Housatonic Valley Association will hold its annual 27th annual auction to benefit the environment Dec. 3 at 1 p.m. in Washington.

Festivities will take place at Washington Primary School, 11 School St.

Auctioneer extraordinaire Tim Luke, who has been featured on HGTV’s “Cash in the Attic,” will take center stage at 2:30 p.m.

His co-auctioneer will be Greg Strahm.

Chris Zaima of Washington will showcase his design expertise for the event this year, along with Debby Bennett of Kent Greenhouse and Gardens.

The event will feature the auction, music by Miles of Swing, food by Executive Cuisine, cocktails and wine.

Honorary auction committee members at the diamond and platinum sponsorship level are invited to a special Bellini brunch reception hosted by Linda Allard and Baranski at Allard’s home from noon to 1 p.m. before the auction.

The auction is known for offering unique experiences such as exotic vacations, weekend country getaways, outdoor adventures, theater and sporting event tickets and fine dining. Items up for bid will include home furnishings, antiques, fashions, artwork, outdoor gear and more.

Reservations can be made by calling 860-672-6678 or online at www.hvatoday.org.

Proceeds from the event support HVA’s mission to conserve the natural character and environmental health of the communities of the Housatonic River watershed.

The auction has been a sold-out event for the past several years and raises more than $150,000 annually for projects that protect land, rivers and local drinking water. Last year it grossed $165,000. Donors, along with more than 225 guests, make this possible.
