Design-build Ottawa
One team from first drawing to final walkthrough.
Design-build is a way of delivering a renovation or construction project under one agreement. Instead of hiring a designer first and then tendering the drawings to builders, design and construction are coordinated together — so cost, schedule and buildability shape the design while it is still easy to change.
01
One point of contact
Design questions and construction questions go to the same team.
02
Pricing during design
Cost input arrives while drawings develop, not after they are finished.
03
Fewer hand-offs
Permits, procurement and site planning can be prepared alongside design.
07 / Before the first finish
Plan the work around the space.
For a commercial renovation, the scope begins with more than finishes. Operations, occupied areas, deliveries, access windows and landlord requirements can all influence how the work is defined and sequenced. Typical examples include office renovations, tenant fit-ups, retail renovations, restaurant renovations and medical clinic renovations, as well as occupied commercial renovations scheduled after hours.
The same discipline applies to residential work. Existing conditions, selections and dependencies need to be visible so a proposal can be understood on more than the total price. That applies equally to kitchen renovations, bathroom renovations, basement renovations and whole-home renovations, and to work that needs a building permit under the Ontario Building Code.

The decisions
behind the finish.
An illustrative planning story. These images are not GCO project evidence.
01 / Scope
Start with how the business uses the space.
In this illustrative commercial plan, intended use, layout, occupied areas and service requirements would be reviewed together before defining the included work.
02 / Site
Consider the space around the work.
Access, existing conditions, deliveries, neighbouring uses and occupation requirements can change the sequence. This example highlights questions to resolve rather than assuming a business can remain fully operational.
03 / Finish
Define what completion means.
The final review should refer back to the agreed scope. Outstanding items, applicable documents and handover arrangements need to be understood before the work begins.
09 / How the project stays clear
Know what happens next.
From the first questions to the final review, understand the decisions at each stage.
01
Discuss
Start with the goals, the property and the timing. Identify what needs review before a proposal.
02
Define
Review the site, scope, assumptions and selections so the proposed work is understandable.
03
Coordinate
Consider the sequence, trades, access and decisions that influence the work.
04
Complete
Agree how the finished work, outstanding items and applicable documents will be reviewed.
10 / A considered choice
Know who you’re working with.
Choosing a contractor means choosing a working relationship. Ask who will manage the project, how specialist work is coordinated, and which decisions need your input.
A useful first conversation should leave you clearer about the project, not pressured to decide before the important questions are answered.
