Tucked away on stray backland plots and lost corners in desirable urban enclaves sit some of the most striking and original houses that you will never see. While the desire to build a tailored and bespoke home is increasing, the sites for translating these dream homes into reality have become increasingly rare. That's especially true of prime residential areas in London and other cities, where developers and eagle eyed buyers have already cherry picked most of the obvious and straight forward building plots. For those still determined to build a personal city retreat without being forced into the suburbs, this means tracking down one of those hidden away sites and then coming up with ideas for a pioneering house that will get round all the inevitable restrictions on space, height and light.

Architects and visionary clients have been busy proving that it is not only possible to build on these backstreet gems but that they can also produce a haven that is desirable, seductive and perfectly suited to modern urban living. One of the finest examples is the extraordinary home that artist Anish Kapoor and his wife Suzanne have created for themselves and their children in Chelsea, within the very heartland of desirable London real estate. Here Kapoor found a former antique showroom hidden away behind an Edwardian apartment building that gave him the chance to create a fresh family home, designed by architect Tony Fretton.

The Kapoor house is entered via a subdued entrance area on the ground floor of the period building before opening out into the newly built home that replaces the old showroom. It's a real surprise to see how the building unfolds with such a generous approach to space and light, despite the constrained nature of the house, which is tucked within this slim, long scrap of ground sandwiched between its neighbours. The heart of the house is a large open plan living room positioned between two courtyards, which help bring in plenty of natural light as well as providing outdoor space for the Kapoors and their two children. Maximising light and dealing with restrictions on the height of the new house – as well as managing a whole array of party wall agreements with the neighbours – created a design challenge that both Fretton and the Kapoors were more than willing to confront.

'There is a lot of trickery involved in the design to help introduce light,' says Fretton, whose practice was recently shortlisted for the Stirling Prize for his Fugslang Kunstmuseum art gallery project in Denmark. 'It was really impossible with that site to have a clear idea what was needed from the outset so we prepared a number of different options for the Kapoors. It wasn't easy but it does help to have a client like Anish who can deal with complex spatial problems. But then all private houses demand a certain level of ambition from the client.'

The final design of the house avoided the temptation for a large basement floor that would have been difficult to light, opting instead for two modest basements at either end of the house. The first floor was also limited to two bedrooms for the children, plus a large family room and study, so as to allow for the courtyards and roof lights that illuminate and enrich the main living spaces on the ground floor below. The master bedroom was positioned at the very rear of the site, again on the ground floor, looking out into the courtyard garden.

'This is the second time Susanne and I have built a house,' Kapoor has said, 'and I'd like to do it again. It's the most thrilling thing. We honed in on the fact that it was a difficult site and wanted to make something that had a quiet rigour. The lack of a façade is part of the challenge of the house but also part of its excitement. We made a decision when we first saw the site that something like a 20 metre long living room might be possible and that's something we decided not to give up on. We make it work and it works beautifully.'

The lack of a visible façade – which for many people helps define a house in the first place – is one of the unique aspects of these hidden backland houses. Tucked away on these slim sites between existing buildings, there is often no real opportunity for a striking public face to the house. These are buildings that tend to look inwards, sometimes arranged around courtyards or light wells. The power and design of the interior spaces becomes all important, with little or no outward wow factor, while the hidden nature of the sites offers a sense of calm and privacy. These are escapist spaces that cut themselves off, inevitably, from the commotion of the city beyond.

In Cambridge, architects Jeremy Ashworth and Emma Parkes were fortunate to find a small site for a house in the centre of the city. Their plot was a stray patch of ground that had been used for parking, tucked away behind high brick walls on a cul de sac, with access to the green parkland of Midsummer Common, as well as the River Cam, just at the end of the street. Knowing that their young children would have the benefit of the parkland so close by, Ashworth and Parkes were happy to grab the opportunity to take on the site and design a home that made use of every available square inch of space.

'We were very lucky to get the site because there are so few building plots in central Cambridge,' says Ashworth. 'They are very rare. But the site was a challenge and it became all about borrowing space and light where we could to make the rooms seem much bigger than they really are. We were not allowed to build higher than the eaves of the Victorian terrace house next door, which was quite limiting, so we took the main floor level down a little. We had to dig down and underpin all the existing walls around the site, but the extra height has made a huge difference.

'Access was another big issue. One afternoon I got a call at work and all the timber had arrived for the cladding but there was no-one on site. I had to rush over and offload all the timber and the lorry could only park at the top of the road so I had to carry it all down to the site.'

The entrance to the house is tucked away behind the brick walls that line the street, where a gateway leads to a small entry courtyard, which helps bring light into the house as well as providing a threshold. Ashworth's design creates an open plan and fluid layout for the ground floor, while maximizing sunlight with lightwells and a skylight over the stairs. A mini study is tucked away in a tiny alcove at the top of the stairway, while storage is maximised by inventive solutions such as cupboards hidden away under the floors. At the same time the house includes a number of eco friendly elements, including a green roof.

As well as issues of access, space, height and light, Ashworth also had to deal with building up against existing boundary walls shared with his neighbours. These are the kind of restrictions and limitations that now come as standard with these lost sites, which many bigger developers interested in fast turnaround projects don't find so appealing. But the fact is that any available city centre space - from garden plots siphoned off from existing homes to former warehouses to slices of backstreet scrubland - is now becoming like gold dust as both developers and those wanting to build their own homes hunt down any available sites. Ironically, as the impetus to design and create our own homes increases – encouraged by rising awareness of contemporary architecture and design – the plots becomes harder and harder to find.

