Brains and steps

maybe a solution would be to paint rocks on it? Joking of course.

Aren't modern metric bricks 65mm high ?. Two courses and two courses of mortar at about 10mm makes your 150mm. Three courses plus mortar = one course of blockwork (plus mortar)

Older bricks were a variety of sizes. Our local Barclays bank was built in about 1920 something and the bricks are much slimmer. The 1970's extension to the rear was done with modern metric bricks and the way they have jointed new with old is awful to look at.

Glue Artificial turf all over the patio and it will raise its level and then provide a soft landing for those that trip.:-)

AIUI it's a "raised platform" (same as decking) if it's over 0.3m high and then /not/ permitted development.

The photo and mention of a 'builder' suggests that modern bricks were used though, not reclaimed old victoriana !

It's about 220mm from the DPC to the patio. There's a step between the door and the patio. We didn't want the patio any higher or it would overlook the neighbours too much.

Thanks for taking the time to do that. Very kind. What package did you use to create the drawing?

What size bricks tho?

Indeed. We don't know how big the ops bricks are, nor where his dpc is, nor whether it is constant or stepped around the patio...

No probs - only took 10 - 15 mins

What package did you use to create the drawing?

Sketchup from Trimble - I still use the free 2017 "Make" version from the end of the Google era. That runs as a standalone application.

The current free version is web based. (not tried it to be fair - it might be ok)

I often use it when designing furniture or planning building projects.

e.g.:

Also for when you want to conceptualise stuff for explanation, rather than being used as plans as such:

For a web app, it's surprisingly good, but I think you can only save to their cloud and printing is a no-no.

All new 'common' bricks are the same size, though not the same finish, or classification (engineering bricks).

ever been to a builders merchant ?. All you will find is common 'standard' bricks, which is what that house or extension and patio is clearly built with.

Do you know if you can you round trip files with the desktop one?

(or even download from the web app for that matter?)

TBF, if starting again, it would probably be better to learn Fusion 360 since there is a "free for hobbyists" version of that.

So all new bricks are the same? Dear dear

You can download in .skp .dwg/dxf .png .stl .3ds plus several more formats

Looks like printing may have improved too, I'll try it to PDF with a proper scaled plan and see how it does now. I do have a paid sketchup licence but I don't think the import/export features of the web version are conditional on that?

Never been to a brick library then?

You are guessing & googling....

Limitations coming in from 1st October?
