Why Modular With Biviano

Same Quality. Same Codes.
Half the Time. A Fraction of the Stress.

It's not cutting corners — it's The 12-Week Dream Home System: your home is built in a climate-controlled factory at the same time we prep your site and pull permits.

01
20–25% Less

Than stick-built — roughly $300/sq ft vs. $400–$600/sq ft. Most families save $200K–$300K.

02
8–12 Weeks

Not the 12–15 months a traditional custom build takes. Move in while neighbors are still framing.

03
No Weather Delays

The factory build and your site prep run simultaneously — rain and snow never stall the schedule.

04
One GC, Start to Finish

Design, permits, foundation, factory build, crane, finish work, inspection — Mike handles all of it.

"But isn't modular a trailer?" No. These look identical to custom stick-built homes — built to the same codes, set on a permanent foundation, and they appraise and finance identically. You won't be able to tell the difference. Neither will the appraiser.

Straight Answers

Your Questions, Answered.

Yes — and then some. Modular homes are built to the exact same Massachusetts building codes as stick-built, on permanent foundations, with the same architectural details and finishes. Because they're assembled in a climate-controlled factory (no rain on the lumber, no rushed crews), the build is often tighter than site-built. Once finished, they're completely indistinguishable from any custom home on the street.
Absolutely. You use a standard construction loan from the same local South Shore banks you'd use for any custom home — same process, same terms. On a permanent foundation, a modular home appraises identically to stick-built, so financing and resale work exactly the way you'd expect.
It is, because two things happen at once. While your modules are being precision-built in the factory, we're simultaneously prepping your site, pouring the foundation, and pulling permits. Traditional construction does all of that in sequence — one delay after another — which is why it stretches to 12–15 months. The parallel build is the whole secret.
Roughly $300/sq ft all-in — so a 2,500 sq ft custom home lands around $625K, versus $1M–$1.5M for the same home stick-built. Your free consultation includes a personalized Cost Breakdown Report with your exact number, based on your land, your layout, and your finishes. No guessing, no surprises.
