Two connected spheres give you a building. Three or more give you a campus.
The jump from a duo to a cluster is not just additive. When you introduce a third sphere, you unlock layout geometry that two spheres cannot produce. Branching paths. Central hubs. Dedicated circulation. The difference between a hallway and a floor plan.
The Geometry of Three
Two spheres can only connect in a line. There is one relationship: A connects to B. Add a third sphere and suddenly you have choices. C can extend the line (A-B-C), creating a corridor. Or C can branch off B at an angle, creating an L-shape. Or C can connect to A, creating a triangle with B as the bridge.
Each layout produces a fundamentally different spatial experience:
Linear (A-B-C). A corridor. Each sphere is a room you pass through to reach the next. Good for sequential experiences — a wellness circuit, a production line, a gallery walk. The middle sphere becomes a transitional space, which is actually a powerful design tool. Think of it as the hallway that is also a room.
L-Shape. Two wings off a shared node. The corner sphere serves double duty as a connector and a functional space. This is the natural layout for separating public and private functions — office wing and living wing, growing wing and processing wing.
Triangle. Three spheres, each connected to both others. This creates a loop — you can circulate without backtracking. Triangular clusters feel larger than their square footage because movement through them is continuous, not dead-ended.
Four and Beyond
At four spheres, the possibilities multiply again. A few configurations worth thinking about:
The T-Shape. Three in a line with one branching off the center sphere. The center becomes a true hub — a node that connects to three other spaces. This is the first configuration where one sphere functions purely as circulation and distribution, like a foyer in a traditional house.
The Square. Four spheres in a 2×2 grid, each connected to its neighbors. Two loops, four connections. This is the densest cluster — maximum interior volume in minimum footprint. It also creates a natural courtyard effect if the connections are door panels rather than fully open passages.
The Star. One central sphere with three or more satellites. The hub-and-spoke model. The center sphere is the common room, the gathering point, the shared resource. Each satellite is a private or specialized function. This is the configuration that most closely resembles traditional building design — a central hall with wings.
Mixed Functions Get Interesting
The real power of clusters emerges when each sphere serves a different purpose. A single-function cluster (four identical offices, for example) is useful but predictable. A mixed-function cluster is where things get compelling.
The Wellness Compound. Saunosphere (dry heat) → Thiosphere (cool-down lounge) → Immosphere (cold plunge) → Agrosphere (herbal garden for post-session tea). Four spheres, four experiences, one integrated wellness loop. Each sphere is independently climate-controlled because each sphere is structurally independent.
The Maker Space. Ergosphere (workshop) → Thiosphere (materials storage) → Ergosphere (finishing room) → Thiosphere (showroom/office). A complete small-batch production facility that fits in a backyard.
The Guest Compound. Three Thiospheres as sleeping units, each with their own entrance, connected to a central Agrosphere that serves as a shared kitchen garden and gathering space. An Airbnb-scale hospitality operation built from modular components.
Site Planning
Clusters require more thought about site placement than single spheres or duos. A few principles:
Foundation independence. Each sphere sits on its own foundation points. Clusters do not share foundations. This means your site needs to accommodate multiple foundation sets, but it also means you can work with uneven terrain — each sphere can be leveled independently.
Connection tolerance. Door panel connections have built-in tolerance for slight misalignment. You do not need survey-grade precision when placing foundation points. If each sphere is level and the spacing between foundations follows the standard dimension, the door panels will align.
Access paths. Think about how people and materials reach each sphere during construction. Building a four-sphere cluster is not like framing a house where you work from one corner outward. You are building four independent structures and connecting them. The build sequence matters — you generally want to build from the center outward so that connection points are accessible.
Drainage and services. Water flows downhill. If your cluster includes a Saunosphere or Immosphere (water-intensive uses), plan your drainage paths before you place foundations. Same for electrical runs — while each sphere can be independently powered (solar, battery, grid connection), running conduit between spheres is easier during construction than after.
Scalability Is the Point
The cluster model does not have a theoretical maximum. Five spheres. Ten. Twenty. At some point you are building a village, not a building — and that is precisely the idea.
The modular system scales without redesign. Every connection is the same connection. Every foundation is the same foundation. Every sphere is the same construction process repeated. The complexity of a twenty-sphere campus is not twenty times the complexity of a single sphere. It is the same complexity, repeated twenty times, with connection planning layered on top.
This is fundamentally different from traditional construction, where scaling up means new engineering, new structural calculations, new everything. Here, the engineering is solved once at the module level. Scaling is a layout problem, not a structural problem.
Start Small, Think Big
The practical advice: start with one or two. Learn the build process. Understand the spatial experience. Then expand.
Every sphere you add connects to the system you have already built. No demolition. No renovation. No starting over. Just another module docked to the cluster.
That is what modular means in practice — not just "made of modules," but "growable by modules." Your building is never finished. It is just current.
