Students at the School of Engineering, RMIT University recently published a study experimenting with a new form of waste management and recycling. As they note in their research, cigarette butts are the most commonly discarded single waste item in the world, with an estimated 5.7 trillion having been consumed around the globe in 2016. However, the materials in cigarette butts—particularly their cellulose acetate filters—can be extremely harmful to the environment due to poor biodegradability. The RMIT study builds on a previous research study by Mohajerani et. al (2016) that experimented with adding discarded cigarette butts to clay bricks for architectural use. In their research, the RMIT students found that such a measure would reduce the energy consumption of the brick production process and lower the thermal conductivity of the bricks, but that other issues including bacterial contamination would have to be addressed prior to successful implementation. Below, we explore this research in more detail, investigating its relevance to the architecture industry and imagining possible futures of application.

As much as walls, ceilings, and furniture pieces define the character and perception of an architectural project, doors play a critical role in building that style. Among all the doors used in houses, the front door is the first tangible element that homeowners and visitors will encounter, acting as the pivotal point where architecture greets the user. After all, first impressions are always important; and the entrance door is certainly one that can set the tone for the rest of the interior. However, choosing the right front door for a contemporary house can be difficult, especially with so many design possibilities. Therefore, before making that decision, it is crucial to know what those possibilities are – and how these can transform the front door into a design statement.

Faced with the challenge of designing homes on terrains with steep slopes - or in compact urban contexts that do not allow much variation in plan - several architects have experimented and proposed split-level homes to enhance the use of space, allowing, among other things, interesting visual perspectives.

These variations can be seen in numerous examples published on our site. Below, we have selected 50 examples that can help you in your next project.
