Nordquartier Lemwerder: buyers place their own house on the plot
3D site plan
All 18 plots to scale from the survey data, with size, price, garden direction and the real position of the sun over Lemwerder.
House studio
Place six house types on any plot they fit, choose facade, roof and windows, and save the view as an image.
See the payment
From plot, house, savings and KfW loan the site works out the monthly payment and sends it to the advisor with the inquiry.
Starting point
The new development on Streubelinger Dorfweg in Lemwerder-Altenesch has 18 fully serviced building plots. A local builder builds the houses; a financial advisor sells the plots and advises on financing.
Buyers face three questions: which plot suits us, which house fits on it, and what will it cost us each month? Zoning plans, cadastral maps and a PDF price list barely answer them. The website had to settle all three before the first conversation.
Approach
- 01
Plans become a 3D model
I read plots, streets, building envelopes and sewers from the vector data of the survey, the zoning plan and the drainage plan. Every house stands where the zoning plan allows it: inside the building envelope and clear of every boundary.
- 02
Life first, then the plot
The homepage shows who moves in here: families, couples and two generations under one roof. Each group finds its house type and its path to an inquiry, and the copy is written from the buyer's point of view.
- 03
Fast, on the phone too
The pages run on Astro on Cloudflare. The text appears at once, the 3D view loads after it and uses lighter graphics on weaker phones. Inquiries arrive through Cloudflare Email Routing, and Cloudflare Zaraz only measures after consent.
Result
nordquartier-lemwerder.de has been online since November 2026. Buyers choose plot and house themselves, see which way their garden faces, and send their numbers with plot, house and payment straight to the advisor.
The client gave their feedback right on the website, with Margin, my own tool for website feedback. Both rounds of comments were done the same evening.
