Single deck capsule houses provide 150-250 sqft of living area on one level, while double deck models offer 280-450 sqft across two floors. The vertical expansion doubles usable space within the same ground footprint—a double deck capsule occupies the same land area but delivers twice the interior space. This vertical efficiency proves critical for properties with limited land area or seeking to maximize guest capacity.
Interior ceiling heights differ between configurations. Single deck units maintain 8.5-9.5 feet throughout, creating an open, spacious feel. Double deck models feature 7-7.5 feet on each level—adequate for comfortable movement but requiring thoughtful furniture selection. The lower ceiling becomes noticeable primarily in the sleeping loft, where guests spend most time resting rather than standing.
Cammi House single deck model comfortably accommodates 2 occupants with queen bed, seating area, kitchenette, and full bathroom. The double deck sleeps 4-6 people with separate sleeping loft, ground-floor living area, full kitchen, and bathroom. Resort operators report higher nightly rates for double deck units driven by family bookings versus couple-only occupancy in single deck models.
Single deck capsules use open-plan layouts maximizing the sense of space in compact footprints. The typical arrangement positions the bathroom at one end, kitchen/dining in the center, and sleeping/living area at the opposite end. This linear flow works well for couples but lacks privacy for families. Cammi House D7 model adds a sliding partition separating sleeping from living zones, providing basic privacy without permanent walls.
Double deck configurations separate sleeping and living functions vertically. Ground floors contain social spaces—kitchen, dining, bathroom, seating areas—while upper lofts serve as private bedrooms. This vertical zoning creates distinct day and night zones, allowing families to maintain different schedules without disturbing each other. The separation proves valuable for rental applications where guests appreciate bedroom privacy.
Stair design impacts usable space in double deck models. Cammi House uses space-efficient alternating tread stairs consuming minimal floor space versus standard stairs. Storage integrates into stair construction with pull-out drawers in each tread, recovering some lost square footage. The steeper angle may challenge elderly guests or young children—some properties prefer gentler stairs despite the floor space sacrifice.
Double deck capsule houses cost 30-45% more than single deck equivalents due to additional materials and complex assembly. Cammi House D5 single deck model retails at $28,000-32,000 while C7 Plus double deck prices at $45,000-52,000. However, the additional space makes double deck more cost-effective per usable square foot.
Structural requirements drive cost differences. Double deck units need reinforced floor joists supporting second-level loads, stronger staircases, and additional wind bracing resisting overturning moments on the taller structure. Steel framing weight increases 40-50% in double deck models, directly impacting material costs and shipping expenses—three single deck units fit per container versus two double deck units.
Installation labor costs rise for double deck capsules due to staircase installation, upper floor positioning, and safety considerations working at height. The additional assembly time addresses complexity but remains small compared to the space gained. Cammi House provides detailed assembly manuals for both configurations, with video tutorials reducing installation time for first-time builders.
Foundation requirements differ between configurations. Single deck units distribute weight across 6-8 foundation points, while double deck models require 10-12 foundation points with deeper embedment due to increased weight and height. A structural engineer's calculations ensure adequate bearing capacity, especially on soft soils.
Wind loading significantly affects double deck installations. The taller height presents more surface area to wind forces compared to single deck units. Cammi House double deck models include engineered tie-down systems rated for high winds, using helical anchors or buried deadman anchors depending on soil conditions. Coastal installations require enhanced anchoring to meet local building codes.
Crane requirements increase for double deck assembly. The upper floor section requires larger crane capacity versus single deck modules. Rural or difficult-access sites may face higher crane mobilization costs. Cammi House offers pre-assembled double deck delivery for accessible sites, eliminating on-site stacking but requiring larger crane capacity to place the complete unit.
Cammi House D5 single deck (180 sqft) remains the best-selling model for resort and glamping applications. The compact footprint, accessible price point, and 2-person capacity align with couple-focused markets. Standard features include queen bed, kitchenette, full bathroom, panoramic windows, and climate control. Over 800 D5 units operate across multiple countries since introduction.
D7 single deck (220 sqft) adds space for guests wanting more room without double deck complexity. The larger footprint accommodates a sofa bed, enabling occasional 3-person occupancy for families with one child. Interior upgrades include full-size refrigerator, two-burner cooktop, and expanded bathroom. Eco-resorts value the extra space for guests spending more time indoors during rainy seasons.
C7 Plus double deck (420 sqft) leads the family-sized category with sleeping capacity for 6 guests. The ground floor provides living/kitchen/bathroom space, while the loft contains two queen beds separated by privacy curtains. Resort operators report strong occupancy during peak season with premium nightly rates. The family-friendly design commands rate premiums over comparable single deck accommodations.
Q: Can I customize the interior layout of single or double deck capsules?
A: Yes. Cammi House offers semi-custom layouts within structural constraints. Single deck modifications include kitchen position, bathroom placement, bed orientation, and partition additions. Double deck customization addresses stair location, loft division, and ground floor configuration. Custom layouts add to base pricing and extend production time slightly. We provide 3D renderings before production, ensuring the layout meets your requirements.
Q: How do heating and cooling costs compare between configurations?
A: Double deck units consume 20-30% more energy due to increased volume and surface area. However, efficient insulation and HVAC systems minimize the difference—per-square-foot energy costs remain nearly identical. Cammi House includes energy calculations for your specific climate, helping operators budget utility expenses. Both configurations meet energy codes in all US states and can be optimized for various climates.
Q: Which configuration has better resale value?
A: Single deck units show stronger resale markets due to broader applications and easier relocation. However, double deck capsules generate higher rental income, potentially offsetting resale differences through superior cash flow. Market demand varies regionally—family-oriented destinations favor double deck, while romantic retreats prefer single deck. Cammi House maintains a network connecting sellers with qualified buyers for both configurations.
