Base Station 688T

Tuned for Living. Trim in Size. Totally Versatile.

The BaseStation 688T builds on the foundation of the 400, expanding its capability with the addition of two integrated modules—a mudroom airlock entry and a flexible second bedroom—all within a highly efficient, compact footprint. With approximately 688 square feet of living space, the 600T functions beautifully as a two-bedroom primary residence, ADU, guest house, or small family home. Its clean, modern layout and modular precision make it one of the most space-smart homes in the Satellite series.

At the core is the BaseStation 480 module, featuring a bright, open living area, functional kitchen, full bathroom, and private bedroom. To that, the 600T adds a mudroom airlock with dual entry doors, offering both a welcoming front entrance and a potential back door that connects to a deck or garden. This entry space improves energy performance while creating room for storage, boots, coats, and daily transitions in and out of the home.

Connected on the opposite side is a Task Module, configured as a second bedroom but designed to support a wide range of uses—from guest space to home office, library, or studio. With all plumbing and core systems located under the 480, the 688T maintains the same energy efficiency and mechanical simplicity as its smaller sibling.

Step into the BaseStation 688T, and you’ll experience the same open feeling and calming flow found in the 480—with just the right amount of expansion. The living space and kitchen feel airy and connected, and large windows provide natural light and views throughout the home. The added bedroom or task room provides just enough separation for privacy or focused work, while the entry module offers a sense of threshold, protection, and practicality.

Whether you’re creating a versatile two-bedroom home, expanding your rental potential, or simply looking for a more livable compact layout, the 688T delivers an elegant balance of form, function, and adaptability. With its small footprint, smart use of modular components, and sleek exterior, the 600T offers more than space—it offers possibilities.

Compact Footprint, Expanded Possibility
Efficient, Adaptable, and Designed for Daily Life

The BaseStation 688T is a 688-square-foot, two-bedroom modular home built from three integrated modules—a living core, a mudroom airlock entry, and a flexible task space. This configuration offers a sleek and highly functional layout ideal for full-time living, small families, guest housing, or modern downsizing.

Its clean lines, compact footprint, and modular clarity give it a distinct architectural presence while keeping installation and utility costs low.

Inside, the home builds on the foundation of the BaseStation 480, adding:

  • A mudroom airlock with dual entry doors for energy efficiency, storage, and seamless indoor-outdoor flow

  • A second bedroom or task room, ideal for guests, work, reading, or quiet retreat

  • The same efficient kitchen, bathroom, and living space layout as the 480, with no compromise on quality or comfort

With a refined exterior, flexible interior, and smart modular sequencing, the 688T brings together simplicity and versatility—creating a right-sized home that lives well beyond its square footage.

  • Site Prep Recommendations

    To ensure a smooth and secure installation, the following guidelines are recommended for the BaseStation 600T:

    • Foundation Type – Can be installed on either precast concrete piers, helical piers, or a standard full foundation, depending on site conditions and project goals.

    • Recommended Support – 22 piers total for pier-based installations.

    • Elevation – Unit should be set a minimum of 24 inches off the ground to allow proper access for utility connections and airflow.

    • Insulated Crawl Space – For pier installations, we recommend creating an insulated and heated crawl space beneath the utility portion of the modules. Waste plumbing is connected underneath and must remain protected from freezing.

    • Stone Pad – A 4–6 inch crushed stone pad should be laid beneath and around the perimeter of the unit to ensure drainage and long-term stability.

    • Site Work Responsibility – All site work, including foundation, excavation, utilities, and permitting, is the responsibility of the client and their general contractor.
    Up End This does not provide site services directly but will coordinate closely with your GC, offering all necessary specs and support to ensure a successful install.

  • Delivery & Installation

    Delivery Logistics
    The BaseStation 600T is delivered in three modules: the main living unit (identical to the BaseStation 400), a mudroom airlock, and a Task Module used as a second bedroom or flex space. We work with trusted rigging and crane partners to coordinate transport and placement on site.

    Once delivered, the modules are joined on site using structural GRK lag screws, creating a seamless and secure connection between each component.

    Delivery Costs
    The cost of transport and crane services is not included in the base unit price and is paid directly by the customer to the rigging and crane providers. Pricing depends on distance from Johnson, Vermont, site access, and crane capacity.

    Up End This will coordinate with your general contractor and the rigging/crane team to ensure a smooth delivery. We are on site during the entire install process, and that time is included in the base unit price.

    Up End This charges only for mileage based on delivery distance. No additional labor or coordination fees are added at this time.

    Site Review Process
    Delivery planning is discussed early in the design process to assess access and ensure the site can accommodate crane placement and module delivery. We begin with a virtual site visit. After a deposit is made, an optional in-person site visit can be scheduled, especially for nearby or more complex sites.

    Timing & Insurance
    Delivery and crane work typically take one to two days, depending on distance and site conditions. All modules may be installed in a single day when feasible. The transport company insures the unit during transit, and all road permits are managed and billed directly by them.

  • Optional Upgrades for Exterior Finish
    Roof and siding options are not included in the base module price and are offered as customizable upgrades. Pricing for these options is currently in development and can be discussed as part of the purchasing process.

    Buyers always have the option to install their own roof and siding systems on-site, using the prepped and fully sheathed base modules as a starting point. For those who prefer a streamlined approach, we offer high-performance exterior solutions built for Vermont’s climate.

    Roof Options
    Two primary roof configurations are available: a Shed Roof and a Gable Roof, both designed to work seamlessly with the BaseStation system.

    Roof structures are constructed using a hybrid approach—key components are fabricated in the shop and delivered to the site, where the roof is assembled in one to two days, depending on module size.

    Each roof includes:
    • R-67 insulation total (R-45 in the structural deck plus R-23 installed on site)
    • ZIP System roof sheathing with sealed, taped seams
    • Corrugated metal roofing with matching trim and drip edge

    These roof systems are engineered for thermal performance, speed of install, and long-term durability in all seasons.

    Siding System
    Our siding upgrade begins with 1.5-inch Rockwool Comfortboard applied around the full envelope for continuous exterior insulation. A ventilated rainscreen system is installed over the insulation, creating space for the siding material to dry and breathe.

    The standard siding material is ¾-inch Garnica DuraPly, a high-performance plywood panel built for exterior use. Manufactured from sustainably harvested European poplar and bonded with weather-resistant resins, DuraPly offers:
    • Dimensional stability and high impact resistance
    • Weather, fungus, and insect durability
    • Low weight for easier handling
    • Toxin-free construction with no added formaldehyde

    Each panel is:
    • Edge-sealed with marine-grade epoxy
    • Coated in a high-grade exterior enamel paint
    • Offered in a range of colors
    • Rated for 30-year exterior performance

    Together, this siding system creates a clean, modern look while delivering energy efficiency, moisture resilience, and low maintenance for years to come.
