How to choose the perfect joiner for your space
Before purchasing your Roomi Joiner, here are a few things to consider:
Intended use: Consider how you plan to use the Joiner. Whether it’s for residential, commercial, or recreational purposes, understanding your needs will help determine the ideal layout and features. A Joiner for a family home may need more bedrooms and bathrooms, while one for a workspace could focus on open-plan areas and office space.
Connectivity and flow: Since a Joiner involves connecting two units, think about how the space will flow. Will the connection between the two units suit your desired layout? Consider factors like how the rooms will connect and if the layout promotes a natural flow for movement and functionality.
Size: The Joiner comes in a variety of configurations to suit different needs. From a 1-bedroom setup to a 3-bedroom layout, we offer flexible options to match your requirements. This allows you to pick the right size based on what you want out of your space.
