Transportable modular housing

A preliminary system conceived so that individual modules could be fabricated and transported separately, then assembled on site as independent homes or combined in multi-level configurations.

Discuss modular design on Upwork
Design status: preliminary concept and feasibility development. Detailed structural analysis, final sizing, connection design and full code verification were still required before construction.

The central idea

Each module was treated as a transportable unit with a repeatable structural and architectural language. At the destination, units could be positioned individually or connected to create larger and taller arrangements.

The concept explored transport dimensions, off-site fabrication, lifting and positioning, defined connection zones, external access and interfaces for the enclosure and building services.

Preliminary development

01 · Module

A repeatable envelope compatible with separate transport.

02 · Frame

HSS beams, columns and secondary floor members.

03 · Connections

Defined zones for horizontal and vertical assembly.

04 · Configurations

Independent, paired and stacked arrangements up to three levels.

Issues identified for detailed design

  • Final gravity, wind and seismic actions for the project location.
  • Member sizing and local verification around openings.
  • Lifting, transport and temporary-condition checks.
  • Detailed bolted or welded connection engineering.
  • Foundation interfaces, tolerances and on-site assembly sequence.
  • Waterproofing, thermal and building-services coordination.

Value of the concept stage

The preliminary work created a clear basis for further architectural and structural development. It established the transport-and-assembly logic early, exposed the critical connection and coordination questions, and provided a visual system that could be evaluated before investing in full detailed engineering.
