Double Capsule House: Double Decker Designs, Drawings & Key Dimensions

The double capsule house reimagines compact living by doubling up on space—whether through side-by-side units or stacked double decker designs. Blending the efficiency of capsule homes with the versatility of multi-level living, these structures cater to small families, co-living setups, or anyone craving more room without sacrificing the iconic “capsule” aesthetic. Below, we’ll explore their unique designs, break down critical dimensions, and guide you through capsule house drawing resources to bring your vision to life.

What Is a Double Capsule House?

A double capsule house is a modular dwelling made by combining two capsule units, either horizontally (side-by-side) or vertically (as a double decker capsule house). Unlike single capsule homes (50–200 sq ft), these designs offer 200–500+ sq ft of functional space, with distinct zones for living, sleeping, and even work—all while retaining the signature traits of capsule living:

• Modular construction: Factory-built units that connect on-site in days, reducing construction time.
• Space efficiency: Multi-functional furniture, built-in storage, and smart layouts to maximize every inch.
• Durability: Steel or aluminum frames, insulated panels, and weatherproof exteriors (resistant to rain, wind, and pests).
• Privacy features: Drawing on Glamni’s sound insulation technology, mineral wool is used to fill the walls and seal joints, paired with adjustable smart glass (one click switch between transparent/frosted) to ensure privacy between upper and lower layers or adjacent units.

Double Decker Capsule House: Stacked for Style & Space

The double decker capsule house (vertical double design) is the most popular iteration, ideal for tight lots where horizontal space is limited. Here’s how it works:

Key Design Features

Layout:

• Ground floor: Open-concept living area with a kitchenette, dining nook, and bathroom—designed for daily activity and guest hosting.
• Upper floor: Private sleeping quarters (1–2 bedrooms) with lofted ceilings (up to 8ft) and small balconies (for fresh air and views).
• Connection: Space-saving access via a spiral staircase, foldable ladder, or compact straight stairs (built into the shared wall to save space).

Structural details:

• Reinforced steel brackets secure the upper capsule to the lower unit, with waterproof seals at the connection point to prevent leaks.
• The upper unit often features a sloped or curved roof (reducing wind resistance) and larger windows (strategically placed to avoid overheating).

Example models:

• Capsule Castle’s “Duo Loft”: A 350 sq ft double decker with a ground-floor workspace and upper bedroom, featuring built-in desks and a fold-out patio.
• Glamni’s “Stacked Pod”: Soundproofed double decker with smart locks and climate control, designed for urban co-living (two roommates, each with private upper/lower zones).

Capsule House Dimensions: Sizing Up Double Units

Precise capsule house dimensions are critical for ensuring functionality and compliance with local building codes. Here’s a breakdown for double capsule homes:

Single Capsule Unit (Base Dimensions)

• Standard size: 10ft (W) x 15ft (L) x 8.5ft (H) → 150 sq ft per unit.
• Interior space: Usable area ~130 sq ft (accounting for wall thickness and structural framing).

Double Decker Capsule House (Total Dimensions)

• Width: 10ft (same as single unit, saving lot space).
• Length: 15ft (matches the base unit).
• Total height: 17–18ft (8.5ft per floor + 1–2ft for roof/connection brackets).
• Interior height per floor: 7.5–8ft (enough for standing comfort, even with insulation).

Horizontal Double Capsule House (Side-by-Side)

• Width: 20ft (two 10ft units side-by-side).
• Length: 15ft.
• Height: 8.5ft.
• Total area: 300 sq ft (with 20–30 sq ft lost to shared wall/insulation).

Capsule House Drawing: Blueprints for Building

A detailed capsule house drawing is essential for DIY builds or working with contractors. These drawings include:

1. Key Drawing Types

• Floor plans: Top-down views of each level, showing furniture placement, door/window locations, and utility lines (electrical, plumbing).
• Elevation drawings: Side/front/back views with dimensions, roof angles, and exterior finishes (e.g., metal panels, wood cladding).
• Sectional drawings: Cross-sections revealing wall thickness, insulation layers, and staircase details (critical for double decker designs).
• Connection details: Close-ups of how two units join (brackets, seals, and structural supports).

2. Where to Find Capsule House Drawings

• Manufacturer-provided: Brands like Capsule Castle and Glamni include free basic drawings with unit purchases, tailored to their specific models.
• Design platforms: Etsy or eBay offer downloadable capsule house drawing sets ($50–$200) for standard double decker or side-by-side designs, with editable CAD files.
• Custom architects: For unique layouts (e.g., a double decker with a rooftop garden), hire a modular home specialist to adapt standard drawings to your needs ($500–$1,500).

Why Choose a Double Capsule House?

• Space vs. footprint: Double deckers fit 350+ sq ft into a 10ft x 15ft lot—ideal for urban or small rural lots.
• Flexibility: Start with one unit, then add a second later (most manufacturers design units to be expandable).
• Cost efficiency: A double capsule costs 30% less than a traditional small home of the same size (thanks to factory mass production).
• Style: Modern, futuristic aesthetics make them popular for rentals (Airbnb guests pay 20% more for unique double decker designs).

Tips for Planning Your Double Capsule House

1. Check local height limits: Double deckers (17–18ft tall) may exceed restrictions in some areas—verify with zoning offices first.
2. Prioritize insulation: In cold climates, ensure both floors have closed-cell foam insulation (R-value 6.5+) to avoid heat loss between levels.
3. Use drawings to plan utilities: Work with an electrician/plumber to map wiring and pipes using your capsule house drawing—critical for double deckers with upper-floor bathrooms.
4. Test furniture fit: Measure pieces (e.g., beds, couches) against interior dimensions to avoid overcrowding.

The double capsule house—whether as a stacked double decker or side-by-side unit—proves that compact living can be spacious, stylish, and functional.
