What is the cost of construction?
Construction costs can vary significantly from one project to another, and cost per square foot is only a rough starting point. Two homes of the same size can have dramatically different construction costs depending on the complexity of the design, quality of finishes, amount of glass, structural requirements, site conditions, and how the project is built.
In our experience, some of the biggest factors affecting construction cost include design complexity, finish level, site development, project size, and contractor involvement. A straightforward home using standard materials and conventional construction methods may cost substantially less per square foot than a highly customized home with large expanses of glass, complex structure, premium finishes, or challenging site work.
Site conditions can be particularly significant. Steep slopes, retaining walls, difficult excavation, high snow loads, limited site access, or extensive utility work can add substantial cost without adding any additional square footage to the home. Similarly, additions and smaller projects often have a higher cost per square foot than larger new homes because kitchens, bathrooms, structural modifications, and other expensive components are concentrated into a smaller area.
The way a project is constructed also matters. An owner who acts as their own general contractor or performs portions of the work themselves may achieve a very different construction cost than a comparable project completed by a full-service custom home builder.
For these reasons, we prefer to evaluate construction budgets based on the specific project rather than applying a single cost-per-square-foot number. Early in the design process, we consider the project's size, complexity, site, material expectations, and construction approach to help establish a realistic budget and design accordingly.
