The architect
The architect translates the homeowner's program, site, aesthetic goals, and applicable requirements into a coordinated design. Depending on the agreement, the architect may also help obtain approvals, review submittals, visit the site, evaluate payment applications, and administer the construction contract.
The architect protects design intent, but is not typically responsible for the contractor's means and methods, daily supervision, or the owner's entire financial and decision-management system.
The builder
The builder is responsible for planning and executing the construction scope under the building contract. That includes field supervision, trade coordination, procurement, schedule management, cost administration, quality control, and completion of the work.
On a custom home, the builder also turns drawings and selections into coordinated field decisions. The best results come when questions are raised early and the design team has time to respond before work is covered or materials are fabricated.
The interior designer
The interior designer develops the material, furnishing, lighting, millwork, and experiential layers of the home within the agreed scope. Their information must connect to architectural documents, purchasing, lead times, and construction sequencing.
Clear responsibility for specifications, approvals, purchasing, storage, installation, and damage prevents avoidable gaps between design and construction.
The owner's representative
The owner's representative works for the homeowner and looks across the project rather than through a single professional discipline. The representative helps the owner assess information, track priorities and decisions, monitor budget and schedule, and follow unresolved issues.
The role should complement the architect and builder, not create a second command structure. A good representative strengthens communication, respects contractual boundaries, and makes the owner's approvals more informed and timely.
How the team works together
At the start, the team should define who prepares information, who reviews it, who approves it, and when the decision is needed. The same clarity should cover meetings, site reports, requests for information, submittals, samples, changes, payments, and closeout.
- One current source for drawings, specifications, selections, and meeting records
- A decision log with due dates and cost or schedule implications
- A transparent change process before additional work proceeds
- Regular reporting that distinguishes facts, risks, choices, and required action
