Your home is the most important piece of architecture you’ll ever experience. It’s where you spend most of your life. It’s where you express who you really are. It’s where you feel most yourself. This is somebody’s home. It’s also a work of art.

This is the Lost House hidden away in London’s King’s Cross and designed by the much feted British architect David Adjaye, the poster boy for sexy, up-market housing. He creates spaces that seduce by fusing a relationship between indirect light, materials and colour. This iconic house is almost totally black. Black resin floor, black walls, with no windows, but three light wells.

This is the kind of home we all drool over in the glossy magazines, but you could argue that it’s spaces like this that have driven our national obsession with what a home looks like and how expensive it is. Not what it feels like, or whether it’s good for us. Does it feel like a home, or does it feel like an artwork?

Suzanna Wallgren

Yeah, I think it feels very much like a home. I don’t mind at all to be in a piece of art.

Tom Dyckhoff

So then does the house rule your life?

Suzanna Wallgren

Yes, in a way, yeah. You cannot leave things out. They will disturb the feeling of the house.

Tom Dyckhoff

So what are the demands that the house makes on you?

Suzanna Wallgren

You have to have a certain upkeep. You have to polish the floors. You have to keep it tidy. You have to work on the concrete. It definitely requires maintenance, absolutely.

Tom Dyckhoff

A lot of windows. A lot of window cleaning must go on here.

Suzanna Wallgren

You have to keep very good friends with the window cleaner.

Tom Dyckhoff

But even with all this glass everywhere, the one you can’t help noticing is a lack of direct light and a pervading gloom. It’s very dark, though, as well. I mean, all the blackness. You never feel like you’re living in a bunker? Or a coffin?

Suzanna Wallgren

No, I’ve heard many things, but not that. For some reason, I never felt that this is stark or very cold feel to it. It may not be for everyone. It probably is not for everyone, but for me it is, yeah, it’s very, very peaceful.

Tom Dyckhoff

This is a beautiful house, meticulously thought through. But I’d argue it’s a prime example of an architect as artist, making a house that rules you, instead of making a house that fulfils your needs.

Most of us don’t live in a work of art. We buy places like this. You thought the Lost House was dark? Unbelievably many windows in new housing are just over half a metre squared, about the size of a pizza box. Why so small? Simple. To save money. Small windows in new homes are a real concern for Professor Foster who, for more than 25 years, has studied how a low lux or light level can effect our internal body clock.

Prof Russell Foster

Outside light is incredibly bright. Even in a cloudy day in London, you’ve probably got 20,000, 30,000 lux. The equivalent in your home would be 200 to 300 lux. In fact, people have argued that we live our lives in dim-dark caves.

Tom Dyckhoff

This is where I live. A flat built in the 1950s. And the thing I love most of all about it, the big windows. But I’m curious to see what a lack of light does to me. So Professor Foster has devised an experiment, boarding up my windows for a week to the level of a house with the smallest national average window size.

Prof Russell Foster

So what we’re going to do is reduce the light probably to something like 50 or 100 lux. Still many people are living under those sort of relatively low light levels. And then see how you cope with that reduced light exposure after about a week.

Tom Dyckhoff

It sounds very depressing. Oh, my god, what have I let myself in for? I bought this flat for the light, and I’m going to be without it for a whole week. It feels like being in prison, and the door has just slammed shut. So this light meter will detect how much is coming in here before we put the boards up. OK, that was about 200 from this position in this room. Now it’s reading about 50.

I’ve got all these different tests to do. Urine sample, that I've got to keep in the fridge and in the freezer. Fridge full of urine – that’s very nice. Blood test, got my glucose monitor. This is my sleepiness scale. It shows you how sleepy I’m feeling throughout the day.

And then these ones. These are mood ratings. Do I feel calm? Do I feel sad? Horrified? Happy? Angry? Do I feel extremely angry? I feel a bit angry at the moment. I have to be honest. The whole flat feels a bit like it’s been plunged into depression.

I feel like I’m living in a cave. Or like in a Goth’s bedroom or something. I really want to get out now. I really feel like I want to escape. But you know the most worrying thing for me? The most worrying thing of all at the moment? It’s these, look, my plants. I’m not even allowed to leave my home for a week.

Day four, very glum and very tired. There’s this sort of gloom over the whole flat. It does smell like a gentleman’s toilet. I can’t really wait for it to end now, I think. It’s horrible. I hate it. Make it stop. Not long to go now. I feel really, really glum.

Isn’t that amazing? To reacquaint yourself with the Sun after a week. I feel like I’m going on holiday, like I’m off to Saint-Tropez after a spell in the Arctic North where there’s no light. Thank goodness that’s over with. But I wonder, what was all that darkness actually doing to my body?

Prof Russell Foster

So your tension and anxiety went up significantly.

Tom Dyckhoff

Wow.

Prof Russell Foster

Your depression and dejection went up really quite a lot, but look at this. Your vigour collapsed enormously.

Tom Dyckhoff

I know I felt glum, and a bit blue, and a bit grumpy and so on, but to actually see the swings.

Prof Russell Foster

Now let’s look at the glucose levels. And I have to say, I’m a little concerned. A glucose level above six is regarded as high. And what you see is that under the dim light conditions, your morning glucose has moved from 5.7 to 6.8.

Tom Dyckhoff

So I’m sort of borderline diabetic? That’s not good after a week, is it?

Prof Russell Foster

Certainly, if that was sustained, then you’d need to bring that down below six.

Tom Dyckhoff

Shocking, isn’t it?

Prof Russell Foster

It’s quite marked actually. What was really interesting, and that urine collection was worth doing, because these data are really fascinating. If you were perfectly entrained, the body clock was exactly locked on, the period of the peaks would be exactly 24 hours, but they’re not. In fact, we’ve got a period of 24.2, which is a little bit longer, which fits with the idea that the body clock is beginning to drift. Those peaks are getting a little bit later and later.

Tom Dyckhoff

Now what is the consequence of that?

Prof Russell Foster

Well, what you’re getting is a tendency for internal desynchronisation. The master clock in the brain is at a slightly different point to the clocks in the liver, to the ones in the gut.

Tom Dyckhoff

So if I was to carry on living like this, like many people do in new homes, what would be the result?

Prof Russell Foster

You’re more likely to be depressed.

Tom Dyckhoff

Blimey.

Prof Russell Foster

You are increasing your chances of immune suppression, metabolic abnormalities such as diabetes two. And, of course, all that is associated with increased levels of susceptibility to disease.

Tom Dyckhoff

That’s quite incredible, isn’t it. That’s quite an incredible reaction, response.

Prof Russell Foster

We are an extraordinary species, and perhaps just profoundly arrogant. We think we’re independent of so much. We can do what we like, when we like. And something as trivial as the amount of light we see each day is not considered as important.

Tom Dyckhoff

And yet it is. It’s fundamental.

Prof Russell Foster

It’s critical.

Tom Dyckhoff

I’m astonished by what a lack of light can do to us. Luckily for the house builders, most of us can get out for a top-up of natural light. But for those who can’t, and for all of us in winter, staying at home in a house with small windows can certainly damage your health. And it gets worse. It’s not just light they skimp on. This country is building some of the smallest homes in Western Europe, and it’s having a devastating effect.
