Hennessey Architecture.

We offer full architectural design services from sketching to high-performance buildings on any project type. Small or large, from kitchens to additions to homes, housing, hospitality, and retail projects- let's kickoff your project.

​

1. Proposal - We conduct an interview to understand your needs, wants, and goals. We will then provide a proposal for our scope of services.

2. Discovery - We visit your site, kickoff design conversations, and start sketching. We work with you to create a program for your building based on goals, your project site, and budget.

3. Schematic Design - We create early design concepts for how your project could look and feel. This looks like floor plans, elevations, and building massing.

4. Design Development - We refine the design with more detail on layout, materials, and building systems. The project becomes more specific on both the exterior and interior.

5. Construction Documents - We prepare detailed drawings the builder will use to get permits and build. We are getting closer to bringing your design alive.

6. Construction Administration - We check in during construction to be sure everything matches the design.

7. A Toast to You - We made it! Your project is ready enjoy. We are happy to help you celebrate with a small gift and a toast from the team.

​Passive House is a measurable building standard that creates a comfortable, high-performance, and cost-saving home built to last lifetimes. This standard is not just for homes but can be applied to all new construction and renovation projects. We achieve this through energy modeling software, analytics, and specifications before the structure is built. This is included as a basis to all new design projects, as an add-service for renovations, and as a consultant service for outside projects.

​
