The New Canaan Preservation Alliance launches its Spring 2010 lecture series with a presentation "New England Additive Architecture" by Mac Patterson, architect with Austin, Patterson Disston, based in Southport.

He will discuss how best to add to and renovate a historic residence, making the structure a viable one for 21st century living. As points of reference, he will present visuals of area projects, two in New Canaan.

The lecture will be held Sunday, March 28, at 4 p.m. in the Lamb room of the New Canaan Library. It is open to the public free of charge.

A graduate of Yale School of Architecture, in nearly three decades of professional practice, Patterson has renovated, restored, and expanded numerous historic properties.

His work ranges from the restoration of an 18th century house moved from Fairfield County to Kent and of a 19th century Federal house in Stonington, to a barn-like addition to a Victorian farmhouse in New Canaan, and the restoration and renovation of 12,000 square-foot. residence in Greenwich, returning it to its original Tudor style appearance. He has just disassembled, moved several feet to a new foundation, and reassembled a New Canaan barn.

Patterson's projects have been recognized with AIA/CT awards, and last year the Alliance presented an award to the owner of the New Canaan Victorian farmhouse he renovated and enlarged. He has served on the board of Connecticut's Antiquarian and Landmarks Society.

The alliance will host two more Sunday lectures in the Lamb Room, with the next scheduled for April 18, featuring David Scott Parker, architect, who will discuss his approach to restoring and renovating historic houses, townhouses and mansions. The final lecture takes place May 2; the speaker is to be announced. The Alliance is committed to keeping New Canaan a special place and has as its mission to establish as a community priority the conservation of the town's character-defining historic architectural and natural environments.

The program is not sponsored by the Library but solely by the Alliance.
