Carnegie is about to see the construction of its first green building.

Benjamin and Amy Bonham, of Moon, who own Bonham Asset Management LLC, want to build the Carnegie Town Lofts, an environmentally friendly and efficient nine-unit residence between Washington Gardens and the Governor's House on Washington Avenue.

Carnegie council gave unanimous site approval to the condominium development Sept. 10, following recommendation from the planning commission.

The contemporary building design will capitalize on natural light and feature tankless water heaters, two bedrooms, two bathrooms and two-car garages. Courtyard areas will offer privacy and doses of the outdoors.

The private road into the development will be maintained by the property owners. A homeowners' association will be developed.

Councilwoman Dorothy Kelly was pleased to note that the plans include specific names of plants. Mr. Bonham replied that architect Mark Fickley is also a landscape architect.

Each loft will sell for under $200,000, Mr. Bonham said, and mortgage holders can qualify for energy-efficient mortgages. In addition, each buyer will receive a $2,000 tax credit because of energy efficiency.

Mr. Bonham, who called Carnegie "a jewel in the rough," said he was drawn to the borough because of its pedestrian nature.

Within blocks of the lofts are restaurants, banks, entertainment, churches and public transportation, all an easy walk.

Construction is expected to begin by next month.
