Space Haven Ship Layout Guide
Ship layout is the invisible factor that determines whether your crew thrives or barely survives. Two ships with identical systems and crew can have dramatically different performance based purely on room placement, corridor design, and adjacency bonuses. Poor layout adds minutes of walking time to every crew task, wastes power through inefficient node placement, and creates morale penalties when noisy machinery sits next to crew quarters. This guide covers the adjacency matrix for every room combination, optimal crew quarters designs scaled from early to late game, and the proven layout principles that experienced Space Haven builders swear by.
Room Placement Matrix — Adjacency Rules
Every room in Space Haven has optimal and suboptimal neighbors. Following these adjacency rules reduces crew travel time, minimizes power loss, and prevents chain reaction damage during combat. The matrix below covers the most common room pairings and whether they should be adjacent.
| Room A | Room B | Best Adjacent? | Why / Why Not |
|---|---|---|---|
| Oxygen Generator | CO2 Scrubber | Yes. These two systems form a life support pair. Keep them adjacent to minimize pipe routing and ensure CO2 removal operates at maximum efficiency. | Oxygen generators and CO2 scrubbers share the same sealed atmosphere requirements. Adjacent placement reduces the travel time for processed air, improving cycle efficiency by approximately 15%. |
| Power Generator | Crew Quarters | No. Power generators produce noise and heat that disrupt crew sleep quality. Crew sleeping in adjacent rooms suffer a -2 comfort penalty. | Always buffer power generators with a utility corridor or storage room. The noise debuff stacks with other negative comfort modifiers and causes crew morale to drop rapidly during extended travel. |
| Grow Beds | Food Dispenser | Yes. Crew must transport raw food from grow beds to kitchen. Adjacent placement minimizes travel time and keeps food spoilage low. | The food supply chain (grow beds, kitchen, dispenser) should form a continuous path. Break this chain and your crew wastes 2-3 hours per cycle on food logistics instead of productive work. |
| Water Purifier | Grow Beds | Yes. Grow beds consume water. Adjacent placement reduces pipe runs and simplifies water distribution planning. | Water is the heaviest resource to transport. Piping water across the entire ship creates pressure drop and increases the risk of a single hull breach cutting off your entire food supply. |
| Shield Generator | Bridge/Command Center | Yes, but separated by one room. The bridge is a critical system. Protect it with shield coverage but prevent direct adjacency to avoid chain damage. | Direct adjacency means a shield generator explosion damages the bridge in a chain reaction. A one-room buffer (corridor or storage) absorbs the blast while maintaining shield coverage. |
| Industry (Assembler, Ore Processor) | Storage Room | Yes. Industry rooms produce and consume materials constantly. Adjacent storage cuts hauling time by 50%. | Every square traveled by a crew member carrying materials is lost productivity time. A well-designed industry block has assembler adjacent to ore processor adjacent to raw material storage adjacent to finished goods storage. |
| Hyperdrive | Power Generator | Yes. Hyperdrives consume massive power during jump sequences. Direct adjacency ensures stable power delivery. | Power transmission loss increases with distance. A hyperdrive adjacent to its dedicated power generator receives 100% power efficiency. Separated by 3 or more rooms, efficiency drops to 85%. |
| Crew Quarters | Recreation Room | Yes, but with a door. Crew should flow naturally from quarters to recreation. Keeping them close encourages regular recreation use. | Crew members have limited free time between shifts. If the recreation room is far from quarters, crew will skip leisure activities, morale drops, and productivity suffers. |

Crew Quarters Design — Complete Size Guide
Crew quarters are your second largest space investment after industry, and getting the size right dramatically impacts both ship efficiency and crew morale.
