3D House Planner
3D House Planner is a free, browser-based design suite for houses and apartments. It combines a 3D floor planner, a material editor, a 2D planner and AI rendering that turns sketches or photos into photorealistic interiors and gardens.
What is 3D House Planner?
3D House Planner is a browser-based architectural design application for drawing houses and apartments, with nothing to install and no account to create. Opening the site is enough to start: walls, floors, roofs and openings are built in a few clicks, and a single project can stack up to 50 storeys. A catalogue of several thousand objects, organised room by room, handles furnishing and decoration, while a texture library and terrain modelling tools finish the scene.
Artificial intelligence appears in two distinct places. Inside the 3D editor, an imported floor plan image can be turned into a 3D plan with a single click. Separately, an AI Design Rendering workspace converts a sketch or a photograph into a photorealistic image, through five modes covering interior redesign, interior and exterior sketch-to-render, gardens and a renovation video. Each render is steered by a text prompt, an AI Intervention slider running from Very Low to Extreme, a choice between a precise mode that follows the sketch edges and a creative one, some twenty-five architectural styles, thirty-five garden styles and six aspect ratios.
Three companion applications sit under the same brand: a standalone material editor for PBR textures applicable to any imported model, a drag-and-drop 2D floor planner that exports to PDF, and a set of five home finance calculators covering borrowing capacity, mortgage payments, prepayment, energy savings and renovation costs. Models move in and out in GLB, GLTF, OBJ and Babylon formats.
The whole suite is free, without watermark, subscription or sign-up, funded by voluntary PayPal donations and by Google advertising displayed on the site. That choice shapes how the tool behaves: there is no cloud storage, the operator states that it collects no design data, and saving a project means exporting a file to your own device. Nothing is kept online, so nothing can be resumed on another machine or handed to a colleague. The 3D catalogue itself is assembled from Creative Commons sources, each credited on the homepage.
What it does
- Build walls, floors, roofs and openings in a few clicks, across up to 50 storeys
- Convert an imported floor plan image into a 3D plan with a single click, using the AI tool
- Generate a photorealistic render of an interior, a facade or a garden from a sketch or a photo
- Furnish and decorate from a catalogue of thousands of ready-made objects and textures
- Apply PBR or standard materials to any imported 3D model, and model or paint terrain
- Import and export GLB, GLTF, OBJ and Babylon models, then capture snapshots or record video
- Estimate borrowing capacity, mortgage payments or renovation costs with the built-in calculators
When to use 3D House Planner / When not to
A quick filter to help you decide if 3D House Planner is the right fit.
When to use 3D House Planner
- Homeowners planning a build or a renovation without a software budget
- Interior designers who need a fast concept visual before a client meeting
- Real estate agents illustrating a property's layout or its renovation potential
- Architecture and design students, since nothing has to be installed or paid for
- 3D hobbyists looking for a free GLB/OBJ viewer with a PBR material editor
When not to use 3D House Planner
- Practices working in BIM, as no IFC or BIM exchange format is supported
- Teams needing real-time collaboration, since there are no accounts and no shared projects
- Anyone expecting to resume work on another device, as saving means exporting a file locally
- Buyers requiring contractual guarantees: no DPA, no SLA and no published legal entity
- Developers looking for an API, which the tool does not provide in any form
How to use 3D House Planner
A typical end-to-end flow, from setup to results.
- Open 3dhouseplanner.com in a WebGL-capable browser — no registration is required
- Click Start Designing to launch the 3D editor
- Either begin from a blank scene, or import a floor plan image and let the AI tool build the 3D plan
- Draw walls, floors, roofs and openings, stacking up to 50 storeys
- Furnish from the Objects tab of the catalogue and finish surfaces from the Textures tab
- Import your own GLB, GLTF, OBJ or Babylon models if the catalogue is not enough
- Refine appearance in the Material Editor: PBR materials, metalness, roughness and relief mapping
- Model and paint the surrounding terrain, then take snapshots or record a video of the scene
- Export the 3D model to your device — this is the only way to keep the project
- For a photorealistic image, open AI Design Rendering, upload a sketch or photo, set the mode, prompt and style, then download the result
Pros & Cons
Pros
- Genuinely free, with no watermark and explicit permission to use exports commercially

Data, GDPR & hosting
A consolidated view of how 3D House Planner handles your data.
GDPR overview
The privacy policy carries a dedicated General Data Protection Regulation (GDPR) section. The operator declares itself a Data Controller, lists four lawful bases — performance of a contract, consent, legitimate interest and legal obligation — and enumerates the rights of EEA residents: access, update, erasure, rectification, objection, restriction, portability and withdrawal of consent. Implementation stops there. The policy is explicitly generated by GDPRPrivacyPolicy.net, and rights must be exercised by contacting an operator that publishes no company name, no postal address, no Data Protection Officer and no Article 27 representative — only one generic email address. There is no data processing agreement, no subprocessor list and no stated retention period, while Google advertising cookies, including DoubleClick DART, are in use. The framework is declared; the accountability that would make it verifiable is not.
