Hi All (waves). I'm considerably out of my comfort zone here so please excuse my niaivity but I'm hoping someone can help.
We've recently had an extension and installed some trifold doors. My vision (having watched far too many episodes of Grand Designs ) was to have a fairly seamless floor from inside to out and we bought sufficient non-slip tiles to do this.
We are now in a position to proceed with getting the outside done but seem to be running into difficulties with the DPC and the "150mm rule". I have had a look at the "Workarounds" suggested and it would seem that the 'alternative dry area arrangement' would mean that the floor level would then be the same as inside. However I'm not sure what to do with the gap - we have children under 5 so the fall potential is high!
We are not doing this as a DIY option. We will get someone in (not the previous builder) but so far everyone we have approached wants to do the standard arrangement which would be a crushing compromise.
Any advice would be greatly appreciated. Thank you for reading.
the idea of the 150mm is to stop rain water bouncing up and bridging the damp, so you can go with a channel drain etc but if its only infront of the bi/tri fold doors then in the past we have just tanked under the runner and run the paving right upto the doors at floor level.

As GB has said it can only be raised to the door area. What have you chosen to lay on the patio area.
Are the Tri doors in pvc or hardwood on a rail system
If you send me a pm Sweet i would like to offer a quote because i'm not too far from you.
Thank you both for your quick replies. The trifold doors are wooden, on a rail system. The tiles are Atlas Concorde Extrema rectified porcelain tiles (already laid in the kitchen). The tiled area is directly outside the doors but the whole area actually goes round two sides of the house.
I am hoping that if I print your responses it will help potential contractors understand what we are trying to achieve! I think a slight drop in height is inevitable but it's just that 150mm below the DPC would be a big drop and not at all what I was hoping for.
