Prefab Housing Module Design Brief V01, 03/08/22 1 Matthew Williams Director, MWA 19 Dumbarton Street McMahons Point, NSW 2060 M 0410232939 E info@mw arch.com.au W www.mw arch.com.au GamaBella Building Successindo Registered Company Details to be Provided Registered Company Contacts to be Provided Wednesday, 3rd August, 2022 Dear Bella, RE: OUTLINE BRIEF AND REQUEST FOR FEE PROPOSAL, CONCEPT DESIGN SERVICES PREFABRICATED ‘REMOTE HOUSING’ DESIGN, TRANSPORT AND ASSEMBLY CONCEPT Thank you for our recent discussions regarding our intent to initiate a Flat Pack, Remote Housing Construction Company, selling unique Housing products directly to Regional Communities and Land Owners in Far North Queensland and possibly beyond. We are pleased to understand that you have good experience and a good track record in the design, fabrication and shipment logistics for such a business model. We provide here, for your information, an outline Brief for an Example Design for a Housing Module, a brief outline of Design Compliance Criteria, and an approximate Scope and Timeline for an 8 week design Programme, to allow us to obtain a ‘Proof of Concept’ Design for the Product based on our specific Criteria.
Design WeDeliveryCriteriaexpecttoutilise
a flatbed truck with on board lifting gantry crane, that can deliver the Product into very remote locations. This Truck can be identified as part of the Design Phase, however an indicative example is shown at left, and link to the Truck Description as per below. This may change, as we agree the most appropriate design module and tonnage.
https://lvtruckcranes.com.au/product/ferrari-truck-crane-7261c/ We expect that House Modules will be constructed in locations that will be at times very remote, but reasonably clear of debris and obstruction at the building site (at least, at time of arrival of the House Module), such that the Truck can drive to and park immediately adjacent the designated Building Site. For this reason, we prefer a non articulated Truck as per the example shown at left, such that the Truck is more capable of traversing uneven ground to reach the designated Construction Site.
Construction Crew: We expect that the whole of the Housing Module, will be able to be assembled, secured and finished on site, by a maximum of two trained and skilled crew, in 3 5 days. This constraint is set, as this is the available number of seats in the Truck, transporting the modules to the Site. The Crew will bring all the required tools and equipment for this purpose with them, likely in a large Toolbox included to the Truck. This will limit the type of equipment that can be transported and used at the Construction Site. As we intend to set up this Business in Australia, as a Franchise Opportunity, for local indigenous People, to train and orient themselves to operations of the Business, and Delivery and Construction of the Modules, the method of Construction should be relatively straight forward and easy to understand, and not rely on any specialist skills that need to be built up over time. Simplicity in construction is important both for speed of construction and improved availability of Construction Workers who can successfully deliver and build the Product.
We expect that 1 Truck Load will include all of the House Module Components, such that the Truck makes one trip only to the Construction Site.

A steel screw pile example is provided here: https://plasticinehouse.com/how-to-build-screw-pile-shed-foundation/
Once the Truck is stabilised, a second constraint is that the Truck Lifting Gantry will lift and manouver the various House Module Panels into place, and stabilise these panels and Modules, as a team of maximum two persons secure and fixe the panels together. As such, the whole of the House Module needs to be built within reach and below height of the selected Truck Gantry Crane As can be seen in the link example above, there are a range of options for length of reach etc. It is reasonable to presume at this stage, that the Truck will be parked on adequately stable ground (we will determine these truck parking ground stability requirements later).
earlier, we assume this in ground structure will quickly establish a stable, level frame onto which the typical Housing Module Panels can then be placed and secured from the Truck Gantry Crane. We expect the Housing Module to account for any inground movement and provide generous tolerances and structural flexibility, such that requirements for sign off of the in ground structure are not overly onerous.
How can we certify the in-ground structure? Remote Test?
Footings & Foundations: We expect the Modules will be constructed on a range of ground types, from soft, grassy soils, to hardened gravel surfaces, to sand. As such, we need a good level of variability in the Footing design, that can be pre selected based on the nominated ground condition for the building site, that then extends up to form the substrate Frame for a Typical Housing Module to be built on top of this in ground frame or structure. As well, this in ground structure needs to be easily constructed as part of the 3-5 day work phase, by the 2 crew attending to the Construction Site, with the Truck. There may be attachments that can be fitted to the overhead Gantry Crane that can assist with either excavating or boring piered foundations, or driving or screwing mechanical piles. Any structure located into the ground needs to be very robust in terms of resistance to water damage. We do not think it economic to construct concrete footings at a work site, due to time delays in preparation of concrete, complexity in setting reinforcing and pouring footings, and time taken up by curing the concrete. However, at this stage it should not be excluded as an option and can be considered amongst a range of other alternative strategies For example, the Gantry Crane could support a ‘Driven Pile’ option, to greatly speed up the time required to finish in ground works and establish the secure Housing Module base. A screw pile may be preferred to limit impact damage to the Gantry Crane Asassembly.mentioned

