Frequently asked questions
- How much does the TR3M modular house cost?

- How long does it take to build a TR3M?
- From order to moving in, expect approximately 6 months. Factory production at the DWELLII works takes around 8–10 weeks; on-site assembly is completed within a matter of days.
- Do I need planning permission for the TR3M?
