In-house design, architecture and construction — one Sydney team
On a difficult block, the biggest cost blowouts happen in the gap between the person who draws the house and the builder who has to get it out of the ground. We keep design, construction and trade services inside one director-led group so buildability, engineering and price are resolved together.
Varloch Design
Concept, DA and construction drawings produced alongside the builders who price and build the job — so structural engineering, rock excavation and council controls are solved on paper before site work starts.
Varloch Services
Sydney plumbing, sub-soil drainage, stormwater rectification and scheduled home maintenance run by the same licensed trade crew that builds Varloch homes.
