Domain House is situated on a prominent spur to the east of the Domain. Constructed in 1908, it is probably the second most prominent structure, overlooking the Cadman Bath House, the main bowling greens, and croquet lawns. The verandas provide extensive views over the Matamata-Piako and Hauraki plains.

Domain House was built as a Tea House/Tea Kiosk and proved to be popular during its first years, however its use gradually declined. This was possibly due to the lack of flat area and difficult accessibility. The business eventually closed in 1923.

The building has housed various businesses since and is now currently vacant. It is available for hire for small events - contact Council on 07 884 0060 for more information.
