Passive Woodline© Transform

„Passive Woodline© Transform” is the second project out of the prefab passive timber frame houses „Passive Woodline©” series. The project represents a single family two-storey passive house.

The assembled sun protection system on the south façade adapts the house to the seasonal climatic changes. During the hot summer the sun protection panels unfold to prevent the house from overheating. During the cold winter the panels are folded, not to overshadow the south façade windows and to enable the natural warming up of the rooms.

You can look trough more detailed information and prices for construction by downloading the house’s catalogue.

Basic principles of Passive Woodline© Transform:
  • passive house
  • prefabricated
  • high living comfort
  • high quality
  • low cost
  • construction in 60 days
  • sustainable construction
  • contemporary design
Why prefab?

The passive house construction tends to become faster executed, cheaper, more ecological and with higher quality. As a result, the timber structures and the prefab construction make their way into the passive house construction process. However, the prefab passive construction is still mistrusted in Bulgaria.

Why high living comfort?

Living comfort is one of the basic principles of the passive house standard. The temperature of the enclosing elements of the passive house is close to the temperature of the interior air which leads to high heat comfort. High acoustic comfort is achieved due to higher acoustic qualities of the enclosing elements of the passive house in comparison with those of the conventional house.

Why high quality?

The basic advantage of prefab construction is the process of producing structural and non-bearing building elements in factories in advance. Prefab building elements have higher qualities in comparison to producing them on site. Because of that, prefab building structures are precisely executed and have high aesthetic quality.

Why low cost?

On average, passive houses are still up to 15% more expensive than conventional houses. This percentage decreases in the cases in which the passive house is with prefab timber construction.

Why construction in 60 days?

Prefab constructions together with the lack of the wet, non-ecological concrete elements’ execution on site allow the construction process to be executed in two months.

Why sustainable construction?

During the planning of „Passive Woodline© Transform” a number of environmentally-conscious techniques were used in order to achieving the principles of sustainable construction. Prefab construction presupposes minimal negative impact on site.
Wood is ecological building material which is highly valued according to the list of sustainable construction materials. This is the reason why, in the project, wood is used not only as structural building material but as non-bearing building material as well.
A rainwater collection system is designed. The house has heat recovery ventilation system. Sun collectors for domestic hot water, low-energy lighting and high efficiency electrical appliances are used to lower total primary energy consumption.

Why contemporary design?

Most people believe that prefab timber construction does not equal to design and quality. The main aim of this project is to change the negative image of prefabricated construction.

Functional scheme:

The house’s entrance is North oriented. A building for garage and storage room is designed also to the North. The South part of the Ground floor consists of living room, dinning room and a separate kitchen. There are also entrance-hall with a staircase, laundry room, technical room, toilet and larder to the North.
On the First floor there are three south oriented bedrooms. The master bedroom is with a private bathroom. Every bedroom has a private closet.
