Our Single-Source Process

Colao & Peter is proud of our unique background which has helped us grow into one of the most reputable landscape design/build firms in the Washington DC metropolitan area. The company emerged from a joint venture between Joe Colao, (who owned and operated Milestone By Design, a stone importing and masonry company) and J.R. Peter (Registered Landscape Architect) who designed and managed some of the areas highest-end landscape architecture projects.  The union of the two principles allowed for the creation of a true design/build firm which keeps all the design and installation in-house.  This allows us to control all aspects of the project from design through final construction.

Design Consultation

We start our process with a simple design consultation. During this meeting, we understand the client's vision while also studying their current landscape conditions, allowing us to formulate a few possible directions under the scope they have outlined. It is important that we gather as much information as possible from the client in order to design to the client's wants and needs.

Everyone is on the Same Team

We believe that projects are a collaborative effort.  Our team members consist of the architects, installation contractors and our clients all working together to achieve the goal of exceeding every expectation.

Total Accountability

We are a one-stop-shop from initial design to final installation making us accountable during every stage of the project.  This process ensures that design, cost and completion deadlines are managed in harmony and stay within the parameters of the project, without compromising quality.


As a design/build firm, we are experts in both trades. There is a great advantage to working with a firm that understands how to design a project that looks great but that can also be built efficiently.


Often, designs are pushed onto clients by designers rather than listening and interpreting what they want or need. We prefer to work closely with our clients, making sure that the final product matches their vision.

Cost Savings

Our process ensures efficiency in drawings and time savings during production. With our in-house design and construction professionals, all players involved in the project have an open line of communication, removing the inefficiencies and achieving complete client satisfaction.
