In modern societies, the group of people with dysfunctions related to the spectrum of autism is becoming increasingly numerous. A specialized approach to space design for this group of people is becoming a necessity. Particular attention should be paid to the rooms where children with autism spectrum disorders spend a lot of time - to classrooms. The arrangement of space can strongly influence their behavior. Special attention must be paid to the size and proportions of the room, the sense of order in space, proper sunshine, shading and ventilation, as well as to the reduction of detail, the excess of which leads to aggression and lack of concentration in this group of people. Another important element is the proper furnishing of the room, clearly informing about its purpose, or creation of clear zones.However, we are not always able (for procedural and financial reasons) to build complex daycare centers or schools for autistic people, and adaptations of existing rooms impose many limitations. However, despite this, at Tadeusz Kościuszko Primary School No. 11 with Integration Classes in Katowice, an original attempt was made to implement the above assumptions. It includes space zoning, floor differentiation, appropriate lighting, adequate equipment with the elements that are not typical for regular classrooms, as well as color markings and pictograms on the walls, which will be presented in more detail below. All this will undoubtedly lead to better comfort of use.

The article presents the effects of research on different types of models of single family houses and multifamily houses. Exterior layout and interior functional layout are the main drivers for the final result of a design. Models are an important medium for presentation of architectural designs and play a pivotal role in explaining the first idea to people and potential clients. Although 3D models have unlimited possibilities of representation, some people cannot understand or 'feel' the designed space. The authors try to test how to combine the interior and the exterior in a single synthetic model. Several models of different houses have been presented in the article. All the case studies were developed with physical models, 3D models, and 2D hand sketches. The main focus of the work with the models was to achieve a coherent vision for future feeling of open space in designed houses. The research shows how synthetic models might be helpful in the design process. The research was carried in the URBAN model research group (urbanmodel.org, Gliwice, Poland) that consists of academic researchers and architects. The models reflect architectural experience gathered by the authors during their work on theoretical models, architectural projects and by supervision on site during construction site visits. Conclusions might be helpful for developers, architects, interior designers and architecture students.

'Barn house' architecture can be presumed as a style or trend in contemporary architecture. The term 'barn-house' refers to a house that architecturally refers to barn with a simple, longitudinal form with pitched roof. Originally, barns were converted to houses for practical reasons. Later on, the design aspect was getting more important and any house or any barn were not enough, and so it turned to be a style which can be described as 'designed barn-house'. The idea appears to be well-recognized: many built houses and house designs represent that style. Also, several online blogs on that subject have been created and published dozens of examples. We may presume that many contemporary architects have either already designed or are aware of designing a barn-house. The reason for that is mostly simplicity of architecture, and lack of details which are common in contemporary architecture. 3 case studies of barn-type house designs have been presented in the article. All of them have been designed by the authors. All the concepts have been designed using synthetic models: physical and virtual. The open space concept can be recognized in all the three case studies: the interior layout seems to be more important than the exterior in that kind of architecture. The authors conclude that some uniform rules can be recognized in barn-type architecture design. However, many concepts have gone far beyond the original barn-house idea. The question is whether that trend can be presumed as distinctive?

Contemporary LED technology in lighting industry allows today for almost endless design opportunities in architecture. Since 2000 the LED strip lighting became available on the lighting equipment market and slowly became affordable as the typical light source (bulbs) or linear light source (neon bulbs). Today it is implemented everywhere around the globe in exterior and interior design. Technological solutions are even more portable / easy-fixed and take less space and so linear lighting is not extraordinary or exceptional anymore. Although the linear lighting became very common since ca 10 years it have been used in interior or exterior design before but had some limits due to the technological reasons or have been implemented in another way. Design Lighting typology for interior and exterior design has been presented in the article along with several case studies that have been implemented. Limits and obstacles, advantages and disadvantages of the linear lighting have been discussed. Conclusions might be helpful for architects, interior designers, artists and light industry specialists. The author is a practicing architect with over ten years of experience in architectural and interior design with many implemented projects.
