LotLine

Lotline — Floor Plan Maker

Plan your perfect lot before you ever open the game.

Lotline is a free, browser-based floor plan tool built with Simmers in mind. Whether you're mapping out a cosy starter home, a sprawling legacy mansion, or a carefully zoned community lot, Lotline lets you sketch it out tile by tile before you commit a single Simoleon.

Features:

• Grid-based drawing scaled to Sims lot proportions (1 tile = 3 ft)
• Horizontal, vertical, and diagonal walls — including ╱ ╲ and ╳ (the ╳  can be used in place of specific furniture items, like fireplaces, sofas, counters, etc.)
• Stair placement with directional control
• Adjustable wall thickness and colour
• Resizable grid up to 100×100 tiles
• Upload a reference image (blueprint, inspo screenshot) as a background layer
• Pinch-to-zoom and touch pan support for touchscreen laptops and tablets
• Export your plan as a PNG to save or share
• Share your floor plan via URL — anyone with the link can open and keep editing
• Works in any browser on Windows, Mac, Linux, Android, and iOS — no install needed, no account required

How to use: Download the HTML file, open it in your browser, and start drawing. That's it. You can share the file directly with friends or use the built-in Share button to generate a link to your specific plan.