Good Views to Outside. Includes Entry. House Module Services: Because we anticipate House Modules will be located in very remote locations, we assume that there will be no in ground services available. Therefore, the House Module must ‘stand alone’ in terms of Potable Water Supply, Power Generation, Grey Water Treatment, Toilet Waste Containment and Treatment. The House can be Heated but will not be Air Conditioned. The external envelope of the House needs to be adjustable or operable to provide either a sealed internal air space for heating, or an open internal air space to encourage natural breezes and a good rate of air flow through all internal spaces. We assume data will be delivered to the House via the Owner’s Mobile Phones, however we can consider options for Data Technology as part of this Design Review process. We assume owners will utilise Mobile Phones for telecommunications. The internal of the House should be provided a good supply of Power outlets, as well as providing the option for Data Management within the House Framing. There may need to be the capability of Power Storage on Site, such that power to the House System can continue in periods of downturn of ordinary supply.
We expect the Housing Module will accommodate to groups of people, from small groups (2 4 persons), up to larger groups (say 20 persons). The Family Groups we intend to market to, can vary in size over time. As well, owner budgets can vary over time, meaning that Houses should be able to grow and enlarge, in different stages, without that growth impacting the integrity of the existing House Module, as new Modules are added.
Bathroom
We appreciate this certainly adds to the Design Complexity of the Design Requirement. However, we expect to be able to ameliorate the Design Impact of this requirement, by lessening demands of the design in other respects (as will be discussed later in this brief outline Document).
For Example, a Basic House Module, should fit on one truck delivery, as we have noted above, and comprise as follows:

Prefab Housing Module Design Brief V01, 03/08/22 4
Design Examples: Example #01: Marika Alderton House, by Architect Glenn Murcutt Located in Yirrkala Country, NW Tip of NT, on Gulf of Carpenteria This house is located in an environment typical for much of Far North Queensland. The below pink provides a useful article in understanding the relevant Design Parameters of this House. We like this Design because it is Modular; supports an outdoor Lifestyle; is Easy and Fast to Build, Touches the Ground Lightly; is constructed from hard wearing, lightweight materials; the design possibly conveys something sensitive to Australian Aboriginal Culture; The House adequately protects Occupants from the Environment; is Simple and Uncomplicated; is Expandable and Flexible.
Housing Module Roof: The Roof will be a very important part of the House Design, as it needs to perform a multiple of functions, as well as be easy to build (by prefab), easy to transport, easy to assemble on site, at the same time as being extremely durable, extremely weather resistant, and provide very good thermal flow resistance (as heat loads attempting to either ingress or egress the building). The Roof must also collect as much rainwater as possible and track it easily and safely to the on site water storage system.
TheMaintenance:wholeofthe house needs to be washable by a hand held hose, both inside and out. Materials and assembly must resist dust, condensation, moisture, insects, birds and nesting animals. Building Systems components (eg. Building Services items as listed above), must be easily removeable and easily replaceable by an unskilled person. It would make sense that if there is a fault with a service item, that a new item simply be delivered to the Site, with the owner then fitting that replacement item themself. Validation of fitment can be done via photograph and remote sign off.
Consider: Maintenance Works and Support as part of House Module Supply Contract? Weather Resistance: Australia has a very diverse climate. It can be very hot, and very cold. It can be very wet, and very dry. Remote housing in Australia can locate into any of these climates. Therefore, there needs to be a flexible system of thermal overlay into the Walls and Roofs, that can be adjusted in the Prefab Factory, to suit the ultimate location and performance requirement of that particular Housing Module. This is particularly relevant for the outer walls and roof. All external materials (Footing, Frame, Claddings, Linings, Roofs) need to be extremely weather resistant, and we cannot expect that any exposed surface will be cleaned, maintained or resurfaced. Any Building Systems deployed as part of the main Building Envolope, need to be very robust, strong and resistant to damage and wear (For example, sliding doos providing access to outdoor spaces). We will need to make intelligent decisions regarding exposure to fire, as it could be the case that some of the housing modules, are located in bushfire prone areas.
Internal materials need to have a very high level of integral weather resistance, as we expect that the ultimate House Module Design, will encourage outdoor living and an outdoor lifestyle.
We expect House Module Panels to arrive at site prewired, with all light fittings, power and data outlets, etc. preinstalled, with the solution being that perhaps each panel is connected together as the assembly of the Housing Module proceeds on site, such that the Electrical and Data Grid for the House then can be powered up and used once all the House Module Panels are connected together.
International Sale, unknown Designer or Fabricator What we like about this Design: Modular, Modular in Components (Eg. Kitchen Bench Module), Indoor / Outdoor, Lightweight, Flat Pack to Conserve Space. What we Don’t Like: The Flat Roofs. Flat Pack design is important because if we are intending to Fabricate the House Module units in Bali and then Ship to Remote Areas of Far North Queensland and Northern Territory, it makes sense to ensure that the House Modules can be packed efficiently and tightly into shipping crates. It should be such that those Modules can remain ‘packed’ until such time as they arrive at the Building Site, where the ‘packaging’ can then be broken down or removed, to allow the Gantry Crane to progressively extract separate Modules from the ‘Stack’, for lifting into position and Assembly. We anticipate that the basic House Module as outlined above, above can be purchased as turn key, in range $AUD100,000 to $150,000, with House Modules (as outlined Below), of varying Costs to be advised by You.
This House is available for Purchase as a Pre Fab Module, constructed in Bali and shipped to required Locations. What we like about this House: Indoor / Outdoor Lifestyle; Quality of Finishes; Elegant Steel Frame; Durability; Timeless Design; Functionality; Double Height; Access to Views.

