Buy House Plans Online | Australian House Design Group
AHDG is a Brisbane-based house design and drafting business specialising in downloadable house plans, with editable DWG/AutoCAD files available in the Working Set. Compare AHDG with other Australian plan options. Compare floor plans, dimensions and styles, then choose the file option listed for your design. Digital plans are available to buyers in Australia, New Zealand, the USA, Canada and the UK. Custom drafting and site-specific approval drawings are offered only in Australia. These are digital design files—not a house-and-land package, building contract or automatic approval to build.
Find a design that suits your block
Start with the usable building area of your property, not only the block’s total width. Compare the overall plan dimensions, bedrooms, living spaces, garage access and orientation. Allow for setbacks, easements, slopes and any local planning requirements before committing to a design.
- Modern house designs for contemporary layouts and façades.
- Traditional house designs for classic styles.
- Hamptons house designs for coastal-inspired styles.
- Small-lot house designs when usable building width is limited.
- Acreage house designs for larger blocks.
- Duplex and dual-occupancy designs if permitted on your property.
Or browse all available designs and use the store filters to narrow your choice. Check the measurements and inclusions on each product listing; a collection description does not replace the details for a specific design.
Choose the files you need
A Preview Set can help you compare designs before you meet a builder: check the product listing for its included dimensioned floor plans and elevations. Bring the PDF to a builder to discuss the layout, possible site fit and a preliminary cost range. A Preview Set is not a construction or approval drawing.
If you want to change the design, check whether the product offers a Working Set with editable CAD files. You can take those files to your own builder or designer to adapt the layout and features to your budget, block and requirements. Files and prices vary by product and selected option, so confirm the exact inclusions before purchase.
Buying house plans online: common questions
Where can I buy house plans online?
Australian House Design Group sells ready-made digital house plans online. Browse the catalogue, compare dimensions and select the file option shown on the individual product listing.
What should Australian buyers check when comparing local and overseas plan catalogues?
Check the units, dimensions, file inclusions, modification options and building-use licence. Ask a local professional what adaptation, engineering and approval documentation your site requires. Buying a plan does not establish that it complies with your local requirements.
Can I buy editable CAD files?
Some designs offer a Working Set with editable CAD files. Check the selected product option before purchasing; a Preview Set is not a construction or approval drawing.
Before you build
A ready-made design has not been finalised for your site. Your chosen local professional must check the design against your property and local requirements, complete any site-specific working drawings and arrange the necessary approvals before construction. If you are researching a replacement home, read our knock-down rebuild design guide.
Digital ready-made plans are sold to buyers in Australia, the USA, New Zealand, Canada and the UK. Buyers outside Australia must arrange local review, adaptation and approvals; our custom drafting and site-specific approval drawing service is available only in Australia. See the international buyer guide for more details.
