How much would this balcony cost (approximately)?

[dominoman]

I would like to create a balcony / patio so that I can sit outside the kitchen and then take a few steps down to the garden.

It's to replace where the steps are in this photo:


Everyone I've asked says just build some raised decking. But I would prefer it to be done in proper rendered blockwork.

How much would it cost, very roughly, to build a rendered blockwork raised area of around 2m x 3m, with steps down? Ideally it would also have some storage space underneath.

Is it complicated?

Thanks for any advice

you will need planning permission as its higher than 300mm
theres a fair chance you wont get permission

Oh no! I hadnt even thought of that.

Next door has a raised patio already, built three years ago. So if they got permission I guess I would too? Or perhaps they never even asked.

Now I dont know what I should do
