<title>Open Door Day in a Modern Wooden Building Near Karlštejn</title> Open Door Day in a Modern Wooden Building Near Karlštejn

You can come to see a modern energy-efficient wooden building, built in the village of Halouny, with your own eyes on Saturday, October 20, 2012, between 9 AM and 5 PM. Representatives of the NOVATOP system and the implementing company 3AE will be ready to answer your questions. The homeowners will also be present and will gladly share their experiences with the construction and use of the house. If you are planning to build, this is definitely a unique opportunity to get firsthand information.

If you are interested and have any questions, please contact the organizer: the company 3AE, team@3ae.cz, tel.: 777 285 844
You can enhance your visit to the house by visiting a second construction or taking a trip to the nearby surroundings.

The Story of the House
The intention of the young couple with a child was to move from a small apartment in Prague to a house farther away from civilization. They wanted to build a single-storey house that would be close to nature in terms of its philosophy – environmentally friendly in both the materials used and its operation. From the beginning, they had a clear idea of how their new home for a four-member family should function.

First Sketches
How did the architect, Ing. arch. Lukáš Pejsar, handle the assignment and the narrow elongated plot on the northern slope, oriented from south to north?

“I sought inspiration in nature, specifically in the fallen trunk of an old tree. That was the basic idea. I applied it to the surrounding terrain and the elongated plot at the foot of the northern slope. The effort was to design a house that would blend with nature and not draw attention to itself. I decided to partially ‘embed’ the house into the terrain while cantilevering part of it above ground, allowing for a beautiful view of the landscape despite the building being single-storey.

The materials have been chosen to ensure that the house is in harmony with nature and fits gently into it. The structure consists of solid all-wood panels made from NOVATOP laminated wood (you can see how the construction proceeded here). The facade is therefore made of unprocessed Siberian larch to achieve a natural patina. Part of the cladding is dark-colored, which was achieved by charring the wood. The original intention was also to have a flat roof with vegetation on the house. Unfortunately, this idea was not met with understanding from the local authorities, resulting in a variant with a specifically shaped gabled roof. I then chose metal roofing in a dark gray color.

Thanks to the client's accommodating attitude, I was also able to implement maximum use of wood in the interior, where the walls consist largely of NOVATOP visible panels. The house has a simple and clear layout. The backbone of the building is a corridor running through the entire house, to which individual rooms are ‘hung.’ This communication space leads to the living room, which is adjacent to the study. From the living room, bedroom, and corridor, there is access to the garden. The connection of this space to the exterior is emphasized by a panoramic window with a beautiful view of the valley.”




An important part of modern houses is also technology. The warmth of the home is provided by underfloor heating. However, the heart of the house is the accumulation tank fed by an air-to-water heat pump with the possibility of connecting solar panels. These will be installed in the future, and for now, only the preparation for their installation has been made in the house.

Technical parameters of the building:
Built-up area: 154.5 m2
Usable area: 128 m2
Built volume: 353 m3
External wall: U = 0.15
Floor above ground: U = 0.15
Roof: U = 0.14
Ventilation: Natural through windows
Heating: Hot water underfloor
Windows: Wooden Profile IV92 PASSIVE, Uw = 0.69
Shading: Preparation for exterior blinds
Heat demand for heating: 44 kWh/m2.a (PHPP)

A total of 240 mm of thermal insulation is used in the outer wall.
