McPhee Associates staffs an expert team of architectural designers with years of experience in residential architectural design on Cape Cod. Whether it’s a home addition, remodel, or new build, our design team combines technical training, creative skill, and deep local knowledge to bring your vision to life. We’re well-versed in a range of architectural styles, from classic Cape Cod home architecture to modern coastal design, ensuring every project reflects your unique taste and lifestyle.
As both a design and build company, we provide a streamlined, integrated process from concept to construction. Our in-house architectural design services include custom house plans, detailed 3D renderings, and full coordination through permitting and construction. This unified approach ensures consistency in quality, communication, and craftsmanship throughout every phase of your project.
Our team also understands the complexities of local zoning, building codes, and site-specific design on Cape Cod. This expertise allows us to anticipate challenges early in the planning process, saving time and supporting the best possible design outcomes.
We take pride in collaborating closely with our clients from the initial meeting to the final construction drawings, ensuring every design element reflects their lifestyle and goals. As a full-service design-build firm, our integrated approach allows us to offer a true one-stop-shop experience, with a seamless transition from design into construction. The result is a custom home or remodel that’s both beautiful and built to last.
Our Architectural Design Services
We provide full-service residential architectural design for new builds, renovations, and additions throughout Cape Cod. Our services include:
- Custom house plans and architecture plans
- Concept development and schematic layouts, 3D renderings and architectural visualizations
- Interior architecture and space planning

- Coordination with engineers, surveyors, and permitting officials
Every plan is developed to reflect your lifestyle, property, and aesthetic goals, whether coastal, traditional, or modern architecture.
Architect Collaborations
While some clients prefer designing and building under one roof, others prefer working with a separate architectural firm. Over the years, we’ve built long-standing relationships with esteemed architectural firms. A client will bring us in as the builder, or the architect will recommend us. Either way, it ultimately allows us to best suit the client’s needs.
We welcome the opportunity to collaborate with architects. Because we are custom home builders, our extensive experience with zoning and permitting challenges can be advantageous during pre-construction.
If you are an architect looking to partner with a quality builder, we’d love to discuss your project with you and share our industry knowledge.

Our In-House Architectural Design Process
For new custom home builds, we’ll visit the site to assess the natural characteristics of your property’s location and surroundings, making initial recommendations. During this process, we carefully note any apparent limitations.
For home addition and renovation projects, we’ll measure the existing home and gather any available site or original floor plans.
During our initial meeting, we’ll discuss your design objectives, including home style, room requirements, and lifestyle needs. Additionally, we’ll explore your outdoor living space preferences and any other items on your wish list. With this, we’ll create a design outline, which, upon approval, serves as the starting point for design work.
We’ll recommend a local site (or civil) engineer as needed, and coordinate on your behalf. This contracted engineer will gather data on the elevation of the property and any natural or man-made features.
With this approach, they’ll create an existing plan outlining topography, zoning details, and site coverage. This plan will serve as the starting parameters for the design process.
With the design outline and engineering plans in hand, we’ll measure your site and existing home to draw the as-built plans and elevations. This is the starting point for us to create proposed floor plans and elevations for all renovation and addition work. These plans will be provided for your initial review.
We’ll then work with you to analyze the proposed plans, collecting your feedback and thoughts. We’ll make revisions until we have a design everyone loves. These are then developed further into construction drawings as necessary for building and permitting.
