Help with new room!

Basically a mezzanine area, easy between to walls.

What size is the room.

 

Hi

Are these the measurements of the room or the structure you want to build? The 205 cm is low for a ceiling and if you have a standard height ish ceiling 240 cm you won't have enough room on top to sit up.

 

Don't worry so easy to do 204 instead of 240 - why do you think the majority of us on here will have a large collection of "off cuts"

 

Mr Jones, the simplest way to do this - certainly the way I think I'd tackle it (and I always go for simple...) is a timber frame clad with MDF. That way you'll have a good and durable surface finish ready for the paint of your choice.

The frame can be made from CLS, either 3x2 - or 4x2 if you feel you must. The beams for the bed, however, should be 6x2's I reckon.

What further info do you need?

 

You don't say what your existing wall construction is but if you could move the door you might be able to have a cabin bed with a wardrobe underneath and the work table and still have full height by the door, photos of existing room would help.

 

Here's crude...

Knock it all up using nice clean CLS, 3x2 will be fine. The only exception is the bed frame - that'll need to be strong against bending so I'd suggest 6x2 there.

The rest is basic assembly - just use screws, but pre-drill holes. For the desk, screw the two horizontals to the sides of the uprights and also glue them (PVA) 'cos they'll have to take a fair amount of downforce.

Once it's all built, you'll then need to clad it all in something suitable. If you want a smooth finish ready for painting, then MDF is the obvious choice, I reckon, 'cos it's a structural material in its own right. It'll need a lot of cutting and trimming tho'.

Just butt-joint the MDF - overlap them in external corners - which will mean a smooth surface meeting a rough cut end. You can smooth down that end to match the smooth surfaces using sandpaper, but the ends will still be more rough as it's 'end grain'. However, a couple of thick coats of water-based primer (or even matt emulsion paint) followed by finer-grade sanding will have it blending in.

The bed panel will need to be stronger, tho' - I dunno - 18mm ply or chipboard (eg - flooring panels).

This is a nice project, but will take longer than you think and be more work than you may imagine. The cutting of the MDF sheets to size will be the most challenging, so you'll need some good hand saws with sharp, fine-toothed blades.

If you use a jig saw and the edges, when butted together, have lots of ragged edges and gaps, don't worry - just run a bead of decorator's filler in there. Make sure it's stuff that will withstand some movement and can be sanded down.

I often use solvent-free adhesive for this (no-nails type stuff) and use it to not only glue the panels together, but also act as a filler - ie run a good bead, fix panels in place (30mm panel pins will do), and then wipe away the excess adhesive with a damp cloth - this should leave a neat join.
