  • Your project deserves one team who owns it start to finish.

    Let’s Talk

    Planning, Architecture, Engineering,

    Under One Roof.

    You have land to develop, a project that’s stalled, or a design that’s outgrown your team. The usual path — a planner, then an engineer, then an architect, each waiting on the last — is how simple projects stall. Every hand-off is another place your file can sit, and another consultant who isn’t quite responsible for the whole thing.

    Our planners handle land severances, minor variances, rezonings, and Committee of Adjustment applications. For residential architecture, our BCIN designer takes

    townhouses, low-rise multi-unit buildings, and custom homes from first sketch to builder-ready drawings. Our OAA-licensed architect leads civic, institutional, commercial, industrial, and heritage restoration projects. Our structural and municipal engineers handle the structure and infrastructure behind it all.

    As a third-generation, family-run firm, we tell you what you need to know, not just what you want to hear.

    From concept to approval. One team.

    Nothing falls between firms – so your project keeps moving, and you’re not paying for the same conversation twice.

    Advantages

    The integrated model — planning, engineering, and architecture under one roof.

    Clients get one team, one point of contact — no coordination gaps or buck-passing between separate consultants, and projects don’t stall waiting for disciplines to talk to each other because they already are.

    Municipal insider knowledge that produces faster, better-prepared applications.

    Our team has worked inside municipal planning departments — they’ve been the reviewer and the approver, not just the applicant.

    No project outgrows the team.

    As a project grows in complexity, Vallee’s integrated team — planning, structural, civil, and architectural oversight — grows with it. Clients never have to switch firms.

    Brooke Hayward

    Chief Operating Officer | 214 Carson Co. Inc.

    “Vallee handled everything. Same reason I hire accountants and lawyers – I don’t have time to figure that out. They have all the answers to any objections that could come at them before they even present it. Worth every penny.”

    Tim Rodger

    Property Owner

    “I’ve been with Vallee for over a decade — planning, engineering, architecture, all of it. Their architects and designers design with builders in mind, not just custom homes, and that’s made a real difference.”
