Mura turns a folder of inspiration photos into a document your contractor can actually use — covering materials, finishes, budget, and scope. Built for the 1.8 million home renovations that happen every year in Spain, where most people show up to the first meeting with a phone full of photos and no way to explain what they actually want.
Try it — upload a photo, describe your space, and get the brief.
What it is
A tool for anyone planning a home renovation to communicate their vision to a contractor — without design training. You upload a photo of your current space, describe what you want in natural language, and the AI generates a photorealistic visualisation of the result alongside a professional downloadable brief. The brief covers materials, finishes, and budget — structured the way contractors think, not the way homeowners describe. Built for Spain's 1.8 million annual renovations, where most people show up to contractor meetings with a phone full of photos and no way to explain what they actually want.
How we built it
Built in six weeks, with a team of three, as part of a product direction course. We started with user interviews and found the same gap everywhere: the visual references existed, but no way to translate them into something actionable for a contractor. The core challenge was chaining two AI models without losing coherence across edits — Claude Sonnet to understand intent and generate precise editing prompts, and Nano Banana to apply those edits iteratively to the same photo, preserving room geometry while changing only what was asked. Each refinement builds on the previous result, not the original. To avoid exposing API keys on a static frontend, we routed everything through a Cloudflare Worker — which also let us move fast without a dedicated backend.
