Africa's first certified Active House.
When cutting-edge architecture meets cutting-edge technology, a new way of living takes shape.
Design Principles
Architecture as a Performance System
By using technologically advanced materials that, while offering the same structural efficiency, weigh only a quarter as much as traditional materials, we push the boundaries of conventional architecture to create large, elegant spaces and volumes, and high-performance floor-to-ceiling glass walls covering approximately 160 sqm.
European construction Technology
Developed in Europe almost 40 years ago, this set of technologies pushes residential construction into the future.
Designed to maximise the health and comfort of a home year-round, it drastically reduces construction time, revolutionises construction techniques with engineered, fully renewable materials, and achieves a clean energy surplus from entirely renewable sources.
Where comfort and health coexist
Comfort is a complex issue that, when addressed scientifically, enables a healthy environment free of humidity, cold spots, and temperature fluctuations. All this translates into a better quality of life by “leaving outside” the causes of respiratory problems such as asthma, coughs, bronchitis, allergies, and infections, as recommended by the World Health Organisation

Understanding the Technology
Key questions and clear answers on the technology behind the system.
Why does iTechHouse look so attractive?
Our first priority is to identify the right site. Sun exposure, space, vegetation, and the natural shape of the land are essential elements in developing our architectural principles.
For iTechHouse in Hout Bay, we chose not to maximise the buildable area, limiting the home’s footprint to less than 20% of the plot. This decision reduces the impact on the land and preserves its original features, including natural boulders and existing vegetation.
The design follows the slope of the site, creating natural curves that establish a balanced relationship between the building and the landscape, setting it apart from conventional residential architecture in Cape Town.
By using technologically advanced materials that are much lighter than traditional ones while delivering high structural performance, we can move beyond some of the limits of conventional construction: larger spaces, elegant volumes, and full-height high-performance glazing designed to bring in light, comfort, and energy efficiency.
Why are we so fast?
Mass Timber changes the way a house is built. The project is first developed in 3D and coordinated through a BIM platform. The digital files are then sent directly to the factory, where CNC machines cut each panel and beam with millimetre-level precision.
This means that what is designed is what is produced, reducing uncertainty on site and allowing the structure to be assembled in days rather than months.
Because much of the process moves off-site, different phases can run in parallel: while the timber structure is being produced and shipped, the foundations can be prepared according to the same digital model and installation schedule.
This level of planning makes procurement, logistics and construction more precise, efficient and predictable, reducing construction times by up to 70% compared with traditional wet construction methods.
Why are we delivering comfort so easily?
Through our technologies, iTechHouse delivers what we call Controlled Comfort: a stable, pleasant indoor environment, protected from external conditions such as heat, cold, wind, rain and noise.
At the heart of this performance is the thermal envelope, one of the most hidden yet valuable parts of the house. It works like an invisible protective layer, combining ventilated façade, insulation, airtightness, high-performance glazing, ventilation and underfloor heating.
Together, these elements create a calmer, healthier and more comfortable home, where comfort is not left to chance but designed into the building itself.
Why is an Integrated technology so essential?
To deliver both Controlled Comfort and construction efficiency, iTechHouse changes the way a home is built: from design and materials to assembly.
The key shift is from wet to dry construction. Apart from the foundations, dry construction avoids the use of water-based processes such as concrete pouring, brickwork and mortar. This moves much of the work from the construction site to a controlled off-site process.
With Mass Timber as the load-bearing structure, different phases can be planned and executed in parallel. Once the structure is assembled, the thermal envelope, building systems and interiors can follow with greater precision, speed and predictability.
Why is iTechHouse so healthy?
Indoor comfort has a direct impact on well-being. Unstable temperatures, draughts, humidity and poor air quality are associated with respiratory discomfort and other health-related issues.
iTechHouse is designed to reduce these risks through Controlled Comfort: a stable indoor environment, filtered air and certified low-emission materials, in line with international guidelines for healthier buildings.
Wood also plays an essential role in this experience. It brings warmth, softness and a natural sense of well-being that conventional materials cannot easily provide. Over time, even its scent becomes part of the character of the home.
Why is it so truly green?
iTechHouse addresses sustainability through two essential entities: embodied carbon and operational carbon.
Embodied carbon refers to the greenhouse gas emissions generated before and during construction, including the production, transport, installation, maintenance and end-of-life treatment of building materials.
Mass Timber helps reduce this impact because it comes from a renewable natural resource: trees from certified, sustainably managed forests. Unlike concrete, which relies on extracted non-renewable materials and carbon-intensive industrial processes, wood stores carbon absorbed during the tree’s growth and can be regenerated over time.
Operational carbon refers to the emissions generated by the energy a building uses throughout its life, including heating, cooling, lighting, ventilation and appliances.
This is where the thermal envelope becomes essential. By protecting the indoor environment from external conditions and reducing energy loss, it lowers the amount of energy needed to maintain comfort inside the home.
Why are running costs so low?
Since the thermal envelope marks the point at which thermal dispersion is minimised, we can achieve energy savings of around 70%.
How can we turn a house into a Power Bank?
By reducing energy demand by around 70% and combining this efficiency with optimal solar exposure, photovoltaic panels, heat pumps and battery storage, iTechHouse can move beyond low consumption and begin to generate usable energy surplus.
At this point, the home becomes more than an efficient building: it becomes an energy reserve, capable of supporting daily living needs and contributing to electric mobility.
What can we do with an energy surplus?
Energy independence is becoming an increasingly valuable feature in modern homes. When the house generates more energy than it consumes, the surplus can be stored, used to support daily household needs, or directed towards electric mobility.
Connected to an electric vehicle, this surplus energy can help reduce both mobility costs and operating emissions, turning the home into an active part of a cleaner and more efficient lifestyle.
What does it mean to own an Active House?
Active House is first and foremost an internationally recognised certification and one of the most comprehensive and demanding standards in residential construction. It evaluates a home across three key areas: Comfort, Energy, and Environment. Rather than focusing on energy performance alone, Active House measures how a building supports the health and wellbeing of its occupants while minimising its environmental impact. Achieving Active House certification means meeting strict performance criteria and demonstrating a balanced approach to sustainable, healthy, and comfortable living.
