Remodeling - January 1999 North Andover, Mass. The Internet is a driving force in the proliferation of home offices, so it is fitting that the owner of several important Internet businesses does much of his own work at home. Located in the dormered space above a three-car garage, this office incorporates high technology - ISDN Internet lines, an elaborate sound system, and computer-operated lighting - into a home-like environment with a spectacular view of the Merrimack Valley. Designed for the comfort of business visitors, the suite has its own full bath and private entrance. Part of a showcase whole-house remodel, the office was home to the owner and his family during the reconstruction of their living quarters. Location: North Andover, Mass. Designers: Joseph L. Luna, AIA and Luis F. Lobao, Luna Design Group, Lynnfield, Mass. General Contractor: Philip W. Lemire, Lemire Construction, Topsfield, Mass.
