Costs of house improvements

[LIZS]

Seen a house which in some ways is ideal and keenly priced (motorway noise and want a quick sale ) but would have following maintenance issues which will obviously cost money long term. Has anyone got any experience of costs which may be involved to :

Run power from house to detached garage - about 20m away - to give lighting for parking area and security lighting. (Rural location so don't fancy coming home to park in dark)
Similarly run water supply to garden.
Maintain a mature large garden - about 1/6 acre is densely wooded, rest grass/rockery. Employ someone to do it regularly or a twice yearly blitz ?
Change area of flat roof - about 6*12ft - to slated sloping roof.
Do wood casement windows cost a lot more to replace than regular ones?

Not had a period property so finding the prospect a bit daunting ! tia

The electrics are not too expensive I would think about 1500. They will have to dig up and bury the conduit(?)which protects the pipes.What sort of water supply to garden?A simple tap is also quite cheap.Definitely employ someone regularly and local for garden
Flat roof I had one done 3mx3m 4 yrs ago and that was about 4k.
The wooden windows are about triple the cost of upvc but look miles better.You can however double glaze them if it isn't a conservation area and some window companies have more choice of frames which look ok in period properties or try getting a local good carpenter to look at them with a view to restoring and weatherproofing We are having a quote for this monday so will let you know

Thanks for that- v helpful. Noticed that the patio doors are particularly bad, rotting away at the bottom and there is a mismatch of aluminimum glass panels where they extended (hence the flat roof !) so they'd have to go. It is already secondary glazed for the most part.

There is also a lean-to affair used as a utility room. They've enclosed an area between the original outer wall of the kitchen and a brick wall facing the road but used corregated plastic for the roof panels. Leaks onto the electrics below would worry me and wonder if it even meets buildings regs !

Decent upvc looks better and more energy efficient than original windows plus secondary glazing.Get a really good survey done and then put in a cheeky offer!I am renovating atm and its great fun-sometimes!

"Decent upvc looks better and more energy efficient than original windows plus secondary glazing."

I'd be wary of putting upvc onto a period property.

SD I would never do it either prefer to freeze and rattle away and try to preserve them but new period bespoke windows plus secondary glazing would cost squillions plus lots of noise and dirt from motorway

Next door seem to have done and it doesn't look right .

Is there such thing as "decent upvc"?

There is a period house near me that has grey upvc and it looks quite good NOT as good as replacement wooden but better than chunky white.And is eco friendly too
