Short answer: A complete design and permit package should cover the drawings, structural engineering, the energy report, the soil test and survey and, where needed, landscape design and the town planning application. Many advertised modular home prices cover the building only, so these costs arrive later. EcoPrestige’s Domestic One Stop package covers the design, engineering, energy report, soil test and survey for $16,200 incl GST, all inclusive, starting with $4,000 + GST.
What advertised modular prices often leave out
- Council and permit fees and external reports
- Site works: driveway, excavation, retaining walls, service connections and wastewater
- Bushfire (BAL) upgrades to windows and cladding
- Delivery beyond a set distance from the factory, and crane hire
- Design changes after the first plan
None of these are unusual. The problem is finding out about them after you have committed. Ask any supplier for a written list of what is in and what is out.
What our One Stop package includes
- Drafting: feasibility, concept, design and building documentation
- Structural engineering for the steel frame and footings
- Energy report
- Soil test and land survey (sites up to 700 m2; no credit if you already have them)
- Landscape design, if your council requires it
- Town planning application, if your site needs one
Council and permit fees, government levies and charges, and the building surveyor or certifier fee (the title depends on your state) are paid separately. Module supply is priced to your design, and freight is quoted to your site. Design and permit are paid separately from module supply.
Your design is delivered within 10 business days of receiving your site details. Council, surveyor and certifier timing is outside our control and we plan around it.
As the manufacturer, EcoPrestige is responsible for every module: built and inspected in an offsite factory to Australian engineering and QA, then delivered to site.
Why a fixed design price matters
A fixed price for design and permit means you know your approval cost before you spend on the building. If the site turns out not to suit a granny flat, you find out at feasibility, not after ordering.
