“We are approaching the first 1,000 days spent in our family home designed by your Createrra studio. After 990 days of continuous operation of the PKOM4 Classic unit, we have recorded a total energy consumption of 5,086 kWh, covering ventilation, heating, cooling, and domestic hot water preparation. For our floor area, this means an annual consumption of just under 18 kWh/m²—while maintaining comfortable conditions: winter heating at 22–23 °C and summer cooling at 25 °C. If my calculations are correct, even without the PV system, this would mean energy costs (excluding cooking and lighting) of up to €30 per month.”

“Even after several years, living in the house is excellent, and we truly enjoy it. The indoor climate remains pleasant, whether it’s summer or winter. Often, we hardly feel like going outside. We chose Createrra because we were impressed by their previous projects and their approach to passive houses and sustainable building. From the very beginning, collaboration went very smoothly; we were open to new ideas and welcomed the advice of experienced architects. We were often pleasantly surprised by their solutions. We greatly appreciate that the collaboration continued throughout the construction of the house as well.”

“Living in a passive house is primarily about thermal comfort. What does that mean? Consistency. Minimal temperature fluctuations. Warm in winter, pleasantly cool in summer. Working with Createrra was excellent. From the very beginning until the handover—not only of the architectural documentation, but also during construction—whenever the contractor was unsure, they knew exactly whom to call and always received the answers they needed.”

“Working with Createrra has been very open and fair from the very beginning. Many times, Createrra went above and beyond when we needed to consult something or changed the concept multiple times. We never encountered a negative reaction. This is a team of professionals who know exactly what they are doing, but above all, they are capable and willing to listen to the client. We truly appreciated that.”