| Quarters Size | Settlers Housed | Comfort Bonus | Space Efficiency |
|---|---|---|---|
| 2x2 (Minimum Survival) | 1 | +0 Comfort | High density but zero comfort. Crew housed in 2x2 rooms suffer permanent -3 morale penalty. |
| 3x3 (Basic Quarters) | 1 | +2 Comfort | Standard early-game quarters. Provides basic comfort without excessive space consumption. Good for the first 10-15 crew members. |
| 4x4 (Comfortable Quarters) | 1 | +5 Comfort | Mid-game standard. Includes space for a personal storage locker and decorative item. Worth the space investment once crew morale becomes a limiting factor. |
| 4x6 (Double Bunk) | 2 | +3 Comfort per settler | Best space-per-settler ratio. Houses two crew in shared quarters with acceptable comfort. Optimal for large crews of 20+ where individual 4x4 rooms become unsustainable. |
| 5x5 (Luxury Quarters) | 1 | +8 Comfort | Low efficiency but maximum morale benefit. Reserved for high-skill crew whose productivity you cannot afford to lose. One luxury quarter captain can offset morale penalties for the entire ship. |
| 6x6 (Captain's Suite) | 1 | +12 Comfort, +5% Crew Productivity | Only for the ship captain. The productivity bonus applies to all assigned duties. Not worth building more than one per ship. |
The Three-Zone Layout Principle
Successful Space Haven ships organize their interior into three distinct zones: the Industrial Core, the Crew Habitation Ring, and the Outer Systems Belt. Each zone has distinct adjacency requirements and power needs.
The Industrial Core sits in the center of your ship and contains assemblers, ore processors, and raw material storage. This zone needs maximum power and generates the most heat. It should be surrounded by a utility corridor that acts as a heat buffer and provides redundant power routing. Never place living quarters adjacent to the Industrial Core; the noise and heat penalties will cripple your crew's morale.
The Crew Habitation Ring surrounds the Industrial Core and contains quarters, recreation, food systems, and medical bays. This zone prioritizes comfort and travel efficiency. Design it as a continuous loop so crew members can reach any habitation room without backtracking. The food supply chain (grow beds, kitchen, dispenser, dining area) should form a straight path through the center of this zone.
The Outer Systems Belt sits along the hull edges and contains shield generators, weapon hardpoints, hyperdrive, and redundant life support. These systems are most critical during combat and least accessed during normal operations. Their perimeter placement gives them maximum shield coverage and isolates combat damage from the habitation zone.
Corridor Design and Traffic Flow
Corridors are the most overlooked aspect of ship design but have the biggest impact on crew productivity. A well-designed corridor network reduces average crew walking time by 25-40 percent compared to a haphazard layout. The golden rule is: never make a crew member walk through one room to reach another unless the intermediate room is part of their task.
One-tile corridors are acceptable for secondary access routes but create traffic jams when two crew members try to pass. Two-tile corridors should be the standard for main routes through your ship. Three-tile corridors are luxurious but only necessary for the main artery connecting the Industrial Core to the Crew Habitation Ring.
Place power nodes along corridors, not inside rooms. This lets you redistribute power without deconstructing room walls and ensures a single room hit does not knock out power to its neighbors. Each corridor junction should have at least one power node. If a junction loses power, you lose all connected routes.
Frequently Asked Questions
Q: What is the most efficient shape for a ship hull?
Rectangle is optimal for most ship designs. Square ships minimize exterior wall tiles for a given interior area, which reduces hull block cost. Long narrow ships have more wall per interior tile but are better for combat because incoming fire is spread along the long axis. The consensus among experienced players is: early-game ships should be compact squares (12x12 to 16x16 tiles), mid-game ships should be rectangles (14x20), and late-game ships can be any shape that fits your three-zone layout.
Q: How do I prevent crew from sleeping through their shifts?
This is almost always a travel distance problem. Your crew is waking up too far from their work stations and using their entire free period just to commute. Shorten the distance between crew quarters and work areas. A well-rested crew member with a 5-tile commute works 30 percent more efficiently than one with a 25-tile commute. Also check your schedule settings: the default 8-hour sleep schedule often is not enough if commute times are long. Set 9 or 10 hours of sleep for crews with long commutes.
Q: Should I build one large ship or multiple smaller ships?
Multiple specialized ships outperform one large generalist ship. A dedicated industry ship, a dedicated agricultural ship, and a dedicated combat ship can each be optimized for their specific task without making compromises. One large ship becomes a single point of failure: lose it in combat and your entire run ends. Fleet composition of 3-5 ships with overlapping capabilities provides redundancy. If your industry ship goes down, the agricultural ship can produce basic materials until you rebuild.
