Medical Marijuana Builder



We are a full service grow facility construction firm.

Led by a team of grow-specialists, and having constructed over 3,500,000 square feet of warehouse, manufacturing and processing facilities, the Cannabis Design Build team has the knowledge and experience to serve as your commercial cultivation, processing and dispensary facility design/build partner.   





Cannabis Design Build is an extension of Paul Risk Construction (PRC), located in Quarryville, Pa. With the legalization of medical marijuana in Pennsylvania in April 2016, PRC saw an opportunity to utilize their extensive design/build experience within this new and growing industry. With the backing of this fourth-generation, family-owned business, and the addition of a leadership team with in-depth industry-experience, Cannabis Design Build now serves as the Mid Atlantic's premiere medical marijuana grow facility contractor.




We are design/build specialists.  For over six decades, we've specialized in design/build, and have served as a full-service partner to hundreds of satisfied clients. With a legacy built on trust, we strive to use our knowledge and talents to build custom solutions for our clients.

MMJ Site Analysis

The first step in our process is to execute a site assessment, feasibility study and, if necessary, an energy audit. Whether it's new construction or renovation to an existing structure, this assessment will provide you with key insights that serve as a decision-making roadmap for future phases of the project.


A building is only as strong as its foundation. The preconstruction phase serves as this foundation for the rest of the construction project, and is vital to ensuring ROI on your commercial grow room investment. During this phase, we explore design, function, materials and schedule as well as refinement to concept budgets, cost estimates and construction schedules. With a focus on value engineering early in the process, our aim is to build a high-yield grow facility within your budget.

Commercial Grow Room Design

With over 60 years of design/build experience, this is where we thrive. As your full-service grow contractor, we assign a custom team to partner with you from the first sketch of the blueprints to the final walk through after construction. This team will work with you to ensure that all aspects of your project meet state standards and will incorporate the essentials of your business into your grow facility design: from cultivation and processing to sales and retail. Services provided during this phase include civil engineering, architectural services and security systems, as well as grow room specific needs such as climate control, irrigation, lighting, bench and extraction systems.


Construction Management

As both your construction manager and general contractor, Cannabis Design Build serves as your full-service grow contractor, providing the necessary project management, onsite supervision and quality control to deliver a high-yield, cost-effective grow facility.


As a general contractor, the Cannabis Design Build team serves as your project lead. Through a competitive bid process and our extensive network of partners, we will build a custom team of specialists needed for your commercial grow room construction project: from specialty contractors to equipment suppliers.


There are a lot of moving parts to setting up a large scale grow room, but we aim to make it as streamlined for you as possible by providing a dedicated project manager and superintendent to oversee your entire project. Through this approach, we stay focused on project schedule, quality and cost, while keeping you informed during each phase of the project.

Product Selection & Growth Management