Who owns the data?
Under the Terms and Conditions you keep ownership of what you create: the document reserves the site's intellectual property to the operator and its licensors other than the content you own. That ownership comes with a significant caveat. By displaying content on the site you grant 3D House Planner a non-exclusive, worldwide, irrevocable and sub-licensable licence to use, reproduce, adapt, publish, translate and distribute it in any and all media, and the operator may remove content at any time without notice. Designs themselves are far less exposed: the homepage states that there is no cloud storage and that no design data is collected, so scenes never reach the operator's servers. No legal entity is ever named as the holder of that licence.
Reuse rights
The site grants broad reuse rights over what you make: imported and exported 3D models may be used for personal or commercial purposes, a permission repeated on the homepage, the material editor and the 2D planner, with no watermark and no licence fee. Models can be exported in GLB, 2D plans saved as PDF, and the workspace can produce snapshots and video. The restrictions sit elsewhere: the Terms forbid republishing, selling, sublicensing or otherwise commercialising website material as such — the object catalogue and textures rather than your own drawings — and prohibit data mining or scraping of the site. One caveat deserves attention: the catalogue is assembled from several Creative Commons sources, and the ArchiBit Generation models are licensed CC BY-NC-SA 2.5 IT, which excludes commercial use and therefore contradicts the blanket commercial permission announced elsewhere on the site.
Data retention & training
Hosting summary
The site publishes no hosting country and no hosting region. Technically, the domain sits behind Cloudflare: the resolved address, 172.67.164.183, belongs to AS13335 and geolocates to San Francisco, but that is an anycast edge node rather than a storage location and must not be read as the country where data lives. The registrar, PDR Ltd. d/b/a PublicDomainRegistry.com, is Indian and has no bearing on hosting either. The operator's own position is that designs are not hosted at all: the homepage states there is no cloud storage, that work remains private and that no design data is collected, saving being done by exporting a file to the user's device. What does reach a server is narrower but real: log files recording IP address, browser, internet provider, timestamps and pages visited; cookies, including Google's advertising cookies; and the images uploaded to the AI rendering workspace, whose hosting is nowhere documented. Jurisdiction is the one explicit legal anchor: the Terms and Conditions submit to the laws and courts of Brazil. No standard contractual clauses, transfer mechanism, data processing agreement or subprocessor list is mentioned.
Things to keep in mind
Risks and trade-offs to weigh before adopting 3D House Planner.
- Losing work is easy: with no cloud saving, a closed tab or a crash wipes an unexported session
- The publisher cannot be identified — no company, no address, one generic email — so there is no practical recourse in a dispute
- Brazilian law and Brazilian courts are imposed by the terms, with no negotiation and no stated entity to sue
- The licence granted over displayed content is very broad, and sits awkwardly beside the commercial promise that nothing is collected
- Images uploaded to the AI renderer have no documented provider, retention rule or training policy: confidential plans do not belong there
- Google advertising and DART cookies track visitors on a site that presents itself as privacy-first
- Photorealistic AI renders can mislead if shown as a buildable project: the tool performs no structural or regulatory check and replaces neither architect nor engineer
Setup & Integrations
Technical difficulty
Setup is essentially non-existent: one URL, one browser, no account, no configuration and no API key. The only real prerequisite is a browser supporting WebGL — Chrome, Firefox, Edge or Safari — and a machine able to display a 3D scene comfortably. The single habit to acquire is saving by export: there is no autosave and no cloud project, so work must be deliberately written to a file. Handling 3D objects and PBR materials rewards some prior familiarity, but nothing in the interface assumes it.

Should you pick 3D House Planner?
3D House Planner offers an unusual value proposition: a complete browser-based design suite — 3D planner, material editor, 2D planner, AI rendering and finance calculators — for nothing at all, with no watermark, no subscription and no sign-up. For a homeowner sketching a renovation, a student learning spatial design or a designer producing a quick concept image, the barrier to entry is effectively zero.
That absence of an account is both the tool's strength and its ceiling. It delivers real privacy, since the operator stores nothing and states that it collects no design data, and it makes the tool usable within seconds. It also means there is no way to resume a project on another device, no collaboration, and a genuine risk of losing work: exporting a file is the only save mechanism.
The artificial intelligence is a useful accelerator rather than the heart of the product. Turning a plan image into a 3D model and rendering a sketch into a photorealistic view both save real time, but the underlying tool remains a manual 3D editor, and the rendering feature comes with no published documentation on where uploaded images go or how long they are kept.
The most serious reservation is legal rather than technical. No company name, postal address or registration number appears anywhere on the site; the single contact channel is one generic email address, and the terms place any dispute under Brazilian law. There is no data processing agreement, no subprocessor list and no stated retention period. For personal projects, teaching or early-stage exploration, that opacity is a reasonable trade for a capable free tool. For professional work under contract, or for anything involving confidential plans, it is not.
