Three factors drive the investment in a major residential project: size, complexity, and quality of finishes. Define them together, before the architectural plans are underway, and you can adjust square footage or architectural features to protect the finish level you actually want. Define them separately, or late, and you’re left with a gap that’s hard to close.
The owner of a furniture company came to us after the fact. The plans were done. A builder was already on board and scheduled to demolish the home on the lot acquired for the new build. The architect had designed exactly what the property owner and his wife asked for, and designed it well. But nobody had looked at what that design would take to build.
The builder worked from the finished plans and quoted a baseline per-square-foot figure. That number leaned on allowances: placeholder line items for finishes, fixtures, and equipment, set at a quality that did not match the level the owners expected to live with.
The gap between what he wanted and what that number assumed was too wide to close. He’d done plenty of planning, the architectural kind. What nobody had offered him was a plan for the investment itself.
That’s the step most residential projects skip, and it decides whether everything after it holds, or becomes a series of compromises, change orders, and delays.
Three Factors, Not One
Whether it’s a ground-up custom home or a major renovation, the investment comes down to three factors. All three need to be defined early, and together, not discovered one at a time as the project moves along.
Size. Square footage, number of bathrooms, the footprint of the kitchen. It’s the most visible lever, and the one most owners already have a feel for.
Complexity. How intricate the design and engineering really are: open-concept spans, a waterfront lot, structural changes to an existing home. Two homes with the same square footage can call for very different investments depending on what the architecture asks of the structure.
Quality of finishes. Millwork, cabinetry, tile, lighting, plumbing fixtures, appliances: what you touch and feel every day. The level of custom millwork and finishes can shift the investment significantly, and it’s usually the lever left undefined until a builder’s quote forces the question.
Each one matters on its own. Where projects go sideways is when one or two get defined early and the third gets assumed, usually finishes, because they’re the hardest to picture from a set of architectural drawings.
The Trade-Off That’s Easy to Miss
Picture a home with striking architecture outside and builder-grade finishes inside. The exterior looks distinctive. The interior doesn’t. If the investment is a real constraint, it’s usually better, for resale and for how the house feels to live in, to reduce square footage than to end up with finishes you’ll regret every day.
But that trade-off only exists early. Once the architectural plans are finished and a builder is pricing them, the conversation about square footage or architectural features has mostly closed. What’s left is deciding how much of an investment is necessary, or which finishes to cut or lower the quality on.
Where This Project Could Have Gone Differently
If we’d been in the room while those plans were still taking shape, the conversation would have sounded different. Not smaller ambitions, just a real trade-off: which architectural features could flex so the finish level the owners wanted stayed within reach.
A capable builder can sometimes make that trade-off work too, but in our experience, few do. Most are quoting to a finished set of plans, not advising on them, and when finish-driven increases show up later, they tend to land on the interior design side of the ledger instead of the builder’s.
That’s why we treat architectural planning, finish level, and construction complexity as one conversation, starting at the first planning meeting, not after the drawings are done. It’s the core of our Design Execution Framework™, and it begins with the Project Roadmap™ Phase, where size, complexity, and finish level get resolved together before plans are final. Before that, a Feasibility Brief gives you a documented read on what your property will support, so design doesn’t start moving in a direction the investment can’t follow.
Questions Homeowners Ask
What factors drive the investment in a major residential project?
Three factors shape it: size (square footage, number of bathrooms, kitchen footprint), complexity (architectural detail, structural changes, site conditions), and quality of finishes (millwork, cabinetry, tile, lighting, plumbing fixtures, and appliances). All three should be defined early and together.
Why do finishes affect the investment so much?
The amount of custom millwork and cabinetry, and the level of finishes, fixtures, and equipment, can shift the investment significantly. They’re also the hardest to picture from architectural drawings, so they’re often left undefined until a builder’s quote forces the question.
What happens if the finish level isn’t defined before plans are final?
A builder prices the plans using assumptions, often allowances set at builder-grade quality. If that number doesn’t match the finish level the owner expects, the gap can be hard to close, and by then the chance to adjust square footage or architectural features has largely passed.
If the investment is limited, is it better to reduce square footage or compromise on finishes?
If the investment is a real constraint, it’s usually better, for resale and for daily living, to reduce square footage than to end up with finishes you’ll regret. That trade-off is only practical early, before the architectural plans are finished.
When should size, complexity, and finish level be planned together?
At the first pre-construction planning meeting, before the architectural drawings begin. At STUDIO 818, that happens in the Project Roadmap Phase of the Design Execution Framework, following a Feasibility Brief on the specific property.
