About this House

Old North Boulder Family Home on Nearly Acre

5 Bedrooms + Flexible Living Space | 2 Full Baths | Large Private Yard | Pet Considered
$4,950/month | Available September 1 | 12-month lease preferred

Recently updated brick ranch in a quiet, established North Boulder neighborhood, set on nearly one-third of an acre with mature trees, privacy and an unusually generous amount of outdoor space.

The home offers a flexible five-bedroom layout, two full bathrooms and two separate living areas, making it particularly well suited to a family or professional household looking for room to live, work and relax.

The location is one of the home's greatest advantages. The house is just half a block from Columbine Elementary and within easy walking and biking distance of Ideal Market, other grocery stores, tennis and racquetball courts, the North Boulder Recreation Center, fitness and yoga studios, trails, cycling routes and downtown Boulder. It's close to everything while still feeling peaceful and residential.

The Home:

The main level includes three bedrooms, a full bathroom, kitchen, dining area and comfortable living room.

The fully finished and renovated lower level provides two additional spacious rooms, a second full bathroom, laundry room and a separate TV/family room. The flexible layout works well for children, guests, a home office or additional living space.

The kitchen looks onto the outdoor space and opens through French doors to the deck and yard, creating an easy connection between the indoor and outdoor areas.

The mature trees provide shade, privacy and a lovely established setting. The generous lot offers plenty of room for children, pets, gardening and outdoor activities. During the winter months, when the trees are less dense, the Flatirons can be seen from the property.
