Designed for deck-led holiday retreats and one-bedroom guest sites
The exterior imagery makes the relationship between glazing, entry and an outdoor platform worth discussing early. A deck can extend how guests spend time outside, but its size, finish and supply scope should be developed separately from the cabin's floor area. Inside, map the lounge and bedroom privacy against that outdoor route. With the same specified 8.94 × 3.48 m external dimensions as MG3-31A, the B variant gives you a design comparison without changing the headline room mix.
Plan the rooms and the complete footprint
The MG3-31B design area is 31.11 m². Use the room drawing to relate that area to furniture and clear walking routes.
The external building dimensions are 8.94 m long, 3.48 m wide and 3.2 m high. These describe the building envelope; allow additional space for the approach, any requested platform and access to the service connections.
Choose MG3-31B for the actual exterior and room arrangement that suits your plot. Compare MG3-31A directly, then move to MG3-40A or MG3-40B if a longer single-bedroom-and-lounge cabin is needed rather than a different look at the same size.

A coordinated modular envelope and interior
Our modular-home system brings floor, wall and roof components into a coordinated building arrangement. The construction approach includes a galvanized light-steel framework, insulation layers and exterior cladding, with the selected glazing, interior panels and bathroom components developed into the project specification. The module range includes PU insulation and integrated bathroom concepts; the final build-up and equipment schedule follow the chosen configuration. Discuss seasonal temperatures, moisture exposure, power and water connections with us so the envelope, interior finishes and service requirements are considered together.

From factory-prepared components to the site
The modular system allows the building to be considered as a coordinated set of components rather than a collection of unrelated site materials. We review the transport arrangement, unloading position, assembly sequence and service interfaces with the project brief. A container-based component shipment and a completed-unit delivery create different requirements for the site, so the selected method should be agreed before scheduling local equipment or labour. Read our guide to the modular building envelope for the questions to resolve during selection.
Delivery planning and a comparable quotation
For this modern modular retreat cabin, start with the destination, number of units, intended use and preferred room arrangement. The 3.48 m external width and 8.94 m length are useful inputs to the delivery review, alongside the final shipment configuration. We coordinate the agreed supply boundary with transport, unloading, supports and site utilities. Read the shipping and site-access guide before fixing an unloading position.
The quotation follows the chosen MG3-31B configuration: room fit-out, glazing and insulation requirements, bathroom or kitchen equipment, finishes, ordered quantity and delivery scope. A comparable quote uses the same inclusions and destination assumptions. Send a drawing or site sketch with the project quotation checklist so we can identify the options that matter to your use.