'London especially is tragic in the sense that there is lots of money available to do things but not enough land to build houses on,' says Tony Fretton. 'It's shocking how little space there is in London for people with the desire to build their own homes and there are always restrictions. There's never enough space with London sites to do what you should do or want to do.'

Architect Jake Edgley spent six months looking for a site to build a house, partly as a way of launching his own practice. He was on the verge of giving up when he managed to find a site in Islington tucked away behind rows of houses and shops that was being sold off by a larger developer who didn't want the land. As with many of these lost urban spaces, the site was occupied by former workshops that were no longer in use or suited to such a residential area. The derelict workshops were set within a landlocked courtyard, surrounded by other houses and buildings, and accessible only via a slim alleyway that was not big enough for diggers or lorries to pass down.

'It was a leap of faith,' says Edgley. 'Luckily I didn't really know what I was getting into otherwise I might not have done it at all. The reality is that if the sites weren't difficult then somebody would have built something on them already. But being hidden away also makes them great and very private when you do get to build on them. Also, I was given quite a lot of freedom in the design itself by the planners because no one can see these houses.'

Edgley designed two enticing and matching new homes within the courtyard, which is surrounded by brick walls four metres high. Each house was created around its own private internal courtyard, with floor to ceiling glazing to the interiors to maximize light, complemented by rooflights elsewhere in the two storey buildings. But for Edgley, one of the greatest challenges was dealing with the concerns of neighbours and managing twelve different party wall agreements.

'It might be easy for me to say as an architect, but building the house itself is actually the easy bit and finding somewhere to put it is the challenge. These kind of sites do need a lot of personal attention and a very diplomatic way of working. Party wall agreements are not necessarily an issue and most of the neighbours were great. But these projects do rely on reaching amicable agreements with your neighbours. There were one or two tussles along the way and times when it was looking touch and go.'

Eventually Edgely completed the two houses, with plenty of light bounced around the two bedroom buildings by light surfaces and white painted walls, while the exteriors to the courtyard are clad is sweet chestnut for a more organic texture. Edgley sold one of the houses and made just enough on the sale to keep the other – 'The Secret House' – as a home for himself, his wife Katherine Armfelt, a film producer, and their young daughter Sadie. Now, as his family grows, he is already keeping his eyes open for another site.

'If I could find one I would snap it up,' says Edgley. 'I have many clients who would like to build a house and often ask where they can find these kind of sites. If you want to build in London, then these kind of site are the reality, with all the restrictions that come with them. There are some around but it's not easy to find someone who wants to sell and you can't just see them from the street, of course. You won't just walk past one day and see a for sale sign.'

Architect Gunnar Orefelt has been fortunate enough to find backland sites to create his own home twice over, first in Notting Hill and now in Kensal Rise, where he has created a stunning five bedroomed house, with adjoining studio, on the site of a former light industrial unit that used to make shower enclosures. Orefelt bought the site, tucked away behind rows of Victorian houses in this residential area, along with a friend, for whom he designed a separate house right alongside his own. Here, the plot is enclosed by the rear walls of neighbouring houses but large enough to create a garden, while private enough to allow sheets of glazing at the front of the house, as well as a large roof terrace.

'These types of site are ideal if you want to start building from scratch,' says Orefelt. 'We just came across this site by chance and the whole development was very opportunistic. The challenge was really to make light penetrate as far as possible into what is a very deep house.'

Luke Tozer faced rather different challenges when designing an award winning family home for himself, his wife Charlotte and their two children in Notting Hill. Here Tozer came across another unusual site for a home: a tiny scrap of infill land just eight feet wide sandwiched between two large Georgian houses to either side, but which opened out towards the rear. An existing ramshackle home was replaced by a highly imaginative eco house, with the slimmest of facades to the street, but which expands by degrees as the three storey building reaches back to a courtyard, where retractable glass walls allow free flow between exterior and interior.

'Perhaps only an architect would have been crazy enough to buy this site and building the house certainly involved some sleepless nights and early mornings,' says Tozer. 'Developers were put off by the constraints and we thought long and hard about it.'

Tozer threaded a philosophy of sustainability throughout the house, including elements such as a ground source heat pump to provide underfloor heating, as well as rainwater harvesting tanks buried under the courtyard. But much of the inventiveness lies in the plan of the house itself.

'I love how light and airy the house is and how little space is wasted for circulation,' says Charotte Tozer, who works in the City. 'It's very compact and easy to use. It's also very well suited to two small children who have the run of the ground floor during the day while all the built in storage allows toys and stuff to be easily tidied away.'

These hidden homes, then, rise well above the many constraints and conditions which come as standard within these gold dust plots of stray land. For some, they now represent one of the best hopes of building an original home at the heart of the city. And without a visible façade or a strong context from neighbouring buildings, these hideaway houses can offer a greater deal of freedom through design than you might first expect.

'It's not impossible to build but it's not often that a site will present itself,' says Fretton. 'When you are buying a site like this it is usually self evident what kind of a house will come out of it. With a constrained backland site an inward looking quality is inevitable. But it is intriguing to work within the depths of a site like this.'
