Hello It's best to get the building company to do the lot otherwise you will have to project manage the whole rennovation and also find your own tradesmen. Some companies have their own tradesmen and others have self employed contractors that work for their company. As all the tradesmen work together all the time, the flow of the work will probably be much better than if you employed someone from each trade yourself. If there is an issue, the building company can resolve it quickly and probably at no extra cost if it was their fault e.g. if your electrician does all the wiring for the electrical points, then the next tradesmen maybe putting in the plasterboard ready for plastering but if he plasterboards over the electrical points without cutting out the holes out or marking where the sockets should be then you will have to ask the electrician to come and you may be charged for it as you are asking him to come out again to fix it. Another reason to go with the building company is because if you employ separate tradesmen, they will also have other jobs on the go, so you might be ready for the next stage but your plumber might not be free for another 2 weeks. When going with a company, they will do your rennovation as a project so they will organise and rotate the tradesmen for each project they have on their books. For kitchen fitter - it depends on what kitchen you go for, if it is a wickes, howdens type kitchen, the builder probably has a kitchen fitter that does these day in day out so would have no problem in fitting these to a good standard. If you are going with a more pricey kitchen eg. german true handless kitchen as an example, I would go with the kitchen fitter that is recommended by the kitchen company because they specialise in fitting these kitchens so would have a better finish. It might cost more but at least you will be happy with the end result. As they say, a kitchen fitter can make or break your kitchen. Some wise advice I received for sliding doors or bifold doors - always get the window company to install them as they will usually offer a 10 year guarantee and the Fensa certificate. That's what all the builders told me for my extension when I asked them for quotes, they said if a builder says they can fit bifolds, sliding doors - run a mile :-). Always go for a reputable company too and go and visit the shop to see the product. You can get cheap products on the internet but I heard the quality is not good and become faulty quickly. Good luck!

Hi Walt, The main difficulty with what you are trying to do is to make sure the new room has natural ventilation and light. Your house looks like a terrace house, which means there is potential in the loft (your budget permitting), where you could hopefully have a Bedroom and an En-Suite. You could potentially take some space off Bed 3 if you are struggling to get space for your new staircase going into the loft. Get a loft company to give you a price, they usually provide the whole service (including structural alterations, Building Control etc.) Alternatively, locate the store room in the centre of your house (back of the Garage where light and ventilation are problematic) and convert the front of the Garage into a habitable room. Can't comment on the location of the wet room but something could potentially go at the back of your Garage (on the Kitchen side of that wall), depending on how your foul water is arranged (I see you have a first floor bathroom so the SVP for it should begoing down through your Study and into the Garage, therefore possible) Good luck! :-)
