The BaseStation 900L is composed of two prefabricated modules:
– The Living Module: 37 feet long × 12 feet wide × 9.5 feet tall
– The TWO Bedroom Module: 37 feet long × 12 feet wide × 9.5 feet tall

Each module is delivered separately and installed on site to form a distinctive L-shaped layout. The overall footprint fits within a 49-by-37-foot square, creating a generous 37-by-25-foot courtyard space where the two modules frame an outdoor room.

This courtyard becomes a natural extension of the home—ideal for entry, gathering, gardening, or even parking. It’s one of the most compelling features of the 900L: a private exterior zone, architecturally defined, without increasing the unit’s square footage or cost.

At 880 square feet, the BaseStation 900L offers a spacious L-shaped layout with two bedrooms—one larger, one smaller—organized around a generous shared living space.

This model includes:
– An expanded L-shaped kitchen with 8' × 8' of counter space, room for a dishwasher, and a sink with backyard views
– A spacious full bathroom with a shower-tub combo
– A linen closet and stackable washer-dryer for everyday convenience

The 900L’s distinctive L-shape forms a 37' × 25' courtyard, naturally framed by the home itself. This outdoor room creates a meaningful extension of the interior—perfect for an entry garden, gathering space, or private retreat.

At just under 900 square feet, the 900L meets ADU requirements in cities like Burlington, Vermont, making it an ideal choice for infill housing, multi-unit development, or long-term living with room to breathe.

Comfort, Light, and Livability

The two-bedroom module offers a balanced mix of privacy and practicality. Thoughtfully designed to support a range of uses—sleep, work, guests, or growing families—each bedroom is filled with light and finished with care.

• Primary bedroom
  At 11'6" × 11', this spacious corner room easily fits a queen bed with additional room for nightstands, a dresser, or a desk.
  – Natural light: Two large windows plus a 30" × 72" casement egress window bring in generous daylight and fresh air
  – Storage: A 6' × 30" closet offers plenty of space for everyday essentials

• Secondary bedroom
  Slightly smaller (due to the circulation for the L) at 11'6" × 7'8" at its narrowest point, this room is well-suited for a twin bed, bunk beds, or a home office setup.
  – Natural light: One large window and a 30" × 72" casement egress window maintain brightness and code compliance
  – Storage: A 4' × 30" closet provides practical organization without sacrificing floor space

• Finishes and feel
  Both bedrooms feature durable Pergo-style flooring, recessed lighting, and a warm, modern aesthetic—creating simple, livable spaces that feel cozy without feeling small.

BaseStation’s exterior shell is engineered for resilience, precision, and long-term performance in the Northeast climate—ready for energy-conscious builds across Vermont and beyond.

Crafted for Durability, Aesthetics, and Sustainability

Wall and Ceiling Panels

Advantages Over Drywall
• Durability & Stability – Unlike drywall, Garnica plywood provides lateral stability and shear strength, eliminating cracks during transportation or installation
• Ease of Customization – ¾-inch plywood makes it easy to mount shelves, fixtures, and artwork without needing backing or blocking

Site Prep Recommendations

To ensure a smooth and secure installation, the following guidelines are recommended for the BaseStation 900L:

• 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 – 30 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.

Delivery & Installation

Delivery Logistics
The BaseStation 900L is delivered in two separate modules. We work with experienced rigging and crane partners to coordinate transport and placement of your unit. The open sides of each module are fully weather-wrapped for transport and protected during transit. Once on site, the modules are joined using structural GRK lag screws at designated connection points for a secure, permanent installation.

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. These costs vary based 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 confirm that access and install feasibility align with your site and budget. We begin with a virtual site visit. After a deposit is made, an optional in-person site visit can be scheduled, especially for more complex or nearby installations.

Timing & Insurance
Depending on distance and site complexity, delivery and crane work may take one or two days. In some cases, both modules can be placed in a single day.
The transport company provides insurance coverage during transit, and 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.
