Dozens of volunteers are spending their weekend constructing a small, but worthwhile building in a Mott Haven garden.

The effort is part of the New York Restoration Project at the Willis Avenue Community Garden.

The volunteers are building what they call a "Garden Casita," or little house in Spanish.

Once completed, the building will be used to host several activities, such as cooking, domino playing, shelter from the rain and performances. Also, an outdoor kitchen will be built on the roof, along with solar panels to gather energy.

The Garden Casita is now open for the public to enjoy. An official grand opening is scheduled for this fall.
