I built an AI room designer: the hard part was turning taste into controls
Ask someone how they want to redesign their living room and you'll rarely hear something that could go straight into a good AI prompt. Instead, you'll hear things like: "I want it warmer, but not too minimal." Or: "Something like Japandi, but more comfortable." Or even: "I don't know what style I want. I just want this room to look better." For an interior designer, those sentences contain quite…
Creating an AI-powered room designer is easier said than done. The most challenging aspect lies in translating human preferences into a format that an AI model can understand. Initially, developers might assume that generating visually appealing rooms would be the toughest part. However, that misconception proves to be incorrect, as modern image models can already create attractive rooms. The real challenge lies in translating vague human tastes into structured constraints that make the AI-generated result useful.
Traditionally, developers may build AI interfaces that simply require users to describe their dream room and then generate it. For instance, they might ask, "Describe your dream room" and then generate a room based on the user's description. However, this approach hands the hardest part of the product back to the user. The user needs to know how to write a detailed prompt describing the desired room, such as specifying a warm neutral color palette, light oak furniture, low-profile seating, natural linen upholstery, soft indirect lighting, limewashed walls, minimal decoration, subtle Japanese influences, and so on.
Most people do not describe rooms in such a detailed manner; instead, they describe what they want, like making the room warmer, more comfortable, or more modern.
To simplify the user experience, it is essential to build the prompting into the product rather than making users write better prompts. One approach is to provide style presets that allow users to choose a style instead of describing everything in detail. These style presets act as bundles of design constraints, such as materials, color palettes, furniture profiles, lighting, and mood.
Users only need to know one word, like "Japandi," and the product converts that word into a prompt the generation pipeline can use. This approach creates a simple visible control while hiding the underlying complex instructions.
However, style presets can also limit the user's flexibility. Users might want to keep certain elements of their existing room while incorporating new styles. For example, they may want to keep their current sofa, add more hidden storage, or change the lighting without altering the overall style. A completely open prompt box can accommodate these requests, but it can also overwhelm the user with too many options.
Therefore, a more effective approach is to combine structured controls with optional natural language input. This hybrid approach allows users to express their preferences more clearly while still providing the necessary structure for the AI model to generate a useful result.
Another challenge in AI interior design is that even a beautifully generated room may not accurately reflect the user's original space. The model might move windows, remove doors, change room dimensions, or introduce non-existent walls. These discrepancies can make the final result seem unrealistic and detract from its overall appeal. Thus, developers must carefully consider the user's needs and the limitations of the AI models when designing consumer AI products.
