Without a family room, basement, or attic, Ana Bonilla’s clients wanted a place to play board games and to escape from the chaos of everyday life. The principal of AnaVera Design replaced the Newton Colonial’s shoddy three-season porch with an insulated sunroom with radiant heat flooring and sliders that open onto a new patio. The breezy decor makes it feel like a sanctuary, while the kitchenette and a banquette paired with a table provide additional function.

1 A midcentury-modern-style sofa comfortable enough for napping or watching television bridges indoor and outdoor sensibilities. Custom floral pillows dress up the white cushions with some island style.

2 Patricia Busso created the abstract landscape painting, which infuses vitality and complementary color. “The underpainting included huge cypress trees that I obliterated with a neutral sky,” says the Boston-based artist.

3 Nickel-gap boards bring coastal interest to the walls, draw the eye away from the slanted ceiling, and elongate the room. “The space needed some architectural detail,” Bonilla says.

4 Serena & Lily Luna Stripe wallpaper and floating shelves turn the utilitarian kitchenette into a statement feature. “The clients love to entertain,” Bonilla says. “The kitchenette services the patio when they grill.”

5 Bonilla designed the custom poufs. They’re made from an indoor/outdoor fabric and have faux leather bottoms so they can be pulled out to the patio.

6 Bonilla moved the coffee table from another room in the house. “The small scale is perfect here and the wood tone works well with the sofa,” she says.
