A sense of place

Designing the life between indoors and out.

Every project begins with the character of the site: its light, movement, materials, existing trees, views, and the way people want to live there. Petra’s work brings those elements together into outdoor rooms that feel natural, welcoming, and distinctly personal.

Process

From first conversation to finished garden.

  1. 01

    Discover

    We begin with a conversation about your property, lifestyle, goals, budget, and timing.

  2. 02

    Compose

    We study the site and develop an initial design direction shaped by light, movement, materials, and planting.

  3. 03

    Develop

    We refine the concept into a clear design plan with the details needed to move forward.

  4. 04

    Realize

    We support implementation with thoughtful coordination so the finished space reflects the design intent.

The first step is a free 15-minute discovery call.

The studio

A lifelong relationship with gardens, translated into outdoor rooms.

Petra’s love of gardening began in childhood, working alongside her mother and learning to notice the quiet changes of seasons, color, texture, and light. That sensitivity continues to shape the way she approaches every project today.

“My passion lies in bridging the gap between outdoor and indoor living, creating spaces that blur the boundaries between indoors and out.”

“We couldn't be happier with the transformation of Surf Lodge's outdoor spaces. Petra listened to our vision and brought it to life with an extraordinary blend of creativity and functionality, integrating unique materials that make the courtyard feel welcoming and distinctly modern. Her attention to detail turned the space into a relaxing oasis, and guests tell us so constantly.”
