How long does an upper floor extension take to complete?

Upper floor extension timeframes typically range from 12 to 20 weeks, depending on project size, complexity, and approval processes. Simple extensions over existing single-storey homes generally take less time than complex multi-room additions or those requiring significant structural modifications.

The timeline includes several phases: initial consultation and design (2-3 weeks), council approval process (4-8 weeks for DA, 2-3 weeks for complying development), and construction phase (8-12 weeks). Weather conditions, material availability, and any unforeseen structural issues can affect these timeframes.

At Curtis Construction, we provide detailed project schedules during the planning phase and maintain regular communication throughout construction. Our hands-on project management approach helps minimise delays and keeps your extension progressing smoothly towards completion.
