​free application submission

​​Some architectural practices leave you to submit your own applications. However, we think it's very important that we submit your application so that we are able to keep abreast with any revision requests from the planning officer.


We also actively seek their advice with regards to any amendments that may be required to approve your design. We have found that this streamlined and improved our success rate.

​Free ​Design revisions

​​We don't take the design of your extension likely. This is why we incorporate free design revisions as standard.


We understand that you may need a few design iterations in order to realize a design finding storage spaces working out the design flow altering window and door arrangements to maximise light changing fixtures such as Islands in kitchens, door swings stair orientation are b​ut to name a few of the things that you may request revisions on.
