ceiling height

uxak

we have just joisted the house last week and ceiling looks to be a bit low to us even it is right size with the plans which is 2.5 meters. but when we put screed and slabs to it we will loose more height.
probably a stupid question but is there any way of adding another block to the walls without disturbing joists?
or any ideas?
thanks

what do you mean "when we add the screed"....

are you pouring a finishing screed over an already poured floor slab??

do you have the option of using the floor slab as your finished floor..... level and powerfloat......

why didnt the blocklayer know / allow for this??

the slabbing is only 1/2 inch so that will make little difference.

Uxax,


Just a word of warning min. ceiling heights for a room in a dwelling is 2.4m (can be lower for bay window ceilings).

Your architect / engineer might be reluctant signing that off.

I assume, your screed will be approx 50-75mm, if so you should still be over the 2.4m.

assuming a 75mm screed, to bury rad pipes... and a 20mm floor covering... and a 12.5mm plasterboard ceiling with skim finish....

you could very easily end up below 2.4.

Plus, it feels terribly crouched and prohibitive in a large room.

you wont be able to hang drop lights as they will become a hazard of hitting your head against, so you may be restricted to spots, tubes, downlighters or wall hung fittings.

is there any way you can still use your floor slab, even if it means chasing the rad pipes....

As stated above, 2.4m is the recommended minimum ceiling height.
It is the average height in most homes (98% of housing estates) in Ireland. I wouldn't worry about light fittings - standard will be fine.

Ceiling heights always look low during construction.
IMO you won't appreciate room dimensions or ceiling heights until slabbing & plastering is complete.

Q. Is there any way of adding another block to the walls without disturbing joists?
A. No, not without removing the joists.

2.5m is on the drawings - so technically its too late to change now as increased height will affect your planning permission. IMO This is really a design issue which should have been decided at the design stage.

Can you do without the screen or use a 50mm screen?
Talk to your Certifier (Arch. Technician, Architect, Engineer) as they will be familiar with the design and works on site.

thanks for the replies lads.
at the moment from concrete slab to the joists it is 2.5meters. i think we will definetly be over 2.4 meters even if we put 2 inch screed finish to the floor.
i am meeting the engineer tomorrow so i will have a better idea. as suggested i might use the concrete slab as my finished floor to gain a few inches. maybe levelling compound might do the job. any ideas how thick this compound should be?

thanks again.
