The published estimates
Three market research firms publish widely quoted figures for the AI in interior design market. Their full reports are paid; the numbers below are from their public summaries.
| Publisher | Base estimate | Forecast | Annual growth (CAGR) |
|---|---|---|---|
| Research and Markets (2026 report) | $1.39 billion (2025) | $4.55 billion (2030) | 26.8% |
| Grand View Research | $3.28 billion (2025) | $15.0 billion (2033) | 20.9% (2026 to 2033) |
| Market.us | $829 million (2023) | $7.30 billion (2033) | 24.3% (2024 to 2033) |
All three agree on direction and region: fast growth, with North America the largest market. Grand View Research puts North America's share at 38.6 percent in 2025 and Market.us at 39 percent in 2023. Beyond that, the figures are hard to compare, for reasons that matter to anyone quoting them.
Why the numbers disagree
- Different definitions. Research and Markets counts "solutions and services" for space planning, material selection, VR and AR visualisation, and personalised design, sold to design firms, architects, real estate developers, and furniture manufacturers. Market.us describes design generation, visualisation, and material selection across residential, commercial, and hospitality uses, with software ("solutions") at 65 percent of its 2023 figure. Whether AR shopping tools, real estate staging, or general design software with an AI feature count as "AI interior design" changes the total a lot.
- Mostly private companies. Most AI design tools are private and do not publish revenue, so market sizes are built from estimates, surveys, and models rather than reported sales.
- Different base years. Market.us starts from 2023, the others from 2025, and forecasts run to 2030 or 2033. Growth rates over different periods are not directly comparable.
- Company lists are not always current. The Research and Markets summary names Modsy among featured companies, but Modsy shut down its consumer design services in June 2022. A dated company list is a reason to read the rest of the report critically.
None of this makes the reports useless. They show that several independent firms see a market in the low billions growing by a fifth to a quarter every year. It does mean that any single number, quoted without its definition, says less than it appears to.
What adoption surveys show
Surveys of the people using the tools are more concrete. The 2026 US Houzz State of AI in Construction and Design surveyed 601 US construction and design businesses in June and July 2026 and 3,149 renovating homeowners in June 2026. Houzz runs a platform for home professionals, so it has an interest in the subject, but the survey sizes and dates are published.
| Finding (Houzz, 2026) | Figure |
|---|---|
| Firms using AI for business tasks, all types | 41%, up 7 points from a year earlier |
| Design firms using AI for everyday business tasks | 39% |
| AI-using design firms that use it for planning and design | 68%, double the year before |
| Of those, share using it for pre-project visuals | 82% |
| Time saved by design firms using AI | 3.6 hours a week on average |
| Estimated annual productivity gain per design firm | $80,000 on average (Houzz estimate) |
| Design firms satisfied with AI | 84%, up from 70% |
| Construction firms using AI for everyday tasks | 52% |
The picture is of a tool that most design firms have not yet adopted for everyday work, and that the ones who have mostly use for early concept images, marketing, and admin rather than for final designs. That matches what we see in the tools themselves: good at quick visual options, unreliable on measurements.
How homeowners use AI
Among renovating homeowners, Houzz found 22 percent had used AI for their projects, with use falling sharply with age.
Those who used it mostly used it early in a project: 64 percent to gather ideas, 58 percent to visualise concepts, and 50 percent to compare options. And 80 percent still hired a professional for their renovation. For homeowners, AI is currently an idea and visualisation tool that sits in front of the real decisions, not a replacement for them.
How to read a market report headline
- Find the definition. What does "AI interior design" include: software only, services, AR shopping, real estate staging?
- Note the base year and forecast year. A 2023 figure and a 2025 figure are not the same market size.
- Check who published it and why. Press releases for paid reports are written to sell the report; vendor blogs quoting them are written to sell a product.
- Look for a survey behind it. Adoption figures with a stated sample size and date are easier to check than a modelled revenue total.
- Quote the range, not one number. If you need a figure, "estimates for 2025 range from about $1.4 billion to $3.3 billion" is accurate; "$3.3 billion" alone is not.
What it means if you are decorating
A fast-growing market means more tools and lower prices, not necessarily better accuracy. The limits we found when testing AI room tools, such as invented furniture and unreliable dimensions, apply whatever the market is worth. Useful next reads:
