Painting,tile,make ready etc.

Everyone I talk to has gone over budget which makes me want to downscale my plans. However that seems to defeat the object…

I want to build a timber framed house approx 1700sq ft 4 bed 2 bath with brick and tile finish.

I already have the land…My partner and I can do a lot of the painting / tiling and labour work so we can save a bit of cash.

Is £100,000 maximum realistic for the North of England including all major works, kitchen and bathroom fittings?

Or do I shelve the project?

I’m interested in buying small (no bigger than 2×2 inches) tiles to use to make mosaics. The big-box hardware stores have been disappointing selection-wise and art store mosaic tiles are very expensive, so I’m looking for an affordable option. Saw an ad in the paper for Buddy’s and am wondering if they have small tile (like what is used on bathroom floors) in multiple colors at reasonable prices, and if they are even open to the public or just to contractors. Any information on this particulate store or other options would be most appreciated. Thanks!
