The Modulus Cluster

An infinitely reconfigurable unit system for households in active discourse about density.

Plan set for base unit × 4 · expansion units sold separately, by us, gladly

The Modulus Cluster is a single repeating cube — 6" on a side, one entry per face pair — that stacks, rotates, and cantilevers off itself in any configuration the client's fence line and personal restraint can support. The plan set ships with four units and a connector system rated for up to nine before we begin, gently, to ask questions.

We do not consider this a compromise design. We consider it the only honest response to a client who cannot commit to a single elevation, a category of client this studio has served, without complaint, since the studio's founding.

On Reconfigurability

Each unit connects to any adjacent face via a keyed dowel system that permits full disassembly and reconfiguration without tools, a feature we describe to clients as "seasonal" and privately understand to be "for when the argument about the fence line resumes." The plan set includes three sample configurations — the Vertical Stack, the Cantilevered Wing, and a formation we have internally named the Compromise, which satisfies no one completely and is, for that reason, our best-selling layout.

Materials Note

Baltic birch plywood is specified for the base unit despite this studio's stated aversion to the word "plywood," on the grounds that a modular system lives or dies on dimensional consistency, and dimensional consistency is the one thing solid stock has never reliably given us. We have made our peace with this. Mostly.

Assembly Notes

Units may be reconfigured after initial assembly. The dowel connectors are rated for approximately 40 reconfiguration cycles before the client should consider this a sign.
Entry diameters vary by unit and by species targeted. Do not standardize across the cluster. The variance is the point.
Maximum tested stack height is 9 units. We have not tested 10. We do not intend to.
