CASAI stands for a Completely New Way to Plan Your Home
For many people, building a house is a lifelong dream and also the biggest investment they will ever make. The early stages of planning a house are often characterised by uncertainty and many questions – often long before any concrete decisions can be made.
This is exactly where CASAI comes in: with CASAI, the Oikos Group has created a unique solution that revolutionises and significantly simplifies the start of the house-planning process. Wishes and ideas can be incorporated at an early stage and translated into concrete house concepts – available at any time, anywhere, and usable without prior knowledge.


Digital Advisor for Home Building
CASAI accompanies you step by step on your journey to owning your own home. Through a simple, dialogue-oriented exchange, your wishes, ideas, and questions are incorporated directly into the planning process. Architecture, living style, room layout, and budget can be intuitively defined and adjusted at any time – without fixed procedures or prior knowledge.
Design options, floor plan variants, and cost implications become immediately visible and easy to understand. Gradually, an individual house concept emerges that reflects your ideas and can be downloaded as a clear exposé – providing a sound basis for the next steps in the house-building process.

Cross-Brand Expertise of the Oikos Group
As a digital component of the Oikos Group, CASAI brings together the expertise of the Group’s brands and makes it digitally accessible for the first time.
The proposals developed are based on proven house concepts and furnishing options from the brand portfolio and utilise the experience gained from more than 10,000 completed house construction projects by Hanse Haus, Bien-Zenker, and Living Haus to realistically and reliably reflect individual ideas.
With CASAI, the Oikos Group is setting a new digital standard in house construction. The AI-supported advisor combines innovative technology with reliable quality. At the same time, CASAI remains open to new technologies and is continuously being developed to respond to new requirements at an early stage and consistently advance digital house planning – Simple.
