This summer my dad wanted a new fence and deck. The quotes took over a week. Looking at it from the carpenter's side, the hard part isn't the calendar, it's driving out to measure before you can even write a quote.

So I built Karlsson Staket & Altan, a made-up solo carpenter in Kristianstad, Sweden, where the customer does the measuring by drawing.

For the customer:

Search the address and draw the fence or deck on a satellite map – length and area are measured automatically

Shape it in 3D: height, material, railings, stairs

Instant price with the Swedish ROT tax deduction

Pick a build week with live availability and get a booking reference and a calendar file

For the owner

A 12-week season board with drag-and-drop and capacity per week – full weeks disappear for customers

Material lists calculated from the drawing, merged into one order with stock deducted and rounded to full packs, plus a shopping list

One page per project: quote, booking confirmation, work order and draft invoice

Adjust the customer's 3D model and send it back with a comment to their personal project page

How I built it I planned first: chat mode in Lovable, a starter prompt written with Claude Opus 5.5, a hand-drawn design sketch, and a plan I approved before any code. Version 1 stopped at a price, nobody actually got booked, so I kept iterating in small steps. The hardest part was the 3D model. It was bout 10–15 hours in Lovable, using Lovable Cloud and Google Maps, with prices recalculated on the server.

Note: the project photos are AI-genera::ted, and the before/after numbers on the site are estimates, not measured data.

love the 3D part - something I rely heavily on in this commercial app/system I built https://fairdinkummechdecks.com.au
