Space Designer 3D: cost, fit and limits

What to know first
Space Designer 3D sells two subscription plans with a 5-day trial that needs a card and charges nothing at signup: Premium at $25 per month and Ultimate at $45 per month. Both run on a monthly credit pool, 200 on Premium and 370 on Ultimate, which pays for renders, AI images and plan detection. Ultimate adds unlimited projects, 10 floors, advanced AI tools and CAD exports.

Who Space Designer 3D is best for
Designers needing quick visuals
The homepage says a 2D floor plan becomes an HD or 8K photorealistic image in one click, which helps when a client wants to see a room the same day.
Homeowners with a single project
Premium covers 25 projects and 5 floors in the browser with no download, so one house can be planned and rendered during a month of subscription.
Studios that deliver CAD files
CAD exports are listed on Ultimate, where the 370-credit pool also includes advanced AI tools and unlimited projects for several clients.

What Space Designer 3D does
- AI rendering from a 2D plan
- The homepage says a floor plan becomes an HD or 8K photorealistic image in one click. Each render draws credits from the same monthly pool as other AI outputs.
- Built-in 2D editor and 3D walkthrough
- The editor, a 3D walkthrough and smart measurements are all inside the browser, so a plan can be drawn, toured and measured without installing software.
- Plan detection
- Plan detection is a credit-consuming function, so uploading a drawing to be recognized costs part of the 200 or 370 monthly credits rather than being free.
- Furniture and structure tools
- Premium has a catalog of 2,500+ furniture items, plus roof, stairs and annotations and PDF export, which is smaller than catalogs of 10,000 or 100,000 items elsewhere in this list.
- Free export named on the homepage
- The homepage mentions exporting HD or 8K renders with a free plan. The pricing page opened lists a trial, not a permanent free tier, so check what is actually included.
How Space Designer 3D handles your data
The pricing page and homepage of Space Designer 3D were opened for this entry; the privacy page was not. They name Asynth SAS as the maker but give no headquarters, no retention period, no hosting region and no certification, and they do not say whether uploaded plans or generated images train AI models. Since AI images and plan detection are sold as credit items, floor plans are processed by AI features. Request the privacy policy and ask whether a third-party model provider handles your images before you upload client drawings.
Where Space Designer 3D falls short in practice
- One credit pool for everything. Renders, AI images and plan detection share 200 credits on Premium and 370 on Ultimate. A project with many views or revisions can exhaust the pool before month end.
- Project and floor caps. Premium stops at 25 projects and 5 floors and Ultimate at 10 floors, so a multi-storey building or a studio with many clients needs the higher plan.
- Card needed for the trial. The 5-day trial requires a card and nothing is charged at signup. A buyer who forgets to cancel will be billed monthly, which a no-card free tier would avoid.

Space Designer 3D: common questions
How much does Space Designer 3D cost?
As of November 2026 the pricing page shows Premium at $25 per month and Ultimate at $45 per month, each with 5 days free and $0 at signup. A yearly option is described as saving 17 percent. Credits per month are 200 on Premium and 370 on Ultimate.
Is there a free plan on Space Designer 3D?
The pricing page opened shows a 5-day trial that requires a card, not a standing free tier. The homepage mentions exporting HD or 8K renders with a free plan, so the free offer may be described differently there. Confirm in the signup flow before relying on it.
What do Space Designer 3D credits pay for?
Credits cover renders, AI images and plan detection on Premium, with CAD exports added on Ultimate. Premium gives 200 per month and Ultimate 370. The pages opened did not list the credit cost of each action, so test a project to see how fast the pool drains.
Does Space Designer 3D need a download?
No. The homepage says the tool is browser-based, with a 2D editor, a 3D walkthrough and smart measurements built in. Output includes HD or 8K renders, and Premium adds PDF export. CAD export requires the Ultimate plan. The vendor lists smart measurements in the editor.
How many projects can I keep in Space Designer 3D?
Premium allows 25 projects and 5 floors, while Ultimate gives unlimited projects and 10 floors. Both plans draw on monthly credits for renders. If you only need one house planned once, a single month of Premium may be enough, since the plans are billed monthly.
