There are few times of year more breathtaking than autumn in New England, particularly with its kaleidoscope of falling leaves in every conceivable shade of orange, yellow, and red. But for one family, the love affair with nature is all year round.Just about two hours from their primary residence in Boston, interior designer Nina Farmers clients found the perfect 1.6-acre plot of lakeside land in New Hampshire to build a modest vacation homea place the family of five could retreat to whenever inspiration strikes.Theyre a very active familywith three children in their upper teenswho go for swims in the lake every morning, climb the nearby mountain, and basically take advantage of everything the property has to offer, says Farmer, whose eponymous Boston-based interiors firm outfitted the familys retreat to mirror its laid-back lifestyle.David MitchellCompleted last year and conceived by Cambridge-based architecture firm Charles R. Myer & Partners, the red cedar Shingle-Style 5,400-square-foot main housewith its screened-in wrap-around porch and idyllic lake viewsfeels as though it could have had a starring role in On Golden Pond and that Henry Fonda and Katherine Hepburn might just row out from behind the towering pines at any moment. The house is very typical for the region, explains Farmer. And [for a ground-up build] it was important to them that it fit with the local vernacular.That sense of belonging also meant the interiors needed to reflect whats on the outside. They didnt want it to feel like a massive new construction home might, so they were very thoughtful about the layout and wanting it to feel like a very cozy space.David MitchellApplying her design philosophy to the full three-bedroom, three-bathroom propertywhich also includes a second story that houses a generous bunk room and an additional full bathroom, making it possible to host another four guestsFarmer began from the ground up.I always start with the rugs and build the spaces from there, she shares. And then we always do a combination of new and vintage pieces; sofas tend to be new elements, while accessories and things like side chairs are usually vintagethey wanted everything to be used in real life, not just feel like it.And now, thanks to Farmer, theres absolutely no question how her clients will while away many lazy days and nights on the lake. Take a look inside this pine-walled getaway.1Great RoomDavid MitchellThe design of the this room was based on the rug that Farmer custom designed. From there, she mixed modern pieces like the 1960s French Pierre Chapo leather chair with aesthetic movement stools and rustic pottery. The tufted sofa was custom designed by Farmers studio, the wall sconces were sourced through Jamb, and the Bogart cocktail table is from Shoppe Amber Interiors.2Great RoomDavid MitchellIts one long space bookended by two monumental stone fireplaces, explains Farmer of this cozy space. They actually picked the specific stones for each. The wrought-iron chandelier is from Formations.Advertisement - Continue Reading Below3Great RoomDavid MitchellTo the right of the fireplace is a rustic early-18th century open-front bookcase with Gothic reliefs. And the window seat is really long. They wanted places to read, relax, and curl up with a book and, of course, the lake is right outside the window, says Farmer,4Dining RoomDavid MitchellThe family opted for a less formal dining room that includes a custom table with room for 10 and a set of aesthetic-style chairs upholstered in Jennifer Shorto fabric. Again, Farmer designed the generous rug that grounds the space. I felt it was important that each piece had a beautiful hand to it, she adds. And that the materials imbued this idea of a simpler, somewhat disconnected lifestyle they have when theyre here.Advertisement - Continue Reading Below5Dining RoomDavid MitchellThe parchment and iron pendants are from Roman Thomas, and the leather console is from BDDW.6KitchenDavid MitchellIts a very functional kitchen, and they wanted it to feel approachable, so it has a lower ceiling than the rest of the space it opens to. The cabinetry around the sink has been painted in Studio Green by Farrow & Ball. The wall behind the sink is clad in Moroccan Zellige tile, and the handmade ceramic pendant lights are by Natalie Page.Advertisement - Continue Reading Below7StudyDavid MitchellIts a very cozy room, reminiscent of being on a boat, explains the designer. Its meant to feel enveloping and snugthe opposite effect you get from being in the great room. The sofa is by Dmitriy & Co., the chairs are from Nickey Kehoe in Los Angeles, and the Guillerme et Chambron cocktail table is from 1960. Overhead is a vintage midcentury Swedish pendant by Erik Hglund, and softening the floor is a vintage Moroccan rug.8Primary BedroomDavid MitchellFor the homeowners, this space is a retreat within a retreat that takes full advantage of the lake views no matter the season.

The shower and walls are clad in yellow Moroccan tiles. Jaspers Corsica wallpaper in dark saffron is a pleasant juxtaposition to the earthy tile. The pedestal sink is from Waterworks, and the Double Bubble light fixture is from Olampia in New York City.12Children's BedroomDavid MitchellIt isnt a huge spacenone of the bedrooms are overly large, shares Farmer. But all the childrens bedrooms have these Dutch doors to let air flow through and really encourage that indoor-outdoor feeling.

They really wanted to be able to have a lot of people sleep over, so we put in all these single wrought-iron beds and layered in vintage dressers. The beds are from Cottage Home Shoppe and the blankets are all from Pendleton. A combination of 19th- and 20th-century dressers dots the room, and for a bit of fun Farmer painted the floor in Farrow & Balls Indian Yellow. All the light fixtures are from Urban Archaeology.14PorchDavid MitchellThe epitome of indoor-outdoor living, this expansive porch is one of the familys favorite spaces all year long. The porch swing is identical to one the homeowners family had when she was young, so we custom built this one to look exactly like it as a nod to her vacations as a child. The lighting fixtures are from Urban Electric, and the mix of furnishings include pieces from Bielecky Brothers and Hollywood at Home.Advertisement - Continue Reading Below15The ViewDavid MitchellThe clients built their house on a 1.6-acre plot of lakeside land in New Hampshire.
