Custom Modular Homes In New Hampshire

Kill Mountain Building Co is the region’s approved manufacturer for PBS Modular Homes. This concept has been around for many years; however, recent innovation and quality have tremendously improved as of today.


Unmatched Strength

Prefabricated or Modular homes are manufactured with 1/3 more structural material for premium quality. This helps with the shipping, but more importantly, it also helps create a sturdy structure when put together!

Premium Quality Like No Other

Our building process produces consistent structure procedures, bringing about supreme quality. All of our homes are created in a quality-controlled environment, so when we assemble them, they are always double-checked for quality assurance.

Modular Construction Is Fast

Modular homes are built in 1/3rd of the time expected to develop a custom stick home. This is because they are built inside out of the weather and also because while the home is being manufactured in the plant, we start on your site work and foundation so that when the house is completed at the factory, we are ready for it to be shipped and craned onto the foundation.  This really helps with the short summer season in NH

10-20% Cost Reduction

Since modular homes are developed quicker and worked in a controlled environment, saving money is typical. Put that together with bulk ordering materials, and you could save on average 10 to 20 percent, contingent upon the size and plan of the structure.

Adaptability & Unique Design

Flexibility and complete customization are what we do best! With over 30+ years of experience and our creative thinking process, every home is unique and built the way that you want. Every new modular home is built with sturdiness, unwavering quality, and cost-efficiency in mind.

Unrivaled Products & Service

The modular home building process creates stable structures, bringing about unique quality. Top brand material, trim, and surfaces alongside 30+ years of skilled craftsmanship, guarantee that everything about your new venture lives up to your desires.

Quality Control Is Our Middle Name

We have strict quality control frameworks that comply with state regulations and guidelines. Quality control is performed at each phase of the development procedure to guarantee that every module is consistently up to code. Then, at last, a third-party seal of approval is stamped on each structure before leaving the manufacturing facility.

Excellent Service

Kill Mountain Building Co. has been building homes since 1988. Customer service is where Kill Mountain Building Co. prides itself the most. We walk you through the steps and make the process fun in a stressful time.

50% More Efficiency

Homes are 50% more energy efficient than the model energy codes. Energy codes are standards required by law. We go above and beyond to make sure that you do not only save money on your home when building it but save money for years to come.


Kill Mountain Builders stand behind their homes. Each home is back by a fantastic 10-year structural guarantee. This means that when we build something, it’s there to stay.
