Everything owners and operators usually ask about Vessel Calypso, from specifications and pricing to sites, timelines and support.

About Vessel

What is Vessel?

Vessel designs, manufactures and distributes multifamily buildings that lower construction and operating costs and reduce construction and lifecycle risk, with sustainable, healthy, energy-efficient, technology-enhanced homes. Vessel Calypso is its first product.

What is Vessel Calypso?

Vessel's midrise multifamily building system. Factory-made panels with a steel structural system ship flat and are assembled on site into a complete, ready-to-occupy building. Homes have nine-foot ceilings, floor-to-ceiling windows, a full kitchen, a private dressing room and an oversized rain shower. Buildings are 100% electric, solar-compatible and run on Vessel Intelligence.

Who is Vessel Calypso designed for?

Market rate, workforce, student, senior and affordable or income-restricted housing, for landowners who want to create or operate multifamily housing on their land.

What are the unique advantages of a Vessel Calypso?

Residents get 9' ceilings, abundant daylight, luxury finishes, in-unit laundry and all-electric, net-zero-ready homes with remote control of HVAC, speakers and lighting. Owners get fixed per-unit pricing, no change orders, buildings in as little as six months, lower construction interest, faster lease-up and lower operating costs, so parcels as small as 0.5 acres work.

How is Vessel Calypso different from modular construction?

Modular describes a method. Vessel Calypso is a panelized product, not a volumetric system, so Vessel can invest heavily in R&D and prototyping for predictable, high-quality results. Flat, stacked panels cut shipping costs and allow standard on-site inspections.

What is Vessel's track record?

2 buildings (100 units) complete in the Northeast, 4 buildings (278 units) under construction and a pipeline of about 1,600 units, mostly in the Northeast and Florida. The oldest has operated for 3+ years with strong retention and renewals.

Specifications

What is included in the Vessel Calypso building system?

The complete vertical build, manufactured and installed by Vessel and delivered ready for occupancy. It covers the steel structure, interior and exterior walls, cabinetry, full fit-out, elevators, stairwells, sprinklers, HVAC, plumbing, electrical, lighting and building controls.

What building heights and configurations are available?

3, 4 or 5 stories, at grade or on a podium or structured parking (up to 5 residential stories above). Depths of 90', 82' or 74', widths from 56' to 154', and multiple buildings per property.

What unit types and sizes are available?

One-bedroom minis, Vessel's studio (~480 sf), one-bedrooms (~560 sf) and a standard two-bedroom (~960 sf) in every configuration. Combining units creates more two- and three-bedrooms (~960 to 1,120 sf). The standard layout is mostly ones and minis with one two-bedroom line from the 2nd floor up.

What materials are used inside the units?

High-pressure laminate walls that are durable, non-combustible, antimicrobial and hypoallergenic, and non-combustible, fabric-like stretch ceilings. Damaged finishes are replaced individually and inexpensively.

What is the building's energy performance?

The envelope exceeds current code with triple-glazed, low-E, argon-filled windows and roughly R-21 continuous insulation. 100% electric, solar-compatible and designed to meet or exceed programs such as Energy Star.

How is sound isolated between units?

Wall and floor assemblies are engineered and tested to exceed STC 55 and IIC 55 in both directions.

How are HVAC, electrical, and plumbing systems installed?

In engineered chase ways behind removable panels, so routine maintenance does not require opening walls. Roof-mounted units provide multi-zone heating and cooling that residents control individually and remotely.

Buying a Vessel Calypso

What does the process look like, from first conversation to move-in?

You pick a site and Vessel returns a feasibility study and proposal. You lead entitlement while Vessel attends meetings and supplies presentations, renderings and plans. You sign a fixed-price contract and Vessel files building permits. Your contractors do the horizontal work (demolition, excavation, grading, below-grade utilities, stormwater and the foundation to Vessel's specs) and an as-built survey. Vessel then builds and delivers with a Certificate of Occupancy.

Do I need to bring my own site?

In most cases, yes. In select markets Vessel may help find a site or offer one already entitled. Vessel can run a quick feasibility and massing study on any site you are considering.

Do I need to hire my own general contractor?

No. Vessel is responsible for all building construction. You only retain contractors for horizontal work.

Do I need to bring my own architect or design team?

No. The building is pre-engineered. Vessel identifies the local Architect of Record and provides MEP-S drawings and engineering calculations. You need a civil engineer and any consultants your approvals require.

What am I responsible for versus what does Vessel provide?

You handle site acquisition, entitlement (with Vessel's support) and horizontal construction, including foundations with utilities stubbed. Vessel erects and completes the building through Certificate of Occupancy.

Can I tour a completed Vessel Calypso building before I commit?

Yes. Completed buildings in the Northeast are open for tours, with more as new markets complete.

Who builds and operates it

Who manufactures the Vessel Calypso system?

Vessel, in its own factory, using just-in-time production. Flat-packed panels ship to the site for a Vessel affiliate to install.

Who installs the building on site?

Vessel, working with subcontractors that may include general contractors, construction management firms and factory-authorized installers.

