Conservatory floor height and door sills advice

[Jakash]

Hey there's a similar thread about this from a decade ago but I wasn't clear on the answer.

I'm shortly to lay the concrete slab and then screed for my conservatory. Plan is to then her heated electric tiles on top. The access to the conservatory from the house are through two sets of upvc doors on my property which have upvc door sills outside

My question is what height do people normally build a conseravatory floor to.. is it the same height as the house or slightly lower? What do i do about the door sills, how to people normally handle this?? Do they cut them out or pour the concrete around them.

Builder suggests doing screed up to red line, bottom of the UPVC sill attached... But don't I need to leave a gap (green line, say) to prevent a 'step up' into the conservatory? Also tiling around the sills will surely be really tricky.

Any advice really appreciated!

Your floor inside is probably at the height of the pointing, the flooring of whatever type is then on top. So if you do the same you'll end up with the same height either side of the door.

Electric heated tiles are THE most expensive way of heating possible. A conservatory is THE most expensive room to heat. Both by a long shot.

Have you had a conservatory before? Many who have them hardly ever use them, too hot in summer and too cold in winter. You could spend more on an extension but have a much more valuable room.

Thank you. I suppose my question is more about what happens to the lip or sill on the doors then? Builder is saying the floorer / tiler will cut them off, but I don't know if that's going to be possible if he half submerges that uPVC lip with screed!

Yeah I've had a conservatory before and love it. Will also have heaters and AC but not expecting much use of it all thru deep winter and summer!

Forget the conservatory and build an extension.

Then you can have the floor running right through.

Thanks Andy. I'll put the brakes on the whole thing asap!

I took my coni down 8 years ago as it was south facing, too hot in summer and freezing in winter, even with a large radiator in there. Now have an extension with a vaulted roof.

If anyone actually wants a conservatory they're regularly available on online marketplaces for about £2. People desperate to get rid of them, buyer to dismantle and get rid of it so they can build a proper room in its place.

Although to be fair, a relative has one and does use it sometimes. It's a terraced house, the living room behind it would be depressingly dark if something more solid was put in its place. So they do have their uses.

But... their living room will be currently way too hot.
