Would definitely help in mocking up plans!

Hi I use a combination of 3 different programs depending on the need and who it is for. Each can be used to do complete drawings depending on your needs and time. I only use Sketchup to illustrate a 3d for clients so they have a visual. It has its limitations though as major changes can be quite laborious. I use Chief Architect only to nut out multiple layout options as you can simply click and drag to draw a wall that you have pre-defined the properties of eg brick veneer exterior, stud internal etc. If you have a room dimension you want to increase, you simply highlight the wall you want to move, click on the dimension that has popped up and change it. The surrounding walls alter to adapt to the new wall location so it is quick and easy. I don't use it for detail work as being an American program a lot of the options and specs don't apply unless you get Australian add ons... For detailed CAD drawings I use Autosketch 10 and TurboCad 20. Being old school (2D) I use Autosketch mostly for over 90% of my drawing as with about 7 or 8 tools you can pretty much draw anything and it does detailed construction drawings the way I prefer. Being only 2D you have to think 3D and draw the elevations etc in 2D but I enjoy that as it helps think through how something is going to be put together. Cheers

Oh super helpful. I searched for Pool Houses but "Enclosed Pool Houses" have really filtered the designs I was looking for inspiration. Thanks! It's so important I find the right builder for this in my area. I've not had much luck in the past with contractors and really want a smooth build. Cheers!

Sketchup is a good place to start as it is a free 3D modelling tool with a fast learning curve. However just because you can draw it in Sketchup, doesn't mean it can be built, it doesn't mean the building will be cost-effective, and it doesn't mean that it will comply with the regulations. Which is where design professionals come in. Just because I know how to use a spreadsheet doesn't make me an accountant. Best of luck, Dr Retro of Dr Retro House Calls/Dr Retro Virtual Visits.
