My garden slopes downhill away from my house.

I want to build a block shed at the bottom of my garden. It will be about 4m x 5m and will go up to the fence on both sides.

I've looked on the planning portal website and it mentions that any outbuilding within 2m of the boundary must have a maximum height of 2.5m.

As its on a downhill slope does the rear have a maximum height allowance of 2.5m as well?

Thanks Freddy

So having max height of 2.5 m at front and 3.3m at rear will be ok?
Quote from the technical guidance (page 41)

If any part of the building, container or enclosure is within two metres of the boundary of the area around then house, then the height limit for the whole development is restricted to 2.5 metres if it is to be permitted development.

Sorry, I'm being thick so bear with me please.

I understand that it's 2.5m max height from highest ground so in my case I'm building on a downhill slope. The front will be 2.5m high and as long as I keep a flat roof will I be ok as the rear wall would be more than 2.5m high as it's starting from lower down?
