A nationwide survey conducted by the National Association of Home Builders at the end of last year ranked the hottest trends for 2016 in terms of must-have's for the new construction of single-family homes.As builders observe their customers' demand and need for homes that include certain features more than others, their view on trends serves as a reliable gauge of the consumers' preferences.The survey that ranked most preferences from layout design to finish on a scale from one to five, showed energy conservation and efficiency features to be the standard for new homes being built this year: energy star appliances, high efficiency European boilers that vent out through the foundation walls and no longer require the presence of a chimney, low-e windows, and high-end digital thermostats that now can be controlled from anywhere you may be through your smart phone.WALK-IN CLOSETSWith an average rating of 4.9, walk-in closets in master bedrooms are definitely must-have's for new homeowners. Say goodbye to the miniature closet spaces that most turn-of-the-century building in Boston feature! LAUNDRY ROOMSThis year it turns out that even in-unit laundry rooms are very attractive features most buyers seek. Well, in fact, having to bring your heavy laundry bag all the way down to a cold basement more often than not (does that ring a bell?) isn't everyone's cup of tea. This feature ranked at 4.8!GREAT ROOMSThe next feature that in reality has been very popular for well over a decade is a great room, or a space in the home that combines the specific functions of the now old-fashioned rooms such as a living room, a dining room, a study area and a family room. It is one big unified space, which we have come to know as the open layout or open space plan. Who doesn't love that? Great for entertaining guests but in my opinion, not as great when you love to cook and the smell of food will travel everywhere even with a commercial-grade hood working at full speed above your stove.Lastly, spacious kitchens with central islands, granite countertops and stainless steel energy-rated appliances that by now are standard features for all brand new construction or remodeled existing homes, and 9'+ ceilings, received a high rating in the mid-4's.
