Comparing house plans side by side

Guide

Updated October 13, 2026

How do I compare house plans side by side?

Tick Compare on up to 4 plans, on their cards or plan pages, and open the bar at the bottom of the screen. The plans line up page by page in one book: fronts, footprints, floor plans, rooms and specs, cost to build and price. Only the footprints page is drawn to one shared scale; the fronts are illustrative renderings and the floor plans are not at the same scale.

Building the book

The Compare boxes remember your picks in this browser, without an account, up to 4 at once. The book is one link with the plans in it, so you can send it to whoever you are building with.

Saving a plan with the heart is different: saved plans live in an account, so saving asks you to sign up or sign in.

What is to scale, and what is not

Footprints to scale: every footprint is drawn at one shared scale from the plan's width and depth in feet, front at the bottom, with a scale bar, then laid over each other on a 10 foot grid with the front left corners together. Solid lines are heated space; dashed are garage and covered porches. A plan with no drawn outline shows its full width by depth box.

Fronts: illustrative renderings in the same frame. They are not photographs of built homes and not to scale.

Floor plans: each at its own size, not to the same scale. Use the footprints page to compare sizes.

Specs, cost and price

The rooms and specs page lines up heated area, beds, baths, stories, garage, width, depth and the rest, and marks the largest or smallest where that is a plain measure, not a ranking.

The cost page takes your lot ZIP and shows that county's new single-family home permits from the US Census Bureau's Building Permits Survey, which reports new privately owned residential construction down to the county. [1] The site does not publish a cost per square foot, so there is no per plan price rather than an invented one; a local builder can price each plan for your lot.

The last page has license prices, foundation options, the designer and what each drawing set leaves out.
