Build Smarter.
Live Comfortably.
Pay Less.
We design and build high-performance homes using SIP panels, timber frames, and prefabricated systems — optimised for comfort, low energy consumption, and predictable long-term costs.

How we build
We work with the most effective modern construction technologies, chosen for performance, speed, and long-term durability.
Structural Insulated Panels deliver excellent insulation, rapid installation, and high energy performance for modern homes. The structure goes up in as few as 5–10 working days.
Timber structures offer natural thermal comfort, long-term durability, and efficient energy performance. An environmentally conscious choice that also delivers outstanding living quality.
Prefabricated elements allow fast construction of modern homes with controlled costs and consistently high energy efficiency — precision-built in factory conditions.
Steel structures provide high strength, stability, and maximum design flexibility for complex or large modern homes — robust, dimensionally accurate, and long-lasting.
Your home starts with The Plan
Most homes are built without a clear picture of real costs, energy use, or whether the chosen construction solutions are actually correct. We solve this before construction begins.
Discover exactly how much your home will consume, based on the chosen construction solutions and real-world scenarios.
Know in advance what your home will cost over time — construction, operation, maintenance, and consumption.
Every major decision is analysed, compared, and validated before construction — not corrected after at great expense.
A clear visual picture of your future home's shape and spatial logic before a single wall goes up.
Fully deductible if you choose to build with us. For a project worth tens or hundreds of thousands of euros, this is the investment that gives you control and clarity.
We calculate. We don't guess.
More than reduced energy bills
Designed to minimise heat loss and cut energy use throughout the year — in heating and cooling seasons alike.
High-performance insulation and smart design maintain stable indoor temperatures regardless of outside conditions.
Airtight construction limits uncontrolled air leakage, directly contributing to superior energy efficiency.
Modern ventilation systems ensure constant fresh, filtered air — a healthier environment for your family.
An energy-efficient home keeps its value over time — lower operating costs and a higher market position.
Modern construction methods mean the main structure is raised in just 5–10 working days, keeping your project on schedule.
A clear, simple process
We analyse your land, budget, and lifestyle to define the right performance level and direction.
Floor plans, renders, and a full energy simulation so you know exactly what you're building.
We build using the chosen technology. The main structure is raised in days, not months.
You receive your finished, energy-optimised home — with full documentation and verified performance.
What our clients say
"I was looking for a construction solution that could be built quickly, with good insulation and a fixed, transparent cost. After the foundation was done, the entire structure was finished in 10 working days. I didn't have to do anything extra or spend anything more."
"I chose a SIP panel house after a lot of research and it was one of the best decisions I've made. The construction was fast, clean and well organised. In just 5 working days I watched the house go up — ground floor and roof structure. Impressive."
"We worked with Happy Home for our SIP house and we're extremely happy with the result. The team was always there for us with solutions and ideas tailored to our needs. The house turned out exactly as we wanted — maybe even better."
Frequently asked questions
An energy-efficient home is designed and built to minimise heat loss and reduce energy consumption. Through the use of high-performance materials, correct insulation, and modern construction technologies, the home maintains high thermal comfort with significantly reduced energy use throughout the year.
The main advantages include substantially lower energy bills, superior year-round thermal comfort, better indoor air quality, a smaller environmental footprint, and higher long-term property value. Energy-efficient homes also tend to require less maintenance and age more gracefully than conventionally built homes.
We build using SIP panels (Structural Insulated Panels), timber frame structures, prefabricated systems, and steel frame construction. Each technology is selected based on the client's requirements, site conditions, budget, and the desired performance level. All our builds exceed current energy standards.
A passive house is the highest standardised level of energy efficiency. Our "Happy Passive Ready" level is designed to meet or approach this standard. Our other levels (NZEB Plus and Performance) also significantly exceed current building regulations while being more budget-accessible.
Most costly mistakes in home construction happen because decisions were made too early, without real data. The Plan gives you a complete picture — energy simulation, cost projections, and validated design decisions — before the first wall goes up. For a project worth tens or hundreds of thousands of euros, €1,500 for clarity and control is the best investment you can make. If you then choose to build with us, the fee is fully deductible.
