Thanks for the replies. I was originally thinking timber wouldn’t make a good permanent solution due to the potential for movement/ the need for airflow. But would avoid issues with too much weight on the screed- last thing I want is for it to crack! Anyone got other construction ideas? Or anyone else think the weight from blocks will be fine??

Thanks for the responses. I had assumed timber wouldn’t be a good option because I’m laying stone flags on top and the potential for movement, and temperature changes from the underfloor heating? @JamesP if you rebuild with block how would you go about that? Would you make it solid? I’m not sure if the weight would be problematic on top of my screed

Hi, I’m looking for some recommendations on the best method for building some steps between two levels in a walkway inside my house. The two levels have a 78cm differential and are both hard surfaced (approx 50mm screed with underfloor heating pipes). I’ll align with the regs and have 4/5 steps with appropriate tread and riser dimensions. And I’ll be finishing the floor and steps with c20mm limestone flagstones so that it all ties together. My question is what do I build the step construction out of? Do I build the steps to be solid blocks/bricks? Or is that too much weight on the 50mm screed? Or just wasteful? Or is it better to create a skeleton of blocks and lay concrete boards or similar across to from the base for the treads? Will that be strong enough? And if so, any tips on the spacing between blocks and thickness of boards? Any advice would be gratefully received. Ignore the row of bricks at the top level of my picture- those were just to retain the screed pour and will be removed. You can see the UFH pipes running between the two levels. Thanks
