Planning two homes on one block? Here's the number people often underestimate: everything outside the house price.
Dual occupancy and townhouse projects can involve far more than the cost of constructing the dwelling.
Depending on the site, there may be surveying, town planning, engineering, drainage, authority requirements, electrical upgrades, water and sewer works, driveways, subdivision costs, demolition and specialist reports to consider.
That's why feasibility needs to happen before someone spends heavily developing a plan they assume will work.
If you're looking at a dual occupancy or townhouse opportunity in Frankston, Langwarrin, Bayside, Pearcedale, the Mornington Peninsula, Warragul or Drouin, do your due diligence early.
The cheapest problem to solve is usually the one you identify before committing to the project.
