Support and Ongoing Development of the Olymp Residential Complex Website
Real EstateA case study of technical support for a real estate developer website on 1C-Bitrix: apartment catalog, interactive floor plans, and feature improvements without risking production stability.

Project Overview
PropTech / Real Estate • Web • Support and Evolutionary Development
Project type: a corporate website for a real estate development project built on 1C-Bitrix.
Format: a public-facing website for a residential complex with an apartment catalog, interactive floor plans, and lead generation forms.
Team role: technical support, feature improvements, bug fixing, performance optimization, and interface evolution.
About the Project
dom-olymp.ru is the official website of the Olymp residential complex and serves as the project’s main marketing and sales channel.
The platform brings together:
- presentation of the architectural vision and concept of the residential complex;
- an apartment catalog with key property details;
- interactive building and floor layouts;
- inquiry forms and viewing appointment requests;
- informational and marketing sections.
Our team supports the project in a long-term technical support format, ensuring reliable website operation, correct interactive behavior, and gradual improvements as business requirements and the development project evolve.
Business Goal
Primary objective: keep the website operating as a key real estate sales tool by maintaining stability, page speed, content relevance, and a convenient user experience for prospective buyers.
Support goals:
- Maintain reliable operation of all pages and interactive elements
- Fix bugs and technical issues in a timely manner
- Adapt the website to new materials, promotions, and project updates
- Improve UX without rebuilding the website from scratch
- Ensure correct operation across devices and browsers
- Enhance interactive features: floor plans, filters, and apartment selection flows
What We Do Within Ongoing Support
As part of the support process, we:
- Monitor website and server-side health
- Fix frontend issues and 1C-Bitrix logic errors
- Improve interactive floor plans and apartment catalog features
- Update content, images, and copy
- Optimize page load speed and caching behavior
- Adjust inquiry forms and integrations
- Adapt layouts for new devices and screen resolutions
- Implement new visual elements and animations
- Consult the client on website evolution options within the Bitrix ecosystem
Key Website Sections
From a support perspective, we work with the following modules:
- Homepage — visual blocks, navigation, and key project highlights
- Apartment catalog — filtering, property cards, and status management
- Floor and building layouts — interactive diagrams
- Interactive apartment selection
- Feedback forms and viewing appointment requests
- Contacts, infrastructure, and maps
- News and marketing pages
Special attention is given to the correct operation of interactive floor plans and the apartment selection logic.
Workflow
Support is organized as a continuous and controlled process:
Request Intake
We log the task and clarify the business objective.
Analysis
We assess the impact of changes on Bitrix, composite caching, and existing mechanics.
Development
We implement focused improvements without putting production stability at risk.
Testing
We validate user scenarios, cross-browser compatibility, and responsive behavior.
Release and Monitoring
We deploy updates in stages and monitor stability after release.
Challenges
Key challenges:
- •working within a 1C-Bitrix environment with custom modifications;
- •complex interactive floor plans and apartment selection logic;
- •dependency on Bitrix composite caching;
- •the need for careful changes without breaking existing functionality;
- •maintaining compatibility across different browsers and devices.
How we address them:
- staged releases instead of large-scale updates;
- mandatory regression testing;
- careful monitoring of composite cache behavior;
- backups before changes;
- targeted improvements instead of global refactoring.