adds significantly to the Design Complexity, we know that (a) most Rural Land Zonings allow only 1 and possibly 2 NCC Class 1 style Domestic Homes per Land allotment, (b) Aboriginal Families can grow and shrink over time, and can include Grandparents, Nieces, Nephew, Aunties, Uncles and Second Cousins and Friends, in addition to the Mother, Father and Children, (c) custodial care for Children and the Elderly is provided by way of a consolidated effort amongst all family members, within the Community, and (d) Shared Living is an acceptable lifestyle for our Customers.
Groundworks Concept Relevant Detail on how the approved Housing Module on ground subframe, footings and foundations are constructed on site and controlled for stability and setout in X, Y and Z dimensions and how the Design can adapt to a range of different Soil and Ground Conditions
Design Phase 8 10 weeks: As mentioned earlier, we hope to initiate and collaborate through an 8 10 week Design process, where we generate workable Design Concepts that, while low in detail for Construction, are resolved and purposed in terms of how the Design Concept meets the Criteria set out above. We hope to rely on your Expert Skills in creating this kind of Product, and hope that you are open to our feedback and Collaboration, as we progress the Design Concept Phase.

Design Phase Outputs
The latter of these, the Large Living module, could in fact be quite large, and accommodate common living activities for up to 20 persons or so. It may well be a gathering facility for a very expansive, final Module arrangement.
Assembly Concept Relevant Detail on how each of the approved Housing Module Panel and Partis Lifted, Placed, Propped and secured at the Construction Site, the order in which the Panels and Parts are put together, and the way in which each Panel or Part is fitted and secured to other Parts. Approximate Weight of each Part. Verification against selected Truck Gantry Crane Type and Reach. Preliminary Detail on Tooling Requirements for Remote Site Construction Works.
As such, we expect that we can ‘plug into’ and ‘add onto’, new modules, to expand the basic house module outlined above. This needs to be carefully defined in the Design Stage. For example, the Basic Module outlined above (single Loft bedroom), needs to be able to expand, by way of addition of another bedroom / Bathroom Module, that can be built either as integrating with the original House Module, or adjacent, and connected to, that original Module.
It may be the case that the range of Design Module Options, could expand to include: Large Kitchen Facility, Large Bathroom Facility, 2x bedroom Module, Connecting Walkways and Links, Large Laundry Module, Large Living Module.
