watersedge,

You might take a look at Turbo Floor Plan 3D, I used it to model a three story apartment building. The power of photography and 3-D CAD programming is awesome, you photograph the building exterior and interior for best color matching. and in the end you get a 3-Dimensional extruded building and photo realistic renderings.

Forget Autocad or any of the professional CAD programs unless you want to spend a couple of years learning how to use them. 3D only adds to the complexity. SketchUp is good for 3D shapes but not great for simple plans. You will want something you can use on a tablet so you can draw them up while you are at the house. To start, try some of the free House Planning Apps for whatever tablet you have. Look for one that lets you stretch and pull the plans or that come with a library of sample plans. There is not much variation in UK house layouts so once you have built up a small library of layouts you will be able to tweek the dimensions to suite many situations. Also get a laser tape so you can measure rooms on your own.

Microsoft Visio is easy to use.

My staff use Sketchup for many projects.
Unfortunately Auto Cad has gone to a subscription basis and it is not cheap even for the LT version. Even the LT version does way more than you would ever use, sort of like having a fast sports car and only driving it NYC, a waste. For what you do I would say Sketchup is a very easy to use and cheap way to do what you want and produces excellent results.
this was done mostly in Sketchup/Photoshop.
