Things to know before you go for granny

A granny flat is always a noble investment not only because it gives space and property value without altering the current home status, but it also gives extra space for extended family members and fetches additional rental value. Regulations permit only one granny flat on a property with a maximum 60 square meters floor area and 3.8 meters height respectively.

How long does it take to finish the construction process?

We aim to have our building completed within the promised time period and do everything possible to achieve that. However, adverse weather, the perplexity of the project, site conditions, and other unexpected inevitable causes may hamper our work. If your project has any such delays, we keep you informed on the progress.