What kind of labor is required to install it?

Standard electricians and plumbers. Components connect like a pre-designed kit, so no specialized modular labor is required.

Who is responsible for the foundation?

You, the owner, built to Vessel's specifications with utilities stubbed. Vessel then executes the vertical construction.

Does Vessel operate the buildings itself?

No. Vessel designs, manufactures and installs the building system. Owners and operators run it day to day.

Pricing and financing

How much does a Vessel Calypso building cost?

Vessel prices each building as an all-in, blended per-unit figure from foundation to Certificate of Occupancy, fixed in your contract. It depends on your site, market and layout, so talk to us for a figure on your project.

What's included in the price?

Zoning materials with drawings and renderings, attendance at pre-application and application meetings and hearings, permit-level plans and specifications, the installed building with a Certificate of Occupancy, post-construction training and marketing materials. No change orders once signed.

What's not included, and what am I responsible for?

Site acquisition, entitlement and horizontal construction (site work, landscaping and the foundation). Vessel supports the approval process.

Is there a deposit, and how does payment work?

Small fees cover Vessel's zoning participation and permit-level plans. About 50% of project cost is billed on signing the fixed-price contract to fund materials, with the rest tied to production and installation milestones. Detail is in the proposal.

How does Vessel Calypso pricing compare to conventional construction?

Typically 10% to 30% below conventional construction depending on market, with lower design fees and construction interest. Lower operating expenses cut total cost of ownership and improve achievable NOI.

What financing options are available?

Conventional financing from any lender you choose. Vessel can introduce lenders who know its product, including those that have placed permanent Agency financing on Vessel projects.

Site and permitting

What kind of site does Vessel Calypso work best on?

Square or rectangular sites work best, and irregular sites often work with an adjusted orientation or several smaller buildings. Vessel Calypso suits smaller infill parcels that conventional multifamily cannot build on cost-effectively.

Is there a minimum or ideal project size?

Buildings range from 30 to 100 units. Savings are greatest on smaller sites of 48 to 72 units, though larger sites in high-cost markets also benefit. Vessel can assess your site and send a proposal.

How does zoning and entitlement work?

The owner leads entitlement. Vessel supplies materials, standard architectural and permitting documents and evidence of code compliance. Timelines vary by jurisdiction, so check with your local attorney and consultants.

Does Vessel Calypso meet local building codes?

Yes. It is designed to meet or exceed codes nationally, including IBC provisions such as open-ended corridors, and Vessel pursues state-specific approvals as it enters new markets.

Can Vessel Calypso handle coastal or hurricane-prone sites?

Yes. Exterior materials are tested for coastal and salt-air exposure, steel is galvanized, and hurricane-rated windows and components are used where required.

Can Vessel Calypso accommodate sloped or irregular topography?

Yes. A podium allows tuck-under or full parking beneath the building and accommodates some grade change.

Delivery and timeline

How long does construction take?

Roughly 6 months once the foundation is complete and utilities are stubbed.

How long does the whole process take, from signing to move-in?

Entitlement and permitting are the biggest variable. Once construction starts, expect 9 to 11 months in total depending on horizontal work, including about 6 months of vertical construction.

How does Vessel keep the schedule predictable?

Fixed-price, no-change-order contracts and factory-built components remove the variables that usually cause delays and overruns.

Can I visit a building while it's under construction?

Yes. Vessel brings prospective partners through active sites, typically during building windows.

What happens once construction is complete?

Vessel supports final inspections, delivers the Certificate of Occupancy and a move-in-ready building, trains your maintenance and management team and hands over materials for your marketing.

Warranty and support

What warranty does Vessel provide?

A limited 10-year warranty covering parts and services, detailed in the standard contract.

How easy is it to maintain and repair the building?

Very easy, which materially lowers operating costs. MEP is reached behind removable panels without opening walls, and two-sided finish panels can be replaced individually.

What happens if a wall panel or finish gets damaged?

Order the individual replacement part rather than rebuilding the wall. In practice, buildings have seen very little damage.

What security and technology features are built in?

A property-wide camera system and Vessel Intelligence building controls, with APIs to integrate an operator's existing security systems.

Who do I contact for support after move-in?

Vessel, which supports operators on warranty items, replacement parts and system questions after delivery.

Customization

Can I customize the unit mix?

Yes, within the standardized building shape. Choose the mix of minis, one-, two- and three-bedrooms, plus the building's height, width and color.

Can units be repurposed for amenities like a gym, community room, or shared laundry?

Yes. Any unit can become shared amenity space, and adjacent units can combine into a larger space such as a fitness room.

Can Vessel Calypso accommodate a pool or other site amenities?

Yes. Your site can include any amenities your market calls for.

Can Vessel Calypso meet full ADA accessibility requirements?

Yes. The design can accommodate ADA accessibility for 100% of units.

Can the system be adapted for senior housing or other specialized populations?

Yes. Options include a wider bathroom turning radius, roll-under sinks, shower seating and shared common spaces. Fully enclosed, climate-controlled hallways are in development.
