Building Green Modular Homes

We build “green” into every custom modular home that is manufactured at our state of the art factory. Building Green begins in the design phase, continues through production with specific building techniques and culminates with finish items chosen by our customers such as appliances, fixtures, and design options.

Signature Building Systems homes are sold through our network of expert independent builders in CT, DE, MA, MD, ME, NH, NJ, NY, PA, RI, VA, & VT.

Custom Made Modular Homes

Signature Building Systems is a leading manufacturer of custom designed, pre-site built homes. The Pennsylvania based business has completed over 4,500 projects throughout the eastern seaboard – everything from ranches and capes to two-story homes and special, custom designed floor plans, as well as estate homes, multi-family residences, hotels, and even entire apartment complexes.

Whatever the project, Signature can work with the customer’s builder to get it done. The manufacturing process takes place at a state-of-the-art plant built with the sole intention of being a custom modular home manufacturing facility. How is this different to most our competition? Their facilities are converted from the old mobile home industry, rail car industry, or something similar to that. We were able to design our building with the sole intention of being a custom home manufacturer; as a result, we’re able to do some things differently. Our plant's entire structure was laid out with efficiency in mind, with each workstation carefully positioned to increase productivity. Our jigs, our mezzanines, our bridge cranes are positioned in such a way that they serve a number of departments, so we are able to move our material more efficiently.

Our Moosic, PA facility also features the modular industry’s latest, most advanced technology. Some of this special equipment allows Signature’s craftsmen to pre-fit sections, components, and even entire roofs before the structure is shipped to its destination. We will pitch the roof in our plant to make sure it fits. We will put the gable end panels in to make sure they fit and then we will disassemble them. This extra level of care ensures that the home will reassemble perfectly once it reaches the site. It also sets Signature apart from its competitors.

Every step of the manufacturing process takes place inside the plant’s controlled environment. The product is built in our facility from start to finish. This means that all materials, from lumber and sheet rock to insulation and shingles, are protected from the weather – and, the staff can work every single day in comfortable conditions, regardless of whether it is raining, snowing, freezing cold, or sweltering hot outside. Removing weather delays from the equation helps the team maintain a predictable, and relatively rapid, timeline. Typically, it only takes about eight days to build one module and the entire process – from hammering the first nail to turning over the keys – usually takes around 100 days.
