In this bright and cheerful bunk room the bed takes center stage, with its frame featuring jumping porpoises. It was handcrafted from recycled lumber — by the same woodworker who made the bed in the master suite — and painted with low-VOC paint.

For the window covering, interior designer Linda Woodrum used eco-friendly fabric to create a tailored valence with oversized aqua and white checks. This same fabric was used for the curtain that hangs between the bedroom and the playroom.

The multipurpose cubby is the ideal spot for everything from studying to video games. Linda covered the cushy bean bags in outdoor fabric, which is durable, resists stains and can be removed for washing.

Two large windows bring in light, highlighting the room's green and aqua crayon colors. The windows are among the most efficient on the market. They reduce the amount of glare and heat gain through high-performance glass and are surrounded with additional flashing to help prevent moisture problems.
