Thanks active builders, I thought 1.8m depth for the wet area - assuming bath is 80cm wide that leaves 1m depth for the showering area, but then that only leaves 1.2m to fit basin and toilet, which I thought might be a bit tight? We don’t really want a small basin as this is the main bathroom. My other option is to have toilet and washbasin opposite each other in the 1.2m run, but then this leaves a 80cm gap between toilet and washbasin and not sure if this would look a bit cramped?

On Aliexpress the diameter given is of the overall diameter, here is a deep tone chime set on their site; https://www.aliexpress.com/item/33inch-Hanging-Wind-Chime-Large-Deep-Tone-Resonant-Wind-Chimes-Church-Bell-Outdoor-Garden-Yard-Home/32975926622.html?spm=2114.search0104.3.29.4c3c26462ghPcr&ws_ab_test=searchweb0_0,searchweb201602_10_10065_10068_10547_319_10891_317_10548_10696_10084_453_454_10083_10618_10307_10820_10821_10301_10303_537_536_10902_10059_10884_10887_321_322_10103,searchweb201603_6,ppcSwitch_0amp;algo_expid=e37168ed-1610-4a32-ab42-8738116496b1-4&algo_pvid=e37168ed-1610-4a32-ab42-8738116496b1 Excuse the huge link.

Miriam Do you actually mean columns as in structural elements or do you mean decorative pilasters? The size of a column is dependant on the load it is carrying and if these are load bearing elements. I would consult an architect and an engineer. There are standard sizes but the choice is driven by the structural requirements. If they are pilasters. Then a starting point would be to talk to suppliers of the plaster replica's https://www.lassco.co.uk/a-pair-of-english-cast-plaster-pilasters or others. They should be able to give you some guidance on the choice and size modules. Hope this helps Best David

rinq good point. Here is what we have so far. Some notes: - The rest of the plan has changed slightly so I don't want to waste people's time commenting on that. I will upload our final draft in a new post when we have it for feedback on the whole plan. - The main room in question has had 1m added along the horizontal to make it 8.90m long. - We have decided we want to swap the kitchen and dining rooms. - The front door has also been removed from that back wall (the bottom of the plan) so that back wall is now doorless. The front door is now located where the word "screenshot" is conveniently located. :D Ellie good questions. The house is being designed now. The architects have suggested a room this size based on feedback we gave them. Now we have it drawn up we don't love it. For example, I hate having the back of the sofa in the way of the hallway there. I think that is terrible design. It all looks cramped to me. There are 3 of us in this home. In the plan above you can see a rectangle in the top right with the lines across it. That is a closed in porch/veranda so there is some living space there too. Otherwise, this is it. minipie thanks very much. It's good to know it works for you and yours. I've added the proposed zoning above and wondered if that resembled yours in any way?
