ALAMO, California (AP) -- Billionaire and former PeopleSoft Inc. owner David Duffield plans to revise blueprints to build a mansion larger than the Hearst Castle after neighbors complained the hotel-sized home was out of character with the area.Duffield, the founder of the software company, released blueprints last month for the proposed 72,000-square-foot house in Alamo, California, a suburb east of San Francisco. It would have been bigger than Microsoft chairman Bill Gates' mansion and the White House.Initial plans for the 22-acre lot called for a horse stable, two swimming pools and a 20-car garage.Neighbors in the Bryan Ranch Homeowners Association complained the mansion would detract from the natural beauty and privacy of the subdivision. More than 230 homeowners signed a petition opposing it."We have been listening to the concerns of several neighbors and members of the community and are proposing to modify/amend some of the conceptual architectural plans submitted," Jim Dugdale, Duffield's project manager, wrote in an e-mail to the association.Duffield's spokesman did not immediately return a call seeking comment, and the e-mail did not say what the changes would be.Duffield made most of his $1.1 billion fortune by reluctantly selling PeopleSoft to Oracle Corp. last year.Copyright 2005 The Associated Press.
