The builder, Haven Custom Sentry Box, based in Selinsgrove, Pa., shipped the house to Massachusetts in sections that have been assembled over the past few months on a 21,000-square-foot lot.
“Twenty-five years ago, they tended to be smaller box homes — ranches, split levels,” said Mark Leff, senior vice president of Salem Five bank and former president of the Home Builders Association of Massachusetts. “You were limited to Formica counters and linoleum flooring. Their image was a step up from the doublewide [trailer]. Today, we see some multimillion dollar homes built with modular construction.”
Francine Townsend, cofounder and principal of Marshfield-based Sandcastle Group, the general contractor for the Poiriers’ home, said her company plans to put together another modular home in Wellesley that will cost about $3 million.
“Over the last 10 years our business has evolved to the higher end,” said David Mertz, vice president of sales for the modular home builder Simplex Homes, of Scranton, Pa. “Our designs have gotten a lot more elaborate — better windows, better cabinetry, and energy-saving measures.”
Those upgrades also put such homes out of the reach of many buyers.
Overall, manufactured houses in the United States remain cheaper than site-built ones. According to the National Association of Home Builders, the average price of a manufactured home in 2010 was $138,126, compared with $204,553 for a house built the traditional way.
Less-expensive Prefab House tend to be those built with a basic design and few modifications, said Townsend, whose company handles both the high and low ends of the market. “The people who keep it the simplest get the most savings,” she said.
