Hi! We're remortgaging our house in 2-months and we're looking to see if we can afford to get a bedroom extension done on the side of our house.

The house is a 3-bed semi-detached, it's already been extended to the rear of the property and on the side of the house is a utility room where the boiler lives, etc. There's also an existing chimney which is no longer in use. We're based in East Yorkshire.

There are 2 bedrooms at the rear, the one we want to extend is what you'd call a box room, it's really small. To extend the bedroom on top of the utility room, what do you think it would cost? I know it's a lot of guesswork, but we don't really have enough money in our savings to get an architect in etc. to do their job only to tell us it'll cost too much for us.

A colleague at work estimated around £25-30k for everything.

I've done some quick measurements, it's basically a 3m x 3m room extension. We'd be happy with a simple flat roof.

If anyone can provide us with some advice and estimates, we'd greatly appreciate it. Thanks.

A few years ago we bought our house which is in a tiny village where there’s no gas lines.

Our oil tank looks very dated and we’ve finally removed the shed that was next to it to get a proper look at it.

There’s no cracks etc, it appears to be ok but it does look very old.

Based on the attached images, does it need replacing now or can we hold off for a few years? We’ve no idea when it was installed.
