I'm planning an outdoor kitchen.

This will be a simple brick sided bench about 3 metres long and maybe 800 mm deep.

I'm going to build it on a slab to support the weight and ensure a level surface.

As one end of the bench will butt onto the side of my house, I was wondering if there are reasons for or against leaving a gap between the new slab and the house's one.

I would like to not have a gap in the brickwork so as not to leave sanctuary for spiders and other creatures (I live in Australia).

You definitely want to leave an expansion gap. However, you can fill the seam using a flexible material. Foam rod covered with a seam filler, is one common solution. There are also products sold that can simply be pushed into the seam.

Check your local hardware/home improvement store, to see what's available in your area.

  • So - that gap is between both the slabs and the bricks?

    Yes. A gap between the two slabs, and a gap between the house and the bricks. You want everything to be able to move, without pushing anything else out of whack.
