一位欧洲作者分享了自家房屋装修中的基础设施建设经验，提出基础设施建设应遵循“现在成本低、未来改造成本高则提前配置”的原则1。该文章将建筑基础设施与云基础设施对比，强调建筑物变更成本远高于软件，因此应在难以改动的层面预留充足容量，即使大部分时间处于低利用率状态1。
在具体的装修实践中，作者为raclette（奶酪火锅）设置了专用电路，在客厅地板中嵌入专用20A电路，用于连接3至4台raclette机器，在230V电压下约4.6kW，该电路在官方电气图上标注为“Prise Raclette”并配有奶酪图标1。同时，作者为面积约12.5平方米的花园小办公室铺设了8根单模光纤连接至主屋，办公室配备5G6电力馈线（5根6mm²导体：三相、零线、地线）及额外5G2.5线缆1。
从整体房屋配置来看，该房屋配备3×400V + N供电、Cat6布线、23块太阳能板和20kWh电池储能，本地数据存储为16TB冗余存储，并备份至两个不同云服务商1。作者承认35mm线管安装时未留足够冗余拉线绳，后来修订标准为“拉线绳即基础设施，第二根即冗余，线管永远不嫌大”1。
An author in Europe has shared insights on home infrastructure development, advocating for the principle of provisioning early when current costs are low but future retrofitting costs are high 1. Comparing building infrastructure to cloud infrastructure, the author emphasizes that altering buildings is far more expensive than modifying software, meaning ample capacity should be reserved in hard-to-change layers even if utilization remains low most of the time 1. As a practical example, the author embedded a dedicated 20A circuit into the living room floor to power three to four raclette machines, delivering approximately 4.6kW at 230V 1. This specific circuit is officially marked as "Prise Raclette" on the electrical plans, complete with a cheese icon 1.
Beyond the living room, the author installed eight single-mode fiber optic cables to connect a roughly 12.5-square-meter garden office to the main house 1. This office is equipped with a 5G6 power feeder, consisting of five 6mm² conductors for three phases, neutral, and ground, along with an additional 5G2.5 cable 1. The entire house features an over-provisioned power infrastructure, including a 3×400V + N power supply, Cat6 wiring, 23 solar panels, and a 20kWh battery storage system 1. For data management, the setup includes 16TB of redundant local storage, which is backed up to two different cloud providers 1.
Reflecting on the construction process, the author admitted to not leaving enough redundant pull strings during the installation of 35mm conduits 1. Consequently, the author revised their standards to dictate that "pull strings are infrastructure, a second one is redundancy, and conduits are never too large" 1.
