About Cocoon Remodeling

Accessory Dwelling Units by Cocoon Remodeling

An accessory dwelling unit (ADU) can add meaningful value to a property — whether the goal is to house family members or generate rental income. Cocoon Remodeling, serving West Chester and the broader Philadelphia suburbs, works with homeowners to design and build ADUs that fit their specific property and lifestyle needs.

From transforming an underutilized basement into a private apartment with aging-in-place features, to constructing a detached backyard cottage suited for renters, Cocoon Remodeling approaches each project with a focus on practical design and local compliance. As an experienced ADU contractor in the region, they stay current on zoning ordinances and building codes across the various boroughs they serve.

Why Homeowners Consider Adding an ADU

An accessory dwelling unit is a self-contained living space added to an existing property. It can be attached — such as a garage conversion or basement unit — or detached, like a standalone backyard cottage or granny flat. Common reasons homeowners pursue ADU projects include:

  1. Multigenerational living: An ADU provides a separate but nearby space for parents, adult children, or other relatives, balancing closeness with privacy.
  2. Rental income: A well-designed ADU can be rented to local university students, young couples, or other tenants as a source of supplemental income.
  3. Future planning: Homeowners who want to age in place can build an ADU now and adapt it for their own use later, designing it around the needs of older adults from the start.

Most ADUs are designed for independent living and typically include a bedroom, living area, bathroom, and kitchen. Additional features — such as a breakfast nook or a more spa-like bathroom — can be incorporated based on the homeowner's preferences and budget.

Popular ADU configurations that Cocoon Remodeling works with include:

  1. Interior ADUs connected to the main home
  2. Garage conversion units
  3. Basement apartments
  4. Attic conversions
  5. Detached standalone structures

Cocoon Remodeling's ADU Process

Adding an ADU involves more than construction work alone. Local zoning codes, permitting requirements, and design decisions all need to be managed carefully. Cocoon Remodeling handles the full scope of the project through a structured three-stage remodeling process designed to keep things organized and reduce stress for the homeowner.

The first two stages — typically spanning around four months — focus on developing the design, refining the layout, and working through the regulatory and permitting details. The third stage covers the actual build, which generally takes an additional two to four months depending on the complexity of the project. In total, most ADU projects are completed within six to eight months.

As a local accessory dwelling unit builder, Cocoon Remodeling is familiar with the varying regulations across Philadelphia suburban communities. They assist homeowners in navigating the permitting process and ensuring the final design meets all applicable local requirements.

For homeowners unsure whether their property can accommodate an ADU, Cocoon Remodeling's team can assess the site and advise on the most suitable approach — whether that's a detached ADU, a garage conversion, or an interior unit. Detailed cost estimates are provided during an initial consultation, as pricing depends on factors such as size, design complexity, and materials used.

Cocoon Remodeling serves homeowners throughout West Chester and the surrounding Philadelphia suburbs looking for a reliable ADU builder to guide them through the process from initial concept to completed construction.

"First-Class Experience from Start to Finish We recently completed a 12-week home remodeling project with Cocoon, and we couldnt be more pleased with the entire experience. From the initial design phase with Max and Evangeline to the construction and finishing process led by Keith, every step was handled with professionalism, care, and attention to detail. Max and Evangeline brought our vision to life with thoughtful design ideas and a collaborative approach that made us feel heard and supported. Once construction began, Keith ensured everything ran smoothly and on schedule. His communication and project management were top-notch, and the craftsmanship delivered by the team was exceptional. The entire process was seamless, and the final result exceeded our expectations. Cocoon truly delivered first-class service with a first-class outcome. We highly recommend them to anyone considering a home remodel."

"COCOON helped us with the design and renovation of our main bedroom and bathroom, laundry room and two closets. Im not sure I can imagine a better process. From start to finish, the folks at COCOON were truly great. During the planning stage, we were offered some great floor plan options, including some really unique and unexpected options that showed they were thinking hard about how we could best use the space. They also have architectural and interior design folks in house, which streamlined what I thought would otherwise be a complicated process of moving walls, designing the new space, etc. Chris M., our project manager, was really excellent. He did a great job with communicating the status of the work and helping us with some nuts-and-bolts decision making. They use the app BuilderTrend, which is a great tool to follow along with the construction process and to help with design choices. We are really happy with how everything turned out. Its a great local company, and we are so glad we chose to partner with them."

"Carolyn and I couldnt be happier with the communication, professionalism and care for exactly what we desired in our new kitchen. We didnt get a remodel but a complete replacement including walls, ceiling and window. The design and workmanship was first class along with our Project Manager, Greg and all of the disciplines Carpentry, Electrical, Flooring, Paint, etc. that made our project a reality. Thanks to the Cocoon team!"

"At first meeting I knew Cocoon would work with my vision of our forever home. The design team came to my home for each meeting, bringing numerous samples of tile, cabinets, paints and hardware. After weeks of decisions the project was ready to begin. Our plan was to open up the entire first floor including living, dining, kitchen and family room. Walls were removed, old ceramic floor tiles were replaced with beautiful white oak flooring matching the existing living room. My kitchen doubled in size and is now perfect for entertaining. The demolition and construction seemed flawless. The numerous contractors, each with superior skills, worked together to completion. Our project manager was on site each day and communicated with photos and a description of the days progress. Did I mention that my husband and I left for Florida the day the work started and returned months later when nearly completed! I absolutely recommend Cocoon. Our reimagined first floor is perfectthe result of Cocoons expertise, planning and quality craftsmanship. Could not be more pleased and would not change a thing!"
