welcome to onplan

onplan design and drafting is a residential design and drafting company whose clients include both owners and builders. We offer our services generally to new houses, extensions and renovations, and various minor works. We do not have a preferred “look”. We prefer to adapt your thoughts and ideas onto paper, creating a unique home in floor plan and street appeal. Our design and drafting takes into consideration your requirements, the attributes of your site and surroundings. From this we are able to interpret this and come up with creative design ideas which remain practical and aesthetically appealing.

We have a comprehensive knowledge of the building industry, therefore an acute awareness of what constitutes quality plans. Our plans are drawn to include content and details most often missed by other residential design and drafting companies. We know how to build houses, and in turn, design with this knowledge. We provide plans so builders know each of their trades are well informed, and in the case of concreters, plumbers, carpenters and roofers, are all following specific set outs for their work. If there is a trade involved in the project which requires specific set outs, such as the tiler or the cabinetmaker, we can also provide this specific detail.

We use revit software exclusively, which allows for the most dynamic presentation of concepts and preliminaries giving the client the opportunity for considered changes throughout the design process, and a total understanding of the actual design as it evolves.

We can also offer addition assistance in developing a specification (rates apply). Along with the plans and structural engineering plans, a specification is the document which describes every particular item and/or the quantities required, or even the pc or ps sum to allow. Prime cost (pc) items are fixtures and fittings that the owner is to select after the contract is signed, and provisional sum (ps) items are work included in the quote, which the builder cannot give an exact price for. Both pc and ps items shall have an allowance stated. A specification is essential when tendering out the new house or extension and renovation to several builders so as the quotes are able to be regarded as “apples for apples”. 

Please feel free to contact us to discuss your design drafting requirements.
