Urbany also pointed out the importance of smart home technology. "Anyone with a smartphone or voice-activated speakers, like Amazon Echo or Google Home, knows the convenience of home features that can be controlled via a simple swipe, utterance, or in-home video panel," the architect said.

"Not only are these features convenient, but many — including lighting and heating/cooling control — can reap real rewards on monthly utility bills. For architects, the challenge becomes creating spaces to house any mechanicals and the necessary wiring that goes along with them."

Another important aspect of contemporary architecture is sustainability. After all, according to the U.S. Energy Information Administration (EIA), buildings generate nearly 40% of annual global GHG emissions.

"It's no surprise the trend is towards creating more energy-efficient buildings, but also to develop homes that use, and leak less energy," Urbany explained.

"The pinnacle of this type of design is a net-zero home that literally has no net energy consumption. This is achieved by not only reducing energy consumption but by adding energy creation on the site, typically in the form of solar panels."

Even if net-zero is too lofty a goal, architects are urged to implement as many sustainable features as possible. These include well-sealed building envelopes, efficient insulation, multi-panel windows, and energy-efficient appliances and systems.

TMD STUDIO, a London-and-Prague-based group of young professionals operating within the fields of architecture, visualizations, interior design, and research, agrees that sustainable architecture holds the key to an environmentally positive future.

"Only by living more economically with our resources can we hope to protect our environment and climate," TMD STUDIO wrote.

"By keeping the energy we consume within our buildings for as long as possible, we need less supply in the first place," TMD STUDIO said. "Using less energy to keep us comfortable means that we can become environmentally responsible and more resource-efficient, which are both vital to reducing the effects of climate change."

According to the organization, there are three overriding concerns when designing buildings with better considerations towards ecological impact: the first is the materials used for construction, the second concern is the energy efficiency of the building and the last factor to consider is the location of the building itself.

"The building might be energy efficient and use low impact construction technologies but this would not mean anything if the ecosystem suffers as a result of the building. A greater holistic approach to all of these design factors is becoming more prevalent in mainstream architecture."

Urbany said that housing multiple generations of one's family under one roof was commonplace before the middle of the last century, but after WWII, single-family homes became more popular, spurred by the post-war boom and desire to achieve the American Dream.

"Today, people are living much longer which has created a so-called 'sandwich generation' that's both caring for young children and older parents. Therefore, the demand for housing with features that cater to multi-gen living is growing. According to the AIA survey, the most popular features include first-floor master suites, elevators, and laundry facilities on multiple levels, all of which can be found in Dixon Leasing's extensive portfolio."
