C-Home Design LLC, founded by Mark P. Costello, is a premier home design and construction firm with over 45 years of experience in the industry. Mark received his Bachelor of Architecture from the University of Oregon in 1980 and has since developed a strong capability to blend innovative design with high-quality construction. The company was previously known as Costello Design LLC and MP Costello Design and Construction LLC, but has since consolidated its services under the C-Home Design brand.
The mission at C-Home Design is to help clients reflect their lifestyles in the spaces they inhabit, while maximizing a property's natural features, including views, sunlight, and landscape. This personalized approach to design ensures that each project not only meets the aesthetic desires of the client but also enhances the functionality and livability of their environment. By maintaining a commitment to staying current with design trends, innovative products, and construction costs, C-Home Design ensures that clients are well-informed to make the best choices for their projects.
C-Home Design LLC offers a wide range of services, including home design, multifamily design, remodels and additions, and the design and application of Additional Dwelling Units (ADUs) to municipalities. Mark's extensive experience extends to project management and problem-solving, allowing clients to navigate their construction journeys smoothly, whether they choose to work with C-Home or their own contractors.
Mark is a community-active individual, having lived in Bellingham his whole life, and he embraces local involvement as both a past president of the Bellingham Central Lions and a dedicated member of his community. His diverse background, including commercial fishing and operating a local café, adds a unique depth to his approach, ensuring that every project is not just a construction job, but a collaborative venture infused with dedication and passion.
