Terms & conditions.

01About these terms

This website and the Shouse Designer are operated by Modular Buildings Australia Pty Ltd (ABN 56 680 040 313). By using them you agree to these terms.

This page is a plain-English summary. The full MBA Terms & Conditions (version 3.2.1, effective October 2026) — which you accept when you create a Shouse Designer account, and which are attached in full to every estimate and quote — are the governing document and prevail over this summary wherever the two differ. Read them at shousedesigner.com/terms.

02The Shouse Designer

You need a free account to use the Shouse Designer. With it you can open designs, view them in 3D, place a design on your block, try colours and comment, and those choices are saved. Changing a design itself — walls, bays, windows and doors, fixtures, cladding and finishes, rooms and structure — needs a Shouse Designer subscription: $29/month inc GST, paid monthly in advance on the same date each month and renewing automatically until you cancel, with a tax invoice emailed for every payment. Cancel anytime. You keep editing to the end of the month you have paid for; after that your designs stay, view-only. No part-month refunds, except where the law requires. You can withdraw a cancellation any time before it takes effect. If a payment fails, editing pauses until it is paid. Your designs stay. If the subscription price changes, we will email you at least 30 days before it applies to you, and you can cancel before then. If MBA stops offering the subscription, or ends yours for a reason other than a breach of the Terms, MBA refunds the unused part of the month you paid for. Accounts that existed before the subscription began keep free editing for 11 days and are never charged unless they choose to subscribe. The subscription covers editing only — every other product and service is priced separately.

Designs, floor plans, renders, 3D models, specifications and any kit price shown on this website or in the Designer are concept information: they are not structural engineering, working drawings or approval documentation, and renders are artistic visualisations with indicative colours and details.

Site boundaries, setbacks, levels, sun studies and overlays shown in the Designer come from public mapping. They are indicative, not a survey, and current only as at the date they were obtained. An item the mapping did not assess is not an item that passed.

03What MBA does, and does not do

MBA is a technical coordination and building-system supply company. MBA coordinates engineering, energy assessment and drafting through qualified professionals, supplies the engineered building system and its components, and provides technical documentation and support. MBA is not your builder, certifier or approval authority, does not supervise construction, and does not guarantee any approval outcome — building and planning decisions rest with the relevant council, certifier or authority.

04Kit prices

Kit prices shown on this website are “from” prices in Australian dollars including GST. Engineered shell kit — frame, roofing, cladding, flashings and fasteners. Delivery, slab, window and door units, services, labour and internal fit-out are additional. Your kit price is confirmed by a formal quotation after site-specific engineering. Specific inclusions are governed by the formal quote, the bill of materials and the approved project documentation.

05The staged services

The paid services (the Shouse Starter Pack and Stage One (Preliminary Drawings)) are priced as displayed in the Shouse Designer at the time of order, inclusive of GST. Paying for a service forms an agreement for that service only: you may stop at any stage and keep the documents you have paid for.

A Shouse Starter Pack is a review of your design and your block from public mapping and the information you provide. It is indicative, is not a supply quotation, not engineering and not approval advice. MBA reviews each design before issuing one; if MBA cannot issue an estimate for a design — for example because it falls outside MBA’s building system — MBA will tell you why and refund the fee in full, or offer the choice of a refund or an amended design. The Terms call it the “Detailed Estimate”.

Stage One (Preliminary Drawings) establishes early project direction. The drawings are prepared for pre-lodgement and planning discussions and may form part of a planning application where appropriate, subject to local requirements. They are conceptual in nature and are not final construction documentation.

Stage Two (Engineering) is part of the Engineered MBA Kit: it is included in the kit price and is not sold or priced separately. It turns the approved direction into coordinated technical information — site-specific structural engineering, the energy assessment and drafting coordination — produced by qualified professionals and coordinated by MBA. It begins when you pay the kit deposit stated in your estimate or quote, which is credited in full to your kit. Engineering relies on your soil test, site information and the conditions you disclose; MBA is not responsible for inaccurate reports or undisclosed site conditions.

06Quotes and kit supply

A formal supply quotation is issued by MBA only after engineering, against a named engineering release. It is an offer valid for the period stated on it and is accepted per the full terms. Until then every price is indicative, and MBA may adjust pricing where supplier costs, freight, regulation, engineering revisions or customer-requested changes move — with notice before proceeding.

Delivery dates are estimates until suppliers and freight providers confirm scheduling. You are responsible for safe truck access, unloading equipment where required, storage after delivery, and inspecting the delivery against the bill of materials promptly — the full terms set out the inspection period and process. Additional lifting equipment or re-delivery caused by site access remains your cost unless agreed in writing.

07Your responsibilities

You are responsible for the land, permits and approvals, soil testing, site preparation and access, engaging your builder and trades, the slab and footings, utilities and services, construction supervision and site safety. MBA relies on the accuracy of the information you provide about your site.

08Payments and refunds

Payments follow the issued quote or invoice schedule, and MBA is not required to begin work, release documentation or release materials until cleared funds are received. Payments are generally non-refundable once work has commenced, and the kit deposit that starts the engineering is non-refundable once paid — it is credited in full to your kit if you proceed. Where work has not commenced MBA may refund at its discretion, and where supplier pricing materially changes before order confirmation and you decline to proceed, MBA may refund amounts paid for undelivered products. Shouse Designer subscription fees are not refunded for part months; cancelling stops the next renewal. Nothing in these terms limits your rights under the Australian Consumer Law.

09Your designs and our system

Designs you create in the Shouse Designer are yours to use for your project with MBA. They are produced by arranging MBA’s building system inside MBA’s software, so they are not exclusive — MBA may supply the same or a similar design to any other customer, and you grant MBA a licence to use your design for its business, including quoting and engineering it.

The Shouse Designer, the MBA building system, the component catalogue, our drawings, documentation formats and this website remain the intellectual property of MBA and may not be reproduced or used to manufacture kits by others without written permission.

10Warranties and liability

Materials carry the warranties of their manufacturers (for example BlueScope and Stramit) and MBA assists with warranty claims. Nothing in these terms excludes rights that cannot be excluded under the Australian Consumer Law. To the extent permitted by law, MBA is not liable for decisions made in reliance on concept information before project-specific documentation and engineering are completed, or for construction outcomes, which remain the responsibility of you and your engaged contractors.
