The types of buildings on display are extremely varied, ranging from school buildings and sports halls to family homes, apartment blocks and tourist apartments – all featuring wood in a variety of ways.

The increasing use of wood is an indicator of a growing awareness of the importance of sustainable, well designed buildings. With the right choice of wood, construction type and method, wooden constructions can fulfil the standards of modern sustainable buildings, decreasing environmental impact. During its growth and use, wood stores CO2. In addition, wood processing uses less energy than other types of materials. Wood construction is faster, more energy efficient and more user-friendly than traditional building methods.

Wood buildings have a positive influence on our well-being and offer a high degree of living comfort. Education in these buildings fosters creativity and learning motivation.

Nowadays it is increasingly important to recognise the value of quality built space which develops aesthetical and functional standards of dwelling culture in harmony with the state-of-the-art technology, environment and climate change. The European Commission initiative “The New European Bauhaus”, which aims to accelerate the green transformation, also sees architects and architecture as the pivotal force of the transition to a more sustainable economy and society.

OHS links sustainability to outstanding architecture and offers practical solutions for a life in symbiosis with nature. The use of wood in architecture and interior design is the right answer for a green future, and for a better, greener and more humane 21st century.

A new Science Centre is planned to be built in Ljubljana by 2023 under the auspices of the Ministry of Education, Science and Sport. The vision of the demonstration facility of state-of-the-art technological solutions and innovations is to stimulate curiosity, new ideas and innovation. It will be a crossroads of cooperation between science, education, economy and culture. The Science Centre will offer the opportunity to set up do-it-yourself and science promotion programs related to education, culture and the economy, encouraging young people to research, think and find answers, thus popularizing science, research and creativity. At the same time, the new building will enable all top solutions of Slovenian scientists and researchers to be presented in one place.

The Science Centre will help to accelerate the transfer of knowledge, technologies and innovations into practice, create new standards, raise awareness and expand the use of new technologies, as well as to obtain the first market references to the holders of new innovations.

Visualization of the new Science Centre: Dekleva Gregoric Architects

In 2018, the Ministry of Education, Science and Sport, in cooperation with Chamber of Architecture and Spatial Planning of Slovenia, announced an international architectural competition, which ended in February 2019, with the selected first-prize winning solution by Dekleva Gregorič Architects.

Involving and informing the public about the values of a quality built space is the basic mission of the aFront institute (organizes the Architectural Festival Open House Slovenia), which is a member of the program group for the construction of the Science Centre. Together with the investor (MIZŠ) and the producer of project documentation (Dekleva Gregorič arhitekti), we (aFront powered by GolemDigital) created a virtual presentation of the architectural design and key spaces of the Science Centre, in order to bring quality architecture to the general public.

The free application “We are building a new Science Centre” is also being prepared. With 360 ° views and an AR function, it will enable you to get to know the key spaces and architectural features of the new building on site. It will encourage the user to actively explore the built space in an interesting and modern way. The application represents one of the most innovative approaches to combining modern technology and presentation for educational purposes in Slovenia.

The following activities are currently underway:

  • preparation of project documentation, where the phases of IZP and IDP are completed, the phase of DGD begins
  • preparation of an amended draft of the municipal detailed spatial plan, which is ready for discussion at the City Council of the City of Ljubljana

Dear visitors, explorers and supporters of Slovenian architecture!

As you know, the 11th OHS festival of quality architecture was scheduled to open the doors of outstanding buildings across Slovenia this following weekend. Over 100 exceptional architects sent in their works, over 100 homeowners and building managers were contacted, 200 presentations were written and 50 volunteers were standing by. Our six member jury selected the best quality works to be presented during this year’s festival called »Architecture for future generations«.

We were prepared, but the covid-19 emergency disrupted our plans.

Nevertheless we decided to inaugurate our online festival on April 17, 2020, at 5 pm.


If mass events can safely be held this autumn, the festival will take place from 25th to 27th September, 2020, when you will be invited to vote for your favourite architecture to be awarded the OHS AWARD.

We are looking forward to your online visit of the selected buildings.

Until a treatment or a vaccine against the coronavirus is available, the physical space of architecture and design will remain THE MOST EFFICIENT SOLUTION for a healthy life.


Dear friends and visitors of Open House Slovenia!

Due to the current situation regarding the COVID-19 virus, we decided to postpone the festival. We want the festival to take place in a relaxed and healthy environment. The event is scheduled to take place from May 29 to May 31, 2020. We keep a close eye on the situation, so we will keep you informed about any changes.

Cities are one of the most important shared resources, that enable us to participate socially, meet and spontaneously interact, which is all fundamental to social life. This is not possible in the current situation, but we have no doubt that we will soon be able to meet again as residents, neighbours and researchers of architecture.

In the meantime, we invite you to visit our website and follow us on our social networks, and we will do our best to to bring you as much interesting content as possible.

Stay healthy and support people around you. When cities and buildings reopen, we will be with you again!

ISA 2019: Immersive School Of Architecture

6 days, 6 mentors and respectful architecture in the focus

This workshop is a rare opportunity in Europe to be immersed in the field of respectful architectural practice. ISA 2019 will be a week of learning new skills and schools of thought that are essential in creating architecture that is responsive to both its people and its place. All while expanding professional networks and basking in the spectacular Triglav National Park.

Through focussed design projects, participants will be encouraged to consider the increasingly important tools for design, including an ability to ‘read’ the land and its inhabitants, understanding the relevance of composition in the landscape, a confidence in the potential for the use of natural and sustainable materials, and to design with the human scale as a priority. The week-long workshop will be led by tutors Richard Leplastrier, Maruša Zorec and Peter Stutchbury, globally renowned for their responsive, thoughtful and sensitive design, and will be supported by a curated selection of guest critics and professionals from the industry, like Aleš Vodopivec, Aleksander Ostan and Matej Gašperič.

The workshop will take place from 11 to 16 April at Trenta, Triglav National Park.

Admission: 515 € per participant.
Early birds admission: 305 € (valid until 20.1.2019).

The number of participants is limited due to the intimate nature of the workshop and the need to work in small teams.
