Portal – Building Companion – a virtual assistant for house builders

case studies


As part of our cooperation with Xella, we have created a Building Companion open platform that helps individual clients build their dream home. The website was created as a corporate start-up within the structures of Xella — a top producer of concrete building blocks.



The main purpose of the project was to find an innovative path to reach target groups — people investing in construction and construction teams — and to increase sales of materials produced by Xella.



The website offers everything a beginner needs — a base of expert knowledge, a search engine for contractors (from architects to construction teams), a construction planner, access to a database of wholesalers and discounts on materials.


By creating a tool that brings together both target groups, engaging the community (rating and referral system) and offering special discounts, Xella has become the brand of first choice among local construction teams. Among investors, Xella has gained the image of an expert and reliable adviser. Additionally, the Building Companion platform has become a source of current information for Xella about the real needs and preferences of both groups. This allows the company to flexibly adjust the offer and even personalize it.


800,000 users used the platform, and 2,000 customers built their homes using the offers available on the Building Companion website. The system includes over 1,000 profiles of proven contractors and architects, and nearly 10,000 discount coupons for construction products.


The BC Platform won the bronze Innovation statuette in the category: Innovative Media, subcategory: Applications and Platforms.
