You can ask the person who sold you the property to confirm who built your home. For example, if the seller contracted the builder, they could likely tell you the builder and give you a copy of relevant documents. You should confirm the correct identity of the builder by obtaining and reviewing the following documents that will likely list the name of the builder:    Building permit – if one exists.   Domestic building insurance certificate – if one exists.  Domestic building contract – if you can obtain a copy.  These documents may be included in the bundle of documents you received when you purchased your home as part of the “section 32 vendors statement” attached to the contract of sale.
