The Coveted Three-season Room


Here in New England, the month of October brings brilliant fall foliage and shorter, crisper days. It is the time of year when we layer sweaters, watch football and appreciate all things autumn. While many of our clients welcome this seasonal change, they are not quite ready to give up their outdoor living spaces. This is when a three-season room is a wonderful option.

Easing the transition between indoors and out, the great room opens to a shingle-clad three-season porch.

The three-season room, sometimes called a sunroom or solarium (Latin for “place of sunlight”), is typically enclosed in glass and provides homeowners with an immediate visual connection to the outdoors. The use of large window areas helps optimize the amount of natural light filling the room – providing a marvelous “outdoor” aesthetic. As the days get shorter, this access to light is especially appreciated.

Solarium is Latin for “place of sun[light]”

We often design our three-season rooms with screened-in windows that can be replaced with storm panels as the seasons change. This offers homeowners a space with great versatility: in warmer months, the summer air can circulate, and when temperatures dip, the windows protect from elements like wind and rain.

When the temperature becomes cooler, screens can be replaced…
…with glass, extending the porch season into the fall.

While not fully heated like a year-round room, we often design our sunrooms to include radiant heat and a fireplace, which adds ambiance while entertaining or gathering on a cool fall night. The cozy space offers a connection with nature without leaving the house.

A fireplace and radiant heat from bluestone floors offer homeowners added comfort in chilly weather.

Sometimes, a client will request that we transition a three-season room into a year-round room. In this case, we will use permanent casement windows (which can open out 90% in summer months) surrounded by beaded board or wainscoting to give the sense the porch was enclosed over time.

A year-round porch uses high performing, energy-efficient windows.

As the days get cooler and shorter, we appreciate the wonderful versatility of a three-season room, which affords homeowners with extra sunlight, protection from the elements and effortlessly extends the outdoor living season.
