What It Is

Flathaus is a design support and 3D rendering outsourcing service for interior designers. Its core value is not self-serve software, but allowing busy designers to delegate part of—or the entire—design phase to an experienced interior designer, Leanne. The website states that she has a bachelor’s degree in Applied Interior Design and nearly 20 years of residential design experience. The service is positioned as a way for designers to expand capacity without hiring staff, learning new software, or adding fixed personnel costs.

Core Capabilities and Deliverables

Its services cover three main stages: AI-assisted concept design, mood boards, sample ordering, and presentation documents during the concept/schematic phase; space planning, millwork design, material and product sourcing, specifications, requests for quotation, and presentation document production during the design development phase; and photorealistic 3D rendering during the visualization phase. Rendering deliverables are relatively clearly described: 4–6 still images per room, including proofs for review and final edited 4K high-resolution images, with optional 360° panoramas and 720° walk-throughs. In terms of collaboration, the site emphasizes that the service can fit into a designer’s existing workflow and that requirements can be discussed by phone, but it does not specify project management methods, version control, or file handoff standards.

Pricing, Rights, and Compatibility

Flathaus uses a custom quote model. Clients can choose individual services or outsource an entire design phase, but there are no public prices, payment methods, turnaround times, revision limits, or rush-order rules. Licensing and copyright information is also missing, including commercial usage rights for final renderings, source file ownership, asset copyrights, and confidentiality for client project information. As for export and compatibility, the only confirmed deliverables are 4K final images, panoramas, and walk-through options. The site does not state whether CAD, SketchUp, Revit, Enscape, or other formats are supported, or whether source files are provided.

Pros, Cons, and Best Fit

The main advantage is its highly focused positioning: it is clearly aimed at interior designers and can take on a range of back-office tasks from concept through design development to rendering. Customer testimonials also mention rendering quality, attention to detail, and efficient revisions. The downside is that the service appears to rely heavily on individual expertise, while team size and concurrent project capacity are unclear. Pricing, copyright terms, workflow, and compatibility are insufficiently disclosed, so detailed communication is needed before purchasing. It is better suited to small interior design studios, independent designers, and teams that need outsourced capacity during short-term project peaks. It is less suitable for teams that require standardized high-volume delivery or clearly defined enterprise-level contract terms.

Access from China and Alternatives

The website uses reCAPTCHA and involves Google privacy policies, so access from mainland China may be unstable; actual network availability is unknown. Payment methods are also not disclosed, so cross-border payment should be confirmed in advance. Chinese users may consider local rendering studios, freelance rendering artists, or tool-based alternatives such as 酷家乐 and Coohom. If overseas residential aesthetics and English-language project collaboration are needed, Flathaus may still be worth considering.
