Houzz Tour: Sophisticated Family-Friendly Flat

"My client's favorite color was gray, and she brought me the issue of Domino featuring Jenna Lyons' townhouse as her inspiration because she loved the way they used lots of gray with those pops of yellow," says Davin. This soft color palette carries through all of the open space and keeps the dining and living areas sophisticated, light and cheerful.

The dining room incorporates an interesting and versatile mix of materials, textures and eras; it includes a custom-made dining settee, reupholstered chairs from the 1950s, a wood and metal table and a barn light. The result is a comfortable, beautiful and functional space.

A comfortable sectional sofa holds a mix of muted yellow pillows. A leather ottoman can be used as a coffee table or extra seating. The painting, by artist Nancy Christensen of Charleston, South Carolina (a friend of the client), picks up the lavender color of the Scottish throw.

This office was designed with a potential future transformation in mind. The gray walls and vibrant blue window treatments could be incorporated into a nursery, and the Parsons desk could take on many functions in just about any room.

When their second child came along, it was easy to transform the office into a nursery, swapping out the desk for a crib and the Keep Calm and Carry On posters for flags with the letters of the baby's name. Pops of pink were added to the gray, blue and white color scheme.

The couple used this room as a nursery (as shown) when they first moved in. Now that their son is older, they've swapped the crib for a twin bed, a very easy transformation from baby to bigger boy bedroom.

Future transitions drove the design of the master bedroom as well. "My client knew that this furniture would be for the guest room in their next home, so we stuck with calm, gray and gender neutral," Davin explains. "She also wanted a bed that resembled Cameron Diaz's character's bed in the movie The Holiday."

The wallpaper has a fun Art Deco floral print that does not overwhelm the room. Swing-arm reading lamps make it possible to place a tufted occasional chair where a nightstand would traditionally go. Like the rest of the home's furnishings, those in the master bedroom work well for this stage of the family's life and will continue to do so in the next.
