If you want to build a modular home, you will need to understand Ireland’s planning and development system, as well as possible parties that may be involved. This is essential for anyone involved in construction, property investment, or land use of any kind. Of course, in most cases, it is just better to leave the above in the hands of a capable architect, planning expert or solicitor.
