, Barrie, London, Kingston, North Bay, Timmins, Sault Ste. Marie and Montréal. 426 km · ~1.5 h Sudbury Ottawa Toronto Kingston London North Bay Timmins Sault Ste. Marie Montréal Québec City Barrie 200 km 400 km 200 km 400 km

Working with us

From first call to construction.

Most projects start with a short call and a look at the property. If the next step isn't clear, we start with a feasibility review.

  1. Property
  2. Planning
  3. Design
  4. Delivery
One project, start to finish. Illustrative.
  1. Property

    Site review, existing records, 3D scans and a map of the constraints.

  2. Planning

    Feasibility, rezoning, minor variances, site plan and other approvals.

  3. Design

    Concept options, cost modelling where useful, visualisation and documentation.

  4. Delivery

    Consultant coordination, building permit and construction administration.
