Residential Complex DIADANS
Real estate
diadans.ua/ DIADANS is a residential complex that needed more than a throwaway landing page - it required a full-featured website built for long-term advertising campaigns. The site had to actively sell, not just showcase: with a conversion-focused structure we iteratively refined based on ad performance data, every lead passed to CRM with full advertising context, and a 3D walkthrough of the grounds to lower the barrier to a first visit. Additional requirements included multilingual support (UA/RU/EN) and responsive design prioritizing mobile devices, which drive the bulk of ad traffic.
Task
Design, develop UX/UI, and deliver the full development cycle for the DIADANS website with a conversion architecture. Launch ad campaigns, run a series of A/B tests on structure and CTA elements, and lock in the highest-converting variant. Integrate Flatris for interactive apartment selection, connect CRM with Google Sheets integration via Apps Script for parallel lead capture, and ensure end-to-end UTM tag pass-through from the first ad click to inquiry submission. Embed a 3D territory tour, optimize page load speed, and build a trilingual interface.
What was done
- Designed UX/UI with a conversion-driven structure: block sequence follows the buyer's decision funnel - from an emotional hero screen through benefits, infrastructure, and floor plans to contact forms.
- Built the site on pure PHP with a lightweight architecture free of framework dependencies - minimal server overhead for fast loading under heavy ad traffic.
- Conducted a series of A/B tests: variations in CTA placement, section order, headline copy, and form field count - selecting the highest-performing combinations based on real conversion data.
- Integrated Flatris for interactive apartment selection: buyers pick a section, floor, and unit on a visual building schematic with layout, area, and pricing displayed.
- Embedded a 3D tour with a virtual walkthrough of the complex grounds for remote exploration without a physical visit.
- Implemented end-to-end UTM pass-through: ad source parameters persist across page navigation and are submitted with every inquiry - marketing sees exactly which ad brought each lead.
- Connected CRM with automatic lead submission and Google Sheets integration via Apps Script: each inquiry is simultaneously logged in a cloud spreadsheet with full data - contact, selected apartment, UTM tags, date and time - giving the sales team instant access without logging into the CRM.
- Optimized page load speed: CSS/JS minification, image compression, server-side caching - keeping bounce rates low for ad-driven traffic.
- Built a trilingual interface (UA/RU/EN) with proper URL structure for each language.
- Delivered mobile-first responsive layouts: enlarged tap targets, simplified navigation, forms optimized for phone input.
