Jenn Lassa and Marcin Matlakowski met in 2008 while working as landscape professionals in Chicago. They quickly realized their shared enthusiasm for beautiful design, the outdoors, and living life to the fullest would make them perfect partners in business and in life! They decided to take their talents to the next level and launch their own business where they could devote their time and energy to designing and building outdoor spaces that inspire others and in 2009 Rooftopia was born.

A few years later in the fall of 2013, Jenn and Marcin were married in a picture-perfect farm wedding surrounded by family and friends. They have enjoyed every minute of doing the work they are passionate about and look forward to a bright future together bringing beautiful outdoor spaces to life in Chicago.

We work around your busy schedule to set up an appointment at your space to gather measurements, photos and ideas. After we discuss the wide range of possibilities, fully understand your garden aspirations, existing architectural elements and the outdoor access points, we can begin to bring the garden of your dreams to life.

Estimates & Concepts

After our consultation, we will begin estimating and conceptualizing custom garden elements for each outdoor location. Detailed estimates will outline our design fee, based on the size and scope of your project. Our estimates and concept drawings are tailored to meet each of our clients individual outdoor living goals.

Design Process

Our design process is unique, for each client and each outdoor space. We ensure that you receive nothing less than attentive and reliable service through every aspect of the garden’s development from concept illustrations through final revisions. Our specialized design process guarantees that all garden elements have been organized and prepared, so there are no surprises during the installation of the project and that it is completed within the specified time frame. To ensure exceptional results we follow sustainable, harmonious design principles to inspire each rooftop garden or landscape.


Once a project is under contract our obligations and our clients are clearly defined. We want to complete each garden efficiently, and within your budget. We take great pride in our craftsmanship, building each project with the highest quality standards for longevity, beauty and sustainability. All of our outdoor living spaces and custom garden elements are designed and built to meet city code regulations and safety standards.


After we complete your installation, we will work with you to establish the best possible care and maintenance for your landscape or outdoor living space. We have many maintenance options depending on the plants and systems we have installed. It is our goal to install primarily low-maintenance plants and offer seasonal gardening services to keep your outdoor oasis picture perfect.
