The situation before

The MWW Mieszkanie estate agency in Łódź is run by a University of Łódź law graduate, estate agent and member of the agents' association. It handles sales, lettings, cash purchases and valuations, and also sells the Plażowa Park and Leśna Ostoja developments.

Listings reached buyers through property portals, where the pace of publishing and corrections depended on an outside system. The brief covered the agency's own site with a page for each service, a property catalogue and a panel for publishing listings in house. A section with both developments the agency sells was added later.

Questions the project had to answer

What gives each of the agency's services its own page that clients can find through a search engine?
How should the homes from both developments be presented, each with its plan position and its own card?

How we did it

Services and listings
The site runs on Vercel, and the catalogue and panel share one listings database in Supabase. The services went onto six pages, from sales and lettings to cash purchase, new-build stock, off-market properties and valuation. The catalogue filters by transaction type, category, location, price, floor area and rooms, and orders results by price or size.
The location field searches addresses, streets, towns and districts, and featured listings carry a star and appear first. Every listing has a readable address built from its title and a photo gallery. When a pin is set, it also shows a map with a route link in Google Maps. A PDF button turns it into an A4 sheet with the first photo and the print date.
Every service page has a section of frequently asked questions and ends with an invitation to talk. The home page form lets visitors choose the topic of their enquiry and collects marketing consent separately from consent to a reply.
A panel for the agency
In the panel the agency fills in one form, drags photographs in and sets the location with a pin on a map. A location can also be found by address and corrected by dragging the pin. A similar listing can be copied with its photographs. The panel then reminds the agency to check the title, price, floor area, address, pin, description and photographs before saving. A half-finished form saves itself for a day.
Photographs straight off a camera are reduced on upload, and the server stores them in lighter formats with a thumbnail for the catalogue. A listing therefore opens quickly on a client's phone too. Listings can be hidden or featured, and live ones feed the sitemap for search engines automatically. The panel's list of listings has a search box and a filter for active and hidden ones.
Developments section
The Developments section presents both estates the agency sells, the 16 flats and 4 houses of Plażowa Park and the 12 houses of Leśna Ostoja. Every home has a card with its floor area, plans and position on the site plan, and the lists of homes can be filtered and sorted. The Leśna Ostoja plan is a drone photo with clickable houses. Data for both estates sits in one file, so changing a price or status takes one line.
On the Plażowa Park plan, sold homes are hatched and reserved ones darkened. In Leśna Ostoja, pointing at a house highlights its roof and garden. Each estate has a gallery, a specification and its own enquiry form, and the section's main page shows both estates and the office on one map.
