🚫 Common Mistakes to Avoid

1. Over-cluttering open spaces – defeats the purpose of an open-concept design.

2. Underestimating storage needs – large flats still need hidden storage.

3. Choosing aesthetics over function – some premium finishes may be high-maintenance.

4. Ignoring acoustics – large open layouts can echo without sound control.

5. Skipping contingency funds – luxury upgrades often lead to hidden costs.
