Fence on top of 6 ft concrete block wall

Hi there, greetings from Ireland. 1st time fencing and could do with some help.
Existing concrete block wall garden side (6') stone wall street side (approx. 30 feet long). For privacy reasons i need to extend wall upwards 4-5 ft. but with a fence (cedar if affordable) not more blocks.

Can i attach posts to wall only (and avoid having to sink them in ground)?

If so, do they need to be metal posts or will wood do?

What length post will be required to attach 5' fence to wall?

Many thanks.

Collis.

Collis,

Welcome to DoItYourself.com and the Fence forum.

You need to check with your local building authorities first. Here in the US, any fence over 6' high would have to be engineered. I'm guessing that about the same thing would apply in Ireland.

Metal outlives wood.

Grouting the posts (or sleeves for the posts) into the cores of the upper three block courses is preferable to face attachment with brackets (three brackets per post over five courses).

If unusual or high wind loading is a concern consider using six posts instead of five.
