The Porter House Hotel is a 5 level (plus basement) historic building in Castlereagh Street Sydney, its previous use and name being Dixon and Sons Tobacco Factory.
The completed building forms part of a newly constructed, major complex including a multistorey hotel and residential tower. 
Structural rectification was necessary before any refurbishment could commence including progressive propping and rebuilding of the stone façade, re levelling of the floors some of which were 150mm out of level and steel strapping of timber columns for strength and fire rating purposes.
The building has been repurposed into offices, conference rooms, restaurants, coffee shop and bars. 
All services were renewed to comply with current fire regulations, and as the original floors were exposed and left visible from below, new floor finishes were fixed to the original flooring for décor and sound insulation purposes.
This historic building has been well preserved, forming part of a modern hotel complex whilst, retaining its historic significance and character.
