Hi Jan, As a few people have said the costs can vary wildly depending on your personal preferences and style! Its like asking someone how much a car costs... it depends on whether you choose a Fiat Punto or a Bentley but they will both clearly still get you from A to B :) Flooring for example you would be able to get a basic engineered wood floor or Luxury Vinyl tile for around £25 sq meter at the low end but for beautiful oil reclaimed herringbone pattern you could easily pay £200 sq meter. You will also need to allow for fitting on top of this. Again, depending on whereabouts in the country you are, £25-50 a sq meter are reasonable fitting costs. For a midrange wood floor I would expect to pay around £60 sq meter but this is very dependent on style. Herringbone is probably 20-25% more expensive to fit due to all the edge cutting. Skirting board I would take a look at skirting4u.com as if you know the sizes of your room it is very easy to calculate for costs. Wet underfloor heating can be expensive to install, especially as you would need to take up your existing floors (clearly no issue if you are taking it all up to replace anyway!) We paid £40 sq meter for our wet system and then £2000 to have it installed (50sq meter room) Decorators vary depending on the area but £20-30 per hour is fairly standard. You will need to account for prep work of a good painted so budget for twice as many days as you think it would take you to do it yourself. Electricians come in at around £200-250 per day plus materials. Get a quote or two for the works your thinking of getting done as our experience is it takes more days than you think! Sockets- think about what you'll do in each room. Where will you sit to use your laptop? Where might you like a lamp or two? Where will you use small kitchen appliances like toaster, kettle and mixer? Where will you charge your phone at night? Where will you plug in a desktop computer? Some of the gadgets you mention are nice to have if they are important to you personally but are unlikely to increase the value of your home when you come to sell it. Bathrooms are another significant spend and I would very roughly budget £5-8k for a midrange bathroom to kit it or and have it plumbed in. You would need building work on top of that to create your second room. These are all very approximate and again, hugely influenced by what type of specification / finish you want for the flat but may give you some ideas. Hope it helps!

Hello Sarah, If you have to keep the toilet where it is for soil pipe/ budget reasons, you probably already have the best layout with bath under window. Would you consider keeping the bathtub which does look lovely. Change your shower system to a boiler linked one and move your shower head to the ceiling (a waterfall shower). Re shower curtain, have a long flowing linen shower curtain made backed by thick plastic on the inside to protect from water, but looks beautiful on the outside. The pics you posted are elegant and easy to achieve...wood effect floor tiles, metro tiles on wall, some built in storage and nice towels. Maybe some colour through orchids? They thrive in bathrooms. Hope of some use!

I'd opt for unvented, you don't have the need for a large tank as the hot water is mains fed so its better than a conventional system, you don't usually have the old feed and expansion small tank in the attic anymore as the system is slightly pressurized in most systems now. Even with electric showers, i'd have the main bathroom fitted with a decent non-electric shower and with any kids showers i'd have the showers with thermostatic valves for safety. The downside to a combi as it only raises the water temperature verses flow so the colder the water is ie in winter, the slower/less pressure you can run the water, which is also one of the downsides to electric showers. There are a few combi's that have a small hot water cylinder in built but with 4 bathrooms to feed it would soon be used up. If you're worried about your existing pipework not being able to withstand any pressure then i'd get it checked now before any work is done instead of waiting for signs of water damage when all the work has been carried out.

hello, we would like to put a shower and sink in our bedroom but the nearest drain pipe is pitch fibre and has completed collapsed and we've been quoted £3k ish to replace it. Could we potentially use a greywater collection/treatment system and put it on our garden or, if sufficiently treated, put it down the rain water drain? thanks
