Let the garden guide the layout of a one-bedroom guest suite. Our MG3-40B provides 39.11 m² with a bedroom, living room and bathroom, offering a prefab cabin to develop around outdoor seating, landscape privacy and indoor comfort.

## Suggested applications

A private garden guest suite with an indoor lounge. A landscape-led resort unit with a separately planned platform. A one-bedroom retreat with equipment selected for the actual site.

## Designed for private garden retreats and landscape-led guest accommodation

The MG3-40B exterior imagery can help you think through the relationship between the building and an outdoor platform. Decide which rooms face the garden, where the entrance path goes and how guests reach seating outside. An appearance of solar equipment in a concept image is a prompt for a specification discussion, not an automatic off-grid package. The 11.38 × 3.48 m building footprint and the agreed equipment schedule should remain separate parts of the planning brief.

## Plan the rooms and the complete footprint

Source section: https://leaderspacehomes.com/products/modular-mg3-40b/#detail-2

The MG3-40B design area is 39.11 m². Use the room drawing to relate that area to furniture and clear walking routes.

The external building dimensions are 11.38 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 MG3-40B for the design and indoor-outdoor arrangement you want to develop. Compare MG3-40A at the same area, or MG3-31B if a shorter bedroom-and-lounge cabin is sufficient. Ask us to specify any renewable-energy equipment as a measured part of the proposal.

- [Modular Guest Suite for Longer Resort Stays](/products/modular-mg3-40a/): MG3-40A · 39.11 m² · 1 bedroom · living room · 1 bathroom.
- [Modern Modular Cabin for Deck-Led Retreats](/products/modular-mg3-31b/): MG3-31B · 31.11 m² · 1 bedroom · living room · 1 bathroom.

Open the drawings side by side and compare bedroom privacy, shared living space and the building footprint. The model code remains a reference for the exact configuration you ask us to quote.

## A coordinated modular envelope and interior

Source section: https://leaderspacehomes.com/products/modular-mg3-40b/#detail-4

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

Source section: https://leaderspacehomes.com/products/modular-mg3-40b/#detail-5

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](/resources/modular-building-envelope/) for the questions to resolve during selection.

## Delivery planning and a comparable quotation

Source section: https://leaderspacehomes.com/products/modular-mg3-40b/#detail-6

For this garden-facing prefab cabin, start with the destination, number of units, intended use and preferred room arrangement. The 3.48 m external width and 11.38 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](/resources/shipping-and-site-access/) before fixing an unloading position.

The quotation follows the chosen MG3-40B 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](/resources/project-quotation-checklist/) so we can identify the options that matter to your use.

## Frequently asked questions

### Does the design image mean the cabin is supplied off-grid?

Solar generation, battery storage and related equipment need a defined project specification. The image does not establish an included off-grid package or its capacity; share your expected loads and available site connections.

### What space does the MG3-40B configuration provide?

The design area is 39.11 m². Its room arrangement is 1 bedroom · living room · 1 bathroom.

### Where would this garden-facing prefab cabin fit best?

Choose MG3-40B for the design and indoor-outdoor arrangement you want to develop. Compare MG3-40A at the same area, or MG3-31B if a shorter bedroom-and-lounge cabin is sufficient. Ask us to specify any renewable-energy equipment as a measured part of the proposal.

### What changes the price of the MG3-40B?

The configuration, finish and equipment schedule, quantity and delivery scope determine the quotation. Share your destination and intended use so we can price the same defined scope you are comparing with other options.

### What should I send for a MG3-40B project proposal?

Send the country and site location, unit quantity, intended use, your preferred MG3-40B layout and a site-access sketch if available. Add any requested furniture, bathroom or kitchen equipment and the available power, water and drainage connections.

## Discuss your garden-facing prefab cabin
