H8GHOTI

My dad has built a house. It’s at the stage now where roof is on, windows & doors are in. He’s got a quote from the builder to complete the house to what I think would be called builders finish. Not moving in ready. No kitchen, no flooring etc.

The house is 2,300 sq ft. Downstairs has 2 living rooms, kitchen, utility room & bathroom. Upstairs 4 bedrooms, 1 en suite, and a bathroom.

What they have quoted for is below. Wondering what the min/max range or ball park figure for this work would be?

Stud partitions upstairs, red deal stairs . complete, window boards, red deal or shaker doors complete with frames, ironmongery, architraves and skirting.

I know the above is a bit vague with the details but that’s what he got from the builder. If it’s difficult to give a total price, how about costing for individual items listed? Would at least have some kind of estimate then.

With regards standard, everything would be average. He’s not going to go for anything expensive or fancy.
