Is there some free software or an app for playing with designs for a house extension?

I'm fairly sure someone on here once linked to some free software or an app to allow you to play around with different ideas and layouts for renovations. Does this ring a bell with anyone?

I guess I want something like the Ikea kitchen planner but for the whole house. And a bit less crap.

You could try sketchup? It's really easy to use & has good tutorials. You can get a free version which will be more than sufficient.

Another vote here for sketchup however type " free house extension design software " into google and you will find quite a few offers.

Architects have to study and train for 7 years to even begin our careers so a few hours with some free software and a screen print will not provide you with a design but merely a picture of what you would like to achieve.

Thanks both. And we will definitely be using an architect! FIL is a retired architect so he would never forgive us if we botched this up!

We are still at least a year away from doing it, so the software is more just to play with various ideas before we throw it over to an architect. Also a bit of a reality check for the brief, when I force myself to come to the conclusion that no, the available space will not accommodate the massive kitchen diner, playroom, formal dining, utility room, study, and library of my fantasies.
