We know "how much does it cost?" is always the first question on everyone's mind. The reality is that your final build budget is heavily dictated by your land. Even if two homes look identical from the outside, site-specific variables — such as soil classification, local wind ratings, block slope, and utility connections — will significantly alter construction costs. Our Project Support service is designed to investigate these variables up front, ensuring your project pricing is transparent and accurate.

The 25% rule of thumb

To help you map out your total project budget, one way is by using the industry-standard multiplier. Across the Australian residential construction sector, the structural frame and weather-tight shell — the kit itself — typically represent between 25% and 33% of a standard home's final turnkey cost.

我们知道"要多少钱？"始终是每个人最先想到的问题。事实是，您的最终建造预算很大程度上取决于您的土地。即便两栋住宅外观完全相同，场地专属变量——如土壤分类、当地风力等级、地块坡度及水电接驳——都会显著改变施工成本。我们的项目支持服务旨在预先调查这些变量，确保项目定价透明准确。

25% 经验法则

为帮助您规划总项目预算，可采用行业标准倍数法。在澳大利亚住宅建筑行业，结构框架与防水外壳——即套件本身——通常占标准住宅最终交钥匙成本的 25% 至 33%。

When you purchase a GanMu kit, there are two paths to bring your project to life.

Path 1 — Owner-builder (DIY / owner-managed)

Take on the role of construction manager and save thousands in builder margins. You'll still need to engage licensed trades for specialised work (plumbing, electrical), but you organise the subcontractors and oversee the site yourself. With a GanMu kit, the steel walls arrive perfectly straight and lock together seamlessly, so physical assembly is fast and straightforward.

Path 2 — Registered builder (done for you)

Prefer a hands-off approach? Engage a fully licensed, registered builder to manage the project from slab to turnkey handover. We have a list of experienced builders and will be happy to recommend them to you.

Queensland compliance (QBCC)

Building in Queensland requires an Owner Builder Permit from the Queensland Building and Construction Commission (QBCC) for any residential building work valued at over $11,000. This permit establishes you as the principal contractor, making you legally responsible for coordinating trades and ensuring compliance with the National Construction Code.

GanMu documentation — including precise structural specifications and engineering details — provides the technical foundation required to support your building approval process and assist in ensuring your project meets local regulatory standards.

购买 GanMu 套件后，您有两条路径实现项目落地。

路径 1 — 自建业主（自行管理）

担任施工管理者角色，节省数千元的建筑商利润。专业工程（水管、电气）仍需聘请持牌技工，但由您自行组织分包商并监督现场。使用 GanMu 套件，钢制墙体到货即笔直精准、无缝拼接，实际组装快速简便。

路径 2 — 注册建筑商（全程代管）

希望省心？聘请全牌照注册建筑商，从楼板到交钥匙全程管理项目。我们备有经验丰富的建筑商名单，乐意为您推荐。

昆士兰合规（QBCC）

在昆士兰州，任何价值超过 $11,000 的住宅建筑工程都需向昆士兰建筑与施工委员会（QBCC）申请自建业主许可。该许可确立您为主承包商身份，使您在法律上负责协调技工并确保符合国家建筑规范。

GanMu 的文件——包括精确的结构规格与工程细节——为您的建筑审批流程提供必要的技术基础，协助确保项目符合当地法规标准。

It is a common misconception that living in a steel-framed home means enduring an oven in the summer and a fridge in the winter. Because our systems are engineered from day one as Class 1a habitable dwellings, they are designed to achieve a mandatory 7-star NatHERS energy rating.

We ensure year-round comfort by layering base insulation and thermal break strips on the framing, alongside site-specific bulk insulation tailored to your climate zone and glazing.

This comprehensive thermal envelope is also the secret to proper condensation management. By combining vapour-permeable sarking membranes, thermal breaks, and NCC-compliant ventilation, we prevent warm, moist air from interacting with cold steel — the leading cause of condensation in metal structures.

