Common mistakes to avoid
1. After had, always the past participle
With build, the Past Simple and the past participle are the same (built), so I had built is easy. But many irregular verbs have two different forms: I had gone, not I had went; I had seen, not I had saw.
2. Yesterday I had gone to the cinema ❌
Use the Past Perfect only for the earlier of two past actions. For one past action, the Past Simple is enough: Yesterday I went to the cinema. With build: built for one action, had built for the action that came first.
3. 'd + past participle = had
'd can mean had or would. Look at the next word. 'd + past participle = had: I'd built = I had built. 'd + base form = would: I'd build = I would build.
