We're going to redecorate...the entire house.

Well, so we've lived here three years in March. It was always alright though and we've not done anything really with it - apart from fill it full of junk, of course - and we've worked out now that we want to change pretty much everything.
The boiler is 25 years old and has never been serviced, and we can't have hot water on without also having the heating on, and vice versa. Yes, our bills are lovely, thanks. In summer, we *really* need the ceiling fan.
The doors / windows / double glazing are nice - wide bay window at front, patio doors at back, SO much light in our through room, and when we park on the front we can see the trees in our back garden through the windows - for some reason I like this. It's also dark wood and leaded and I think it quite pleasing to the eye. It's rarely been weather treated though, is gappy and drafty, and front and back doors both stick in the damp weather, so it needs some work too.
The porch roof tiles are slipping and the gutters front and back leak something terrible when it rains (sorry mr postman).
The front of the house is ORANGE AND YELLOW. Yes.

Hallway! decent size but the wooden panelling below the dado rail is getting tatty, the wallpaper above the dado rail is *awful* (looks like nicotine stained pattern but I *think* it's intentional) and above the picture rail is textured artexing - a different one to the ceiling artex, and both of them clash with the pattern on the wallpaper.
Open-plan living/dining room has BUSY (but lovely) wallpaper all over it - TOO busy - as well as a crazy-paved fireplace and hearth surround, oh and the archway between the two rooms has a stone edging too. They've GOT to go. Once it does, we'll also have to replace the floor throughout as it's been cut (wooden floorboard style laminate) to fit the 'paving'. Alcoves either side of the fireplace - one is the boy's 'toy store' and other is tv / xbox area. Dining room has huge display/storage units to ceiling, my cluttered computer desk / yarn store area and a huge dining table that seats 6-8. This is rarely used for more than us three because...
Kitchen! - tiny, galley kitchen. Can't fit two in at once. Not much workspace, even less cupboard space, curruntly also boasts boiler cupboard. Old oven that doesn't really work, though the hob is okay. New! Washing machine and dishwasher since we moved in and new-to-us fridge freezer as well (which meant having to lose a couple more cupboards). Basically, one cupboard for cups & glasses and a so-called 'useful' drawer, one double cupboard for plates bowls pans etc, one double cupboard for foodstuffs, one narrow cupboard for baking supplies & spices and one end cupboard for storage of bulk & spares ie unopened rice & pasta, oats, dried milk etc.
Upstairs - one tiny bathroom, door opens onto the loo, sink nect to loo, bath next to that, one shelf underneath window, built in cupboard under sink is not enough space to store spare toothpaste AND shampoo let alone towels, mouthwash, medicines, soaps, bath products etc. Quite nice (balck laminate floor, white tiles, reasonably newish) but no storage at all so everything has to be out and clutters the room up to look even tinier.
Our room - smaller of the two double bedrooms but is out back - trees and foxes rather than cars and buildings ;). Opens to entire wall of mirrored wardrobes. Ugly mirrored wardrobes, too. Only storage in house but eesh. Also have bed (nice black iron look bedstead, bought with employees discount when I worked for a bed manufacturer), one ottoman / blanket box (dark wood, old neighbours antique-ish, needs a polish) and one chest of drawers which we bought when Isaac was a baby as a shelf on it folds out to a changing table - very clever AND a nice looking peice of furniture. Oh and two rubbish bedside cabinets. We have to edge around sideways to get anywhere. The above-dado rail wallpaper is awful and old-lady ish. The below-dado rail wallpaper is even worse Both clash with the awful curtains. They all manage to go really badly with the horrible carpet.
'SPARE' room - sometimes called Daddys room, sometimes called Isaacs playroom, this is full of toys, cds, bookcases, 7 guitars, assorted demi-johns full of wine, empty wine bottles, and boxes. Once in a blue moon, these things at least partially fit inside the wall full of mirrored wardrobes in here, but most of that is taken up with amps and guitars and so on. I've been informed this room has both carpet and curtains, and that they are both horrid.
Isaacs room - has a bed, a cubey-drawer unit, a clothes rail, and a bookshelf/blanket box area. Is about 3 steps long and one wide. Wallpaper has been torn off and scribbled on. Posters (dr Who, pokemon, dinosaurs etc) try to hide this fact. Bed - was COT, now converted - has not lasted 5 years - broken slats all over the place. Curtains are fine, but curtain rail is hanging off the wall.

It's going to take a lot of work, and I don't know where to start!
