It’s the perfect choice for the larger family who appreciates spaciousness, logical room layout and smart extras that make everyday life smooth and enjoyable.
The interior of the Iris will surprise you with its thoughtful layout, offering plenty of space for living, relaxing, working and storing everything you need. A spacious living room, a large kitchen and a spacious terrace form a cohesive, functional whole that supports an active and comfortable family life all year round.

Everything you need and more
Iris’s standard layout has four bedrooms, a study, separate wardrobes and two separate storage rooms to help keep your home tidy even for a large family. A large bathroom, plus a separate toilet, ensure that morning rush hour runs smoothly. There is also a handy utility room and a spacious utility room that can accommodate all the necessary systems and seasonal accessories.
A pleasant atmosphere in all seasons
At the centre of the house is a large living room with a fireplace and floor-to-ceiling windows that create a bright and inviting atmosphere. The open-plan kitchen connects to the living room into a single, well-functioning area where the family can cook, play and relax together. Direct access from the living room to the 34 m² terrace provides a great place to enjoy summer evenings, morning coffee and family gatherings in the fresh air.

Top-quality materials
We use both high-quality cross-laminated timber (CLT) and a wooden frame to build Iris houses, ensuring you get the best solution.
CLT cross-laminated timber
Innovative CLT (cross-laminated timber) is five times lighter than concrete, but just as strong. As a renewable material, CLT wood binds CO2 throughout its lifetime, provides an excellent indoor climate thanks to its good thermal conductivity, and helps distribute moisture evenly throughout the building, which is especially important for people with allergies and asthma. In addition, layered CLT wood acts as a good fire barrier and provides uniform sound insulation.
Wooden frame
Traditional timber framing is a flexible and cost-effective solution. Timber framing allows you to build a house quickly and customize it according to your wishes and specific requirements. Thanks to high-quality insulation materials, timber frame houses are very energy efficient, keeping heating costs low. Timber is also used optimally in frame construction to build as resource-efficiently as possible.

Green house
An Iris house is a future-proof choice that will help you live smarter and more sustainably. Thanks to innovative technologies and environmentally friendly extras, you can reduce your energy consumption and make your home even more economical.
With its energy-efficient design and high quality insulation materials, Kerttu House is already an A-rated building with low heating costs. As standard, the building has a cost-effective air-to-water heat pump with underfloor heating, which you can replace with geothermal heating if you wish. In addition, we use energy-efficient forced ventilation with heat recovery.
Solar panels can also be installed as part of the construction process to help cover a large proportion of the home’s electricity bills, especially in the summer months when daylight is at its peak. It is also possible to add an electric car charging point, video and security systems, lighting for the exterior façade or other extras to make your new home more comfortable.
Your dream home
A house must be the face of its owner and every building we build has its own character. To ensure that your new home fits everyone’s needs, we have the flexibility to change the plans during the design process and tailor them to your wishes. Thanks to the quality of our production and the properties of our materials, we only need a few days to install the building. For you, this means shorter waiting times, significant financial savings and better quality.