As an added benefit, this thick layer of insulation provides excellent acoustic dampening, turning the sound of heavy rain on your steel roof into a pleasant background hum rather than a deafening roar.

人们常误以为住在钢结构房屋中意味着夏天像烤箱、冬天像冰箱。由于我们的系统从设计之初就按 Class 1a 可居住住宅标准工程化，因此必须达到 NatHERS 7 星能源评级。

我们通过在框架上分层铺设基础隔热层与热断桥条，并结合针对您所在气候区与玻璃配置的场地专属体积隔热，确保全年舒适。

这套完整的热工围护系统也是有效控制冷凝的关键。通过结合透气防水膜、热断桥及符合 NCC 的通风设计，我们防止温暖潮湿的空气接触冰冷钢材——这正是金属结构冷凝的主因。

额外优势是，这层厚实的隔热材料具备出色的隔音效果，将钢屋顶上的暴雨声化为悦耳的背景低鸣，而非震耳的轰响。

When it comes to the exterior of your GanMu home, you have the freedom to design a look that perfectly matches your environment and personal style. We proudly utilise COLORBOND® steel for our roofing and cladding options, giving you access to their complete range of iconic designer colours.

Inspired by the Australian landscape, these high-performance finishes are engineered to resist peeling, flaking, and blistering under the harsh sun. Whether you are aiming for a striking, modern architectural contrast with dark shades like Monument®, or a seamless natural blend with classic tones like Pale Eucalypt®, you can customise your kit to suit your exact vision.

在 GanMu 住宅的外观方面，您可以自由设计出完全契合环境与个人风格的外貌。我们的屋面与外墙包覆选用 COLORBOND® 钢材，让您享有其完整的经典设计师色系。

这些高性能饰面灵感源自澳大利亚风景，经工程设计可抵御烈日下的剥落、起皮与起泡。无论您追求 Monument® 等深色调带来的强烈现代建筑对比，还是 Pale Eucalypt® 等经典色调的自然融合，都可按您的确切构想定制套件。

We believe a building is only as reliable as the materials used to create it. To ensure your home stands up to the harshest Australian conditions, GanMu sources material from the nation's most trusted, tier-one steel and component manufacturers.

Our supply chain includes

• BlueScope Steel — premium, high-tensile structural steel and genuine COLORBOND® cladding.
• Lysaght, Metroll, Stratco, Stramit & Steeline — Australia's premier roll-formers, manufacturing precision steel framing, roofing, and structural components.

我们相信，建筑的可靠性取决于所用材料。为确保您的住宅能经受澳大利亚最严酷的环境考验，GanMu 从全国最受信赖的一流钢材与部件制造商采购材料。

我们的供应链包括

• BlueScope Steel — 优质高强度结构钢及正品 COLORBOND® 包覆材料。
• Lysaght、Metroll、Stratco、Stramit 与 Steeline — 澳大利亚顶尖的辊压成型企业，生产精密钢框架、屋面及结构部件。

Once your final design is approved and engineering is complete, the manufacturing of your GanMu steel kit typically takes between 4 to 6 weeks. While a full owner-builder project generally spans 6 to 12 months from initial planning to final handover, our precision-engineered frames give you a massive advantage in reaching the critical lock-up stage.

Lock-up is the milestone where your external walls, roof, windows, and doors are installed, making the structure completely weatherproof and physically secure. Reaching lock-up quickly is vital because it protects your materials from weather damage and theft, allowing internal trades — like plumbers and electricians — to commence their work without being delayed by external weather conditions.

最终设计获批且工程设计完成后，您的 GanMu 钢结构套件生产通常需 4 至 6 周。完整的自建项目从初步规划到最终交付一般历时 6 至 12 个月，而我们的精密工程框架让您在抵达关键的"封闭"阶段时拥有巨大优势。

封闭是指外墙、屋顶、门窗全部安装完成的里程碑，使结构完全防水且物理安全。快速抵达封闭阶段至关重要，因为这能保护材料免受天气损害与盗窃，让水管工、电工等内部工种可以开工，不再受外部天气条件拖延。
