I do not enjoy maths, I have a lot of trouble holding numbers in my head and I get lost in the operations needed to manipulate them. However, I came close to having to do some maths today in order to figure out what degree of slope the house site has, luckily, I was saved by the internet. Why did I need this measurement? Well… apparently, having the degree of slope of the house site will make our house plans a whole lot more accurate and allow the plans to actually work on our site when we come to building. I just hope we did it right.
First I looked for what measurements I would need. Vague memories of Pythagorean theorem and hypotenuse floated through my brain along with the phrase ‘rise over run’ but with no real understanding of any of it; I didn’t know where to start. Enter the first clue; an explanation of triangle calculations on To-calculate.com.
I visualised a right angle triangle and used the handy little calculator on the site to do the hard work for me. The only measurements I needed were the length from the bottom point of the slope to the top point and the height needed to make a right angle triangle above that. The post at the corner of the chook pen was exactly at the bottom of the slope and a convenient large grey gum tree provided a marker at the top of the slope.
With some help from my partner (reluctant, but biddable enough) we strung a chalk line string between the grey gum and the chook pen post (my partner did the vast majority of the work while I provided constructive criticism) and hung a little level thingy off it. The end on the grey gum was weighted to the ground while the end on the post was pushed higher and higher up the post until the level told us it was now forming a right angle with the chook pen post as the short leg (rise).
After I had measured from the ground to the pink chalk line on the chook pen post and the distance between the chook pen post and the handy grey gum, I took these measurements in to my trusty computer. I entered the measurements into the calculator on the web site above and it gave me the degree and percentage of slope.
I dutifully (and hopefully) emailed these details off to Curvatecture (our partners in building) and waited to see what else there is to do.
I am also in the process of filling out a fire safety assessment and have the BASIX ready to roll when I get a copy of the plans. The DA is about halfway done and the On Site Sewage Management application is being filled out as we speak. Such a lot of paperwork to build a little mud hut in the bush.

I don’t do maths. It doesn’t like me. Or those little balancey straight line thingees. I’m more of a step it out, ‘eye-o-meter’ girl 🙂
You did awesome!! 😉 And that is a lot of paperwork and fiddling around to build alright.
Yes it is a lot of fiddling around. I don’t do maths either really, but the council and engineer needed it.
Bloody pen pushers 😉
