Semmes & Co. Builders, Inc. has developed a New Custom Home program which focuses on building a team – with the realtor, architect/designer, outside consultants, and the owner.  Over the years we have found that by bringing all of the players together early in the process we can guarantee that everyone is working with a common design goal, budget and timeline. No one can speak to this better than our 100’s of satisfied clients.  Please request references and let them share their experiences.

Our services and management tools are designed to guide you through the process of building your dream home, from selecting the property and building site, through design, construction, and ultimately, move-in.


Semmes & Co. offers many services needed even before you are ready to start the design process. To help evaluate the feasibility of a development project, we offer Site Selection and Development Cost Consulting. Semmes & Co. can provide a review of what is allowed by the responsible municipality and the associated fees.  We can also help develop a preliminary design program – what you ultimately need and want in a new home, and provide costing, including rough costs for site development like grading and utilities.  Our staff understands that building a new home is the biggest investment of time and money that most people make.  We want to insure that your investment gives you the highest return possible and help you avoid the pitfalls of taking on a project that is not financially feasible or is not what you had hoped for.

Semmes & Co. also provides Environmental Building Systems Consulting services. Working with you and the design team, we can help develop a plan for sustainable building practices and technologies. We are familiar with the return on investment that various green building strategies provide, as well as with their impact on the health of your home.   Please see METHODS and RESOURCES for more information.


Our team-building commitment begins in Preconstruction.  It is in this phase that the layout, the design and finishes, and the long term energy use of your home are developed.  Semmes & Co. can provide different levels of support depending on the needs of your project.

We often work as part of an Architect-Builder Collaborative, wherein your architect completes architectural programming, preliminary design, and design development.  Semmes & Co. then provides development of the construction documents and management of the permitting process.  It is very important to Semmes & Co. and to the project that the architect continue to be part of the team during construction, both for periodic review and detail development.  This partnership works extremely well when working with an architect from out of the area, although we have also collaborated with many talented local architects and would be happy to provide referrals.

When working with an architect who is managing design, engineering and permitting, is critical that a project team be assembled and consulted early in the design process. Semmes & Co. can provide cost estimating and proactive value engineering solutions, assuring that the final design meets your expected budget.  We also provide years’ worth of building science and green building expertise to help make value and quality decisions on material and finish selections. This familiarity helps minimize surprise costs during construction and insure a positive experience for our clients.

If you have completed design and/or the permitting process and are searching for the right builder for your project – please don’t hesitate to contact us.  Semmes & Co. can bring many creative cost and energy efficiency solutions to the table, and complete cost estimating and scheduling for you.


Semmes & Co. provides a dedicated project team consisting of a project supervisor, production coordinator, and job manager as well as a staff of well-trained craftspeople. This project team is assigned during preconstruction and completes the Final Estimate, insuring our clients of a smooth transition into construction. To meet them, visit OUR TEAM.
