Drummond Designs is using new computer technology to simplify custom home plans. With its custom interactive rendering and design service, builders can customize any of Drummond's 1,000-plus stock plans and make changes via markups or a meeting with Drummond's design department. Once changes are established, a cost estimate is issued within 24 hours. After builders sign off on preliminary plans, the company says they can get blueprints and a material takeoff list in a couple of weeks. Visit www.drummonddesigns.com or call 800/567-5267.
