The houses in the OP would be laughed at in America's Real Estate business. You would never be able to sell them. (For what they are "worth", that is.) The difference is actually quite surprising.

Florida (where I live) had some of the worst prices during our Housing Bubble. They were ridiculous, but still not anywhere near the atrocious prices of those houses, based on square feet and overall appearance/age.

Up North in the UK prices are cheaper, but finding work is near impossible. Down south where the work is, enjoy paying at least £350,000 for a 3 bed house. And don't expect that to be detached. Detached is really £450k +

Unsurprisingly, I'm looking to emigrate asap. 

That's much cheaper than anywhere in london

http://www.rightmove.co.uk/property-for-sale/property-38343928.html?showcase=true. This is an average sized house on the outskirts of London

http://www.rightmove.co.uk/property-for-sale/property-40552172.html~ this one is the same amount of area as the one you linked, but it costs much more!

Land is just incredibly valuable here, in London anyway

Housing in the UK is pretty poor and expensive, land is pretty precious. Housing is definitely one thing I love about the US.

Those prices are no joke. I bet I could easily drive with a truck through this house you posted. 450k ? This house can not be good. Even if you exclude paper thin walls, cheap basic materials, and sucky isolation. Whats the Interior made out of ? Legos ?

A house of that size has 4 kitchens ? 4 Bathrooms. 1 kitchen costs 50k. 1 Bathroom 25k. Does it have a basement ? What are the floors made of, are they heated ?  

Its a huge house but the material costs of our smaller house exceed its price, not even talking about land, location, furniture or the cost of the guys building it. Just bricks floors woodwork glass stones. 

it doesnt say it has four kitchens. from the pictures the house looks nice. It does have a basement. there are pictures and info in the link if you go to it. all of your questions are answered. Probably no heated floors, not very big in america.

Most American's would find UK houses small.  The average UK house are built in what is called "Cottage Style", with a living attic for the second floor.  Charming, to say the least, but it reduces the living spaces, primarily the bedrooms.

One modern house I looked at in the UK had 3 bedrooms, which is large, but that third bedroom was 8' by 10'.  You could fit a single bed, and a single upright dresser, with a wardrobe for hanging clothes.  Significantly smaller than a modern bedroom in a modern US 3 bedroom house, which happens to include a full-size closet for hanging clothes. 

Not to mention the bathrooms are extremely compact.  My bathroom in my house was as big as a friend's bedroom in her mother's house.  And then there's the refrigerator in the kitchen.  :/  Can we say tiny.  The average house in the UK has what would be considered an apartment sized refrigerator.

Finally, there is the amount of actual property you get when you buy a house.  The average lot in the US is between 1/4 to 1/2 acre.  With 1 and 2 acre lots being common.  If you're lucky, you have 10' or more between you and the street in the UK, and an ample back yard (garden).  But the space between you and your neighbors, especially on the sides, is often extremely tight.  On average, closer than in the US.   

Having said that...I think there are some fine examples or home architecture in the UK.  I've looked at several and thought they were outstanding.  Not to mention, the fact that there are still thatch roofs in the UK is awesome.  It'd be like finding a sod house here in the US, which you won't find. 

Thanks for the detailed reply :) 

That is something I always noticed how much larger the US fridge freezers and bathrooms are. Personally I think that having more space between you and your neighbours & the street is far healthier, mentally anyway, as it gives you more space between you and the rest of the world. 
Some of the architecture here though as you said is really quite good, but on the flip side I think interior design in the US can be better as there are more interior design firms. I saw one in NYC that specialise on PVC ceilings  and their designs were outstanding. 

That's one of the interesting aspects of UK home designs, I think.  Here, things like Terra-cotta tiles or slate tiles would be considered expensive options compared to asphalt shingles.  Or brick, stone, or stucco siding as opposed to vinyl lap siding.  The UK uses largely natural building materials, except for the interior, while in the US we use largely petroleum products for the exterior. 

Cement as a building material is also interesting.  Cement, though equal in price to the US, is used sparsely as a building material there.  Where as here in the US it's a fundamental component of every building.  I was surprised to see a brand new house being built in Scotland, up on a hill (above the water table) without a decent basement or even crawl space.  It was roughly a foot between the dirt and the bottom of the floor joists. 

Wood is something else that gets limited use there.  To find a house with any wood siding or trim requires that you take a trip far north into the Scottish highlands.  Otherwise the primary building supply is stone, brick, or stucco.

Another quirk of the UK is lead roofs and a whole industry build around it.  I don't know when lead went out of favor here for roofs here, or if it was ever in favor here, but tar is the predominant material for sealing roofs. 

We have quirky design considerations.  Space is one of them.  To spread out and to put stuff.  It was one of the problems with the Ford Mondeo when Ford brought it over to the US as the Ford Contour.  The Mondeo lacked cup holders, so Ford had to redesign the interior of the car with cup holders for American buyers. 

Hmm its extremly big but what worries me is the price. It can't be that cheap. I doubt it has the same buildquality as houses around here. Unless americans somehow get raw materials 10 times cheaper. The only way I can make sense of it is if the house is more like a movie prop and less like a house.
