1. Define

The dream is defined. Our proprietary and fun discovery process uncovers deep learning about client goals, preferences and requirements. Project Scope, Budget, and Timeline are established. If construction is involved, our design/build team

is assembled, or we work with client’s own teams.

2. Plan

The dream is envisioned. Concepts, Plans and Specifications are defined for every detail.  This phase may include space planning, floor plans, interior elevations, kitchens, baths, cabinetry, architectural features, materials, as well as furnishings. Client input and approval complete each milestone.

3. Create

The dream becomes reality. Rooms take shape, are finished and furnished. From construction and production to installation of the last work of art, our team orchestrates the many talented specialists to bring the plan to life.

Alex collaborates closely with Lisa in leading creative development across the firm’s design projects and media content. Her Masters of Interior Architecture training enables her to digitally visualize and specify our concepts for clients and industry partners alike. Alex’s passion for design and remodeling started at a young age, watching her parents renovate over ten historic Maine properties. When not designing, Alex can usually be found somewhere outdoors, at a concert or hosting a dinner party.

Sienna brings organization and attention to detail and time spent at a Cambridge, MA interior design firm to our creative development and implementation processes. With a French-American education, Sienna split her childhood between the family’s maple sugaring farm in upstate New York and Southern France.Her international background, a degree in art history and exposure to the arts shape an open-minded and unique approach to every design project. Sienna's love of nature, yoga practice and passion for wellness and sustainability help inform her human-centered perspective to design.

Caitlin's years of experience at a well-known architectural firm, along with studies in Hospitality and Graphic Design, poise her to deliver optimal communications at all points along the design continuum. Caitlin’s interests in Photography and Architecture stem from her early childhood years when given a camera and the experience to travel and see the beauty of the world. In her free time, Caitlin enjoys exploring new places, tasting new foods, and working on personal projects.

Nicole brings creativity and discipline in equal measure to her work.  Her design education extends beyond formal training, including experience in commercial interiors and appreciation for cosmopolitan architecture through travel to over 25 countries for competitive ballroom dance. She is passionate about the art of storytelling through design on behalf of clients, and our firm’s focus on honoring architecture and a sense of place. Nicole spends her free time crafting recipes for loved ones, focusing on fitness, and finding inspiration from the intersection of art and nature.
