Thanks mate! I've been google searching some of the terms and if there are any i'll post them here. In the mean time i'm pulling out my hair with a few things!

1) what is the difference between a circular saw and a mitre saw?

Reading about them, they both seem to do the same job to me.....

The most important issue at hand right now is how i am calculating the amount of materials needed! I've calculated 5 times and each time i've come up with a different answer!! Ranging from 70 meters of shiplap to 167m!!!!

Ok i would want to build this project in 2 stages. The 1st being the kennel part and the second being the run.

Ok here's the picture again so you get the idea clearer:

Now the dimensions i will work in are going to be 1.2m wide x 1.2m deep and 1.6m high ( roughly 4ftx4ftx5ft) These are all external dimensions by the way.

Ok so 1st i want to work out how much shiplap i need.

I'll start with the front panel the one with the door fitted to it.

I'll make the door 60cm wide and then i've got 60cm that i need to panel up.

Ok so for the door i'll need it to be 1.6m high and 60cm wide. My shiplap is 125mm which will give me 111m when joined to the next piece. So i,ve said 600mm/111mm = 5.40 which means i roughly need 5.5 boards at 1.6m long each.

My shiplap comes in lenghts of 3.6m only so this means i'll get 2 boards of 1.6m from each length.

So i'll need a total of

3 lenghts that will give me my 5.5 boards with a bit to spare.

Next part is the bit thats next to the door.

The boards need to be 60cm long each. They need to cover a height of 1.6m.

So 1600mm/111mm=14.4 boards needed.

From each lenght of shiplap i should get 6 boards (3.6m/60cm)

So i'll get

3 lenghts that should give me 18 boards. The 3 spare boards are spare for mistakes..........

Next part is the back of the kennel.

Width is 1.2m wide and needs to cover a height of 1.6m

1600mm/111mm=14.4 boards

from each lenght i sholu get 3 boards (3.6/1.2=3)

So

5 lenghts needed that'll give me 15 boards.

I've used the same calculation for the other side panel opposite to the part with the door. So

another 5 lengths needed.

Now the part with the dog door.

I've decided to make the dog entrance 60cm wide by 60cm high.

So i need to cover a space of 60cm x 60cm.

So 600mm/111mm=5.40 boards

1 lenght needed 3.6m/0.6m=6 boards of 60cm each

The rest of the dog entrance section is 60cm high by 1.2 wide.

600mm/111mm=5.40 boards at 1.2m per board

1 lenght= 3 boards (3.6m/1.2m)

So

2 lengths needed giving 6 boards.

Ok on the roof i'll use 18mm OSB board and on the floor i'll use 18mm OSB aswell.

I HAVEN'T the slightest clue as to how many supporting posts i'll need for the kennel section but here's a go:

I assume you can say that to the kennel there are 4 sections to put together. So for each section i assume it will need 5 posts to it, 1 at the top,1 at the bottom,1 on each side and 1 in the middle of the 2 side posts. So 4 sections x 5 posts is 20 posts needed.

Am i right so far??
