If your building site is in New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, or eastern Pennsylvania, we will deliver and assemble a weathertight, prefabricated GO Home building shell, performance-tested and ready for interior and exterior finishes by your local general contractor. Like our Maine projects, yours will include:


• Our innovative, super-efficient Passive House design


• Fully detailed construction documents


• A factory-prefabricated, weather-tight building shell fitted with a high performance heat-recovery or energy-recovery ventilation system, assembled by the GO Home construction team and performance-tested on your site


In addition to the building shell, your GO Home package includes a full set of construction documents to guide you or your local general contractor in executing the site work, constructing the foundation, completing the insulation, installing the plumbing, mechanical, and electrical systems, and adding the interior and exterior finishes. Followed faithfully, these plans will yield the same result as if our own crew had built your GO Home.


1. Site 


The GO Home process begins with your individual house site, and assumes that you own the land where you plan to build and can provide a detailed site survey and photos of the site.

2. Plan, Product and Finish Selection


GO Home cuts through the complexity of building a new home by giving you choices of fully developed house plans that reflect our skilled architects’ best work. Our portfolio of designs ranges from a 600-square-foot cottage to three- and four-bedroom family homes up to 2,500 square-feet in size. All include the option of adding a garage or barn, and most adapt easily for one-floor living and universal accessibility. Several offer a choice of a traditional or contemporary façade.


After choosing a plan that meets your needs, consult our menu of products and finishes and download our Selections Form to complete the design in a way that expresses your own style. All of the available selections reflect our high functional and aesthetic standards. If you don’t find everything you’re looking for, we’ll work with you to identify alternatives (services provided on an hourly basis). If your needs call for a higher level of customization, we’ll refer you to our parent firm, GO Logic, for additions or alterations to one of our predesigned plans, or for a fully custom design.

3. Preliminary Cost Estimate 


Starting with the Base Price of the GO Home plan you’ve chosen and the options recorded on your Selections Form, we’ll factor in your site’s characteristics—as described in writing by you or your local civil engineer—to develop a preliminary cost estimate that covers planning, site work, production and delivery of a prefabricated building package, and on-site construction of the complete house. We will then review the estimate with you to ensure that the proposed project is a good fit for your budget and make adjustments if necessary. 


Construction costs vary widely from region to region, with prices outside of Maine generally higher than what we can build for here. Our preliminary estimate will reflect the prevailing local cost of custom construction, which we have found to be a reliable benchmark for the cost of building a GO Home in the same area.

4. Preconstruction Phase and Construction Documents 

Once you’ve approved the preliminary estimate, we will provide you with a proposal for the preconstruction phase, outlining all the stages of the planning and construction process and including a project cost estimate and schedule. (Separate construction contracts—one with GO Home and one with your local builder—will cover everything from groundbreaking to the completion of your house.)


When you sign the preconstruction phase contract and provide us with a retainer of $5,000, we will begin the process of adjusting your predesigned house plan to your site and producing the construction documents, which will describe in detail how it is to be built.


We will ask at this time that you retain, at your own cost, a civil engineer to draw the site plan and ensure that the new house complies with local zoning and setbacks, requirements for site access, stormwater management, wastewater management, and any other regulations that govern land use and site alterations. If your site does not have access to a public sewer, you will need to retain a civil engineer or septic system designer to design an on-site waste disposal system.


A GO Home architect will coordinate with the civil engineer to locate your house and any additional structures (for example, a garage or barn) on the site plan. We will then update the plans and 3D model of your predesigned house to reflect your product and finish selections and your site’s unique features, generating the construction documents the GO Home construction team and your local builder will use to price and assemble your house:


If you would like to make minor alterations to your house plan—for instance, changing a window or wall location—we will advise you on cost and feasibility. Because we strive for thoroughness and accuracy throughout the design process, the completed construction documents will provide all the detail necessary for GO Home and your local builder to generate fixed-price construction contracts.


5. Construction Pricing 


Because your project is outside of Maine, you will be responsible for retaining a local builder, with whom we will collaborate to ensure that your house is completed to our standards of construction quality and performance. GO Home will provide pricing for the construction and installation of the prefabricated building shell; your local builder, acting as the general contractor, will provide you with pricing for the site-built portions of the project. Taken together, these two elements will constitute the total construction cost for your house.


To ensure the most accurate pricing—and to expedite construction—all material, fixture, and finish selections should be finalized at this point. If any choice remains pending, we will apply a realistic allowance to account for the cost.

6. Financing


If you plan to finance your house, our construction documents and pricing will likely provide all the information your lender requires. For further details on construction financing, contact your local lending institution.

7. Construction Contract 


GO Home will provide a fixed-price contract that covers the complete cost of fabricating, shipping, and installing the panels that will make up the shell of your house. Your local builder will provide a separate construction contract with that will cover all of the on-site work that occurs before and after our installation of the panelized building shell. The type of contract and conditions will vary based on your builder’s standard documents.


Once you’ve signed a construction contract with GO Home and provided us with a down payment (typically equal to the cost of the foundation insulation plus 50 percent of the price of the window order), the project will proceed to permitting and construction. The remainder of the GO Home contract amount will be billed in two phases: when panels are ready for delivery (75 percent) and when panel installation is complete (25 percent).

8. Permitting 


GO Home will provide documents to support your application for all necessary building permits. If you would like us to handle the permitting process on your behalf, we will provide that service on an hourly basis.

9. Construction 


When all the necessary approvals have been obtained, construction begins!


The GO Home process is streamlined to make the most of factory panelization, with a construction schedule that hinges on two crucial elements: ordering the German-made windows we use for every project and prefabricating the building shell in our shop. Because the lead-time for windows is three months, we will finalize your window order immediately upon receiving a signed construction contract. Earthwork for the foundation will begin while the windows are being manufactured.


When the windows arrive at our factory and a GO Home crewmember confirms the finished foundation’s precise dimensions, we will begin fabrication of the building panels. After approximately four to six weeks, we will deliver the panels to your site by truck and spend the following two weeks assembling them on your foundation into an air-sealed building shell. The remainder of the construction process will be executed on site, by your general contractor.


GO Home will provide construction administration services for the duration of construction, as specified in the preconstruction phase contract, including answering contractor questions and reviewing shop drawings and submittals. Any design or customization services performed during the construction phase will be billed as additional services on a time-and-materials basis.

10. Completion


Nine months after you sign the construction contract—on a typical project—your home will be complete, performance-tested, and ready for move-in!
