Custom Modular Homes

Move Into Your 'Dream Home' In Just 12 Weeks For $250,000+ LESS

Modular construction delivers the same quality as stick-built homes while reducing overall costs by 20–30%.

We design, permit, deliver, assemble, and finish fully custom modular homes for South Shore families who want a beautiful, long-lasting home — faster and for significantly less than traditional stick-built construction. Modular projects built through Biviano General Contracting typically move from groundbreaking to keys in hand in 8–12 weeks, compared with 12–15+ months for typical stick builds, and often save families $200,000–$300,000 on comparable specs.

Why choose modular with Biviano GC?

Speed without compromise. Factory construction avoids weather delays and compresses build time dramatically, so families move in much sooner.

Real customization. You don’t get cookie-cutter boxes — you get fully custom layouts, finish selections, and premium options at a fraction of the design cost of stick-built homes.
Factory precision & durability. Indoor, climate-controlled assembly produces tighter seals, better structural consistency, and less material waste.
Single accountable GC. Mike Biviano and his team manage everything — design, permits, site prep, foundation, craning, assembly, finish work, inspections, and warranty service — so you have one point of contact and zero contractor drama.
Local expertise. As a lifelong Marshfield resident and long-time member of the town Planning Board, Mike knows local permitting, zoning, coastal requirements, and conservation issues — which keeps projects moving and avoids surprises.

Why Choose Modular Construction Over Traditional?

The number one reason is time and savings. Saving you 20-30% off what a traditional "Stick" build would cost you. We build a modular home for you in 8-12 weeks, depending on design and options, vs. 6-12 months for a traditional home. This ultimately means a lower cost for you. In addition, modular homes are built indoors in a climate-controlled environment where precision and quality control is much more significant. They typically cost 20-30% more than traditional homes (not including any additional savings because of the speed of construction).
