About PatioPlanner
Hey, I am Christoph. I am a Cloud Systems Engineer. When I am not deploying AWS infrastructure or doing heavy DIY work around the house, I build small tools. I like tools that solve exactly one problem and just work.
Why This Exists
I paved a patio myself. 40 square meters, concrete pavers in a running bond pattern. The most annoying part was not the laying. It was the math beforehand. How many stones do I need? How much waste should I account for? What does the pattern look like at the edges?
So I built a planner. Draw the area, pick the stone format, choose the laying pattern, done. Quantities appear immediately. No signup. No payment. No upload.
What It Does
- Area planning: Draw areas with exact dimensions, from simple rectangles to L-shapes, several on one drawing.
- Pattern selection: Compare laying patterns directly on your area.
- Quantity calculation: Stone counts per format with a waste allowance, plus base, bedding and curbstones.
- Export: Print or save as PDF, PNG or share link.
Technology
Built with Astro, React, Konva and Tailwind CSS. All calculations run locally in the browser. No server processing. Projects are saved in Local Storage.
Support This Project
If this planner saves you time and nerves on your next project, you can support it in two ways.
Option 1: Cover hosting costs. You buy me a virtual coffee. That helps with the monthly server bills and keeps development going.
Option 2: Do something more meaningful. I honestly prefer this option. As a father, projects that help children are very close to my heart. If you like this tool, please consider donating a small amount to Kinderhaus Weimar.
