extention ideas

I am thinking of building a 20 x 26 foot room off the kitchen , its going to have a stove and just a nice big space ,..

two ideas leave it a open celling with 45% pitch or have a room over it ..

i have a bed room 17 x 17 foot ,with a window upstairs that would make a door into the new space upstairs .. thinking a unsuite and walk in wardrobe for the area ..

any one know what area i would have upstairs with a 45% pitch many thanks

Lean too fully insulated roof with twin large veluxes over actual kitchen area,then normal roof/ceiling over dining area with new bathroom,ensuite and bedroom above.New bedroom above has high pitched fully insulated roof with twin veluxes aswell.

Also,If you go above ground floor,then you will need full planning permission aswell before you can build anything.

And Anything over 40 square meters needs full planning permission too,even if its only a single storey/ground floor extension.

Dont know,if you allready knew that,but you do now anyway.;)

Wind rarely acts as a downward pressure on pitched roofs, typically it imposes load in the form of uplift or suction. Roof straps are galvanised steel straps which tie the timbers to the wall, so that when an upward wind load is applied to the roof it prevents the roof from lifting off. (Typically it wont literally lift off, but you will get a nasty horizontal crack at wallplate level)...unless the wallplate is bolted as suggested above...which I doubt given that your blocks are 215mm high sugggesting that they're either 215mm hollow or 100mm solid...and I wouldnt bolt to either of them.

Typical roof strap detail below:

FesterBeatty, that picture has its own problems, I presume the 'grey T piece' on the right hand side of the picture is a door ope lining?
If this is the case then the lintel has no bearing over it, it is just resting on it...:p

FesterBeatty

I know - not one of mine, just pulled it off google images to show the strap. Maybe they're using load bearing window frames!!

It you look closely guys you see that they are using a pressed steel lintol at the course above. The "lintel" above the grey T appears to be a packing to fill a gap, prob from placing the lintol too high

That originally looked like a DPC to me, however it's a very sloppy detail.
