Key Takeaways

• Check local building regulations and apply for permits in advance. In Denmark, review the local plan (byggeri) and existing secondary building area to determine if a permit is needed. Unpermitted structures may require neighbor approval, affect property sales, or even lead to fines (~7500 DKK/week) if reported.
• Rent the right tools. If you're inexperienced, opt for longer rental periods to avoid rushing. A few extra hours or a day usually costs just a bit more, while late fees can be steep.
• Ask experienced staff for advice. For example, consult them on concrete nails, paving stones, or self-leveling compounds. (A staff member who used to work in construction gave me great tips on installing concrete nails!)
• Notify and maintain good relations with neighbors. Construction noise, equipment, and temporary obstructions can be disruptive. My neighbors were supportive, even checking in and complimenting our progress.
• Ensure precise measurements (right angles, edge distances, etc.). Poor foundational work can complicate later stages.
• Get a reliable helper.
• Prioritize safety.
