During my three week holiday I’ll be constructing a room and vestibule on our second floor. A new staircase, boiler and eventually a dormer will be fitted by contractors.
Occasionally I’ll be posting pictures of the progress on my Flickr account.
Oh, and being the nerd I am… I couldn’t get any of the free CAD programs to do what I wanted. So I wrote a simple application which I can use to script my building plan, in the most agile way possible 
This is the interface of the application:
On the left you can see the actual building plan (in scale) on the right you can see TextMate with the current script (groovy) loaded into it. The visual plan is updated automatically when the script file is changed. The application is still very rough, and the DSL I came up with is far to basic at the moment (lines and rectangles). But it works for me! Ow, and it has build-in printing support… without watermarks!
I’ll probably add polyline/polygon support this week, to draw in the electricity pipes…
That is just sick…
