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. Our design team combines technical training, creative skill, and deep local knowledge to bring your vision to life.
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. Our team also understands the complexities of local zoning, building codes, and site-specific design on Cape Cod, which allows us to anticipate challenges early in the planning process.
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
- Exterior architecture and façade design
- 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
We begin with an on-site visit to assess your property’s setting, elevation, and surroundings. For home additions and renovations, we take detailed measurements of your existing home and review any available plans.
During this consultation, we discuss your goals for layout, style, and functionality—including outdoor spaces and must-have features. From there, we create a design outline that becomes the foundation of your custom plan.
If needed, we coordinate with a trusted local civil engineer to perform a complete site survey, documenting topography, boundaries, and zoning data. This ensures your design aligns with Cape Cod’s environmental and permitting requirements.
Using the design outline and survey data, we develop as-built drawings and create proposed floor plans and elevations. Clients often review early versions through detailed 3D renderings or architectural renderings, helping visualize how the design will look and flow.
We refine each iteration until your vision is fully realized, then finalize construction drawings for permitting and build.
