Case study

CoDesign: a property portal built around how people actually search

A technical preview of a real-estate portal for Córdoba, built to test whether a catalogue, its search and the paths to an agent can be designed as one decision flow instead of a listing grid with a contact button.

CoDesign is an independent technical preview I designed and built to demonstrate this approach end to end. It was not commissioned by an agency, the listings are demonstration data, and no market or sales figures are claimed here — what follows is the reasoning and the build.

The problem this tests

Most agency sites are a grid of listings in reverse-chronological order with a contact form at the bottom. The visitor does the work: scroll, open, compare, give up. The agency learns nothing about what was being looked for.

CoDesign starts from the three questions a buyer or tenant actually has — what operation, where, and how much — and makes them the first thing on the page. The catalogue exists to answer those three quickly, and every path from it leads to a person who can help.

Search as the front door

The hero is the search. Operation, location, type and a price ceiling in the visitor's currency are visible before any listing is, and the shortcuts underneath — houses for sale, rentals, lots, mortgage-eligible — are the searches people repeat most, given a name and one tap.

Listing pages carry what changes a decision: price per square metre alongside the total, surface, rooms, parking, condition, and the agent responsible with a direct contact. Favourites let someone shortlist across visits without an account.

One catalogue, three ways to use it

Buying, renting and short-stay are different markets with different anxieties, but the same properties and the same agents. Rather than three sites, CoDesign runs them as three operations over one catalogue, so the counts by zone and type stay honest and an agent's portfolio is visible in one place.

The valuation flow closes the loop for owners: a request that asks for what an agent needs to prepare — location, type, surface, timing — instead of a name and a phone number.

What the build proves

CoDesign is bilingual on a single codebase, works as a progressive web app, and treats the catalogue as structured data rather than pasted text — which is what makes counts, filters and shortcuts possible at all.

It shows the studio working on an information-heavy product: search, comparison and routing to people, with the commercial layer designed as part of the interface rather than bolted onto it.
