To sit and eat outside is one of summer's greatest pleasures. Don't let temperamental climate spoil your plans - come and be inspired by these garden rooms that offer the best of indoors and out, and pick up some tips for building and maintaining them while you're here...

Planning permission:

Slightly different rules apply in different parts of the UK. A general rule of thumb is that you won't need planning permission for an outbuilding with a maximum eaves height of 2.5 metres and a maximum roof height of four metres with a dual pitched roof. Even so, a structure that might not require planning consent in one set of circumstances might need it in another - for example, if your house is listed, you'll need listed-building consent, and similar strictures can apply in a conservation area or an AONB (Area of Natural Beauty). Whatever you are building, it's always worth consulting your local planning officer first. For England, a good place to start is the government's online Planning Portal, which offers quick and easy advice. The rules are broadly similar in the rest of the UK.

Insulation:

It's best to choose a garden room that has insulation in the floor, walls and roof - some of the cheaper log-cabin designs don't have wall insulation. Look for the U-value of the wall build-up, which most insulation suppliers will list on their specification. The lower the figure - measured in W/m2 - the more effective the insulation.

Power:

Garden rooms generally come pre-wired with a good number of sockets and lighting. Many suppliers will also offer the option of exterior lighting, audio-visual cabling and data cables. One grey area is who is responsible for connecting the room to the mains supply. Some suppliers will include this service in the price, while others ask you to organise and pay for it once the building is finished. Prices will vary depending on the distance of the garden room to the mains supply, but you should allow a budget of up to £1,000. All electrical work must comply with current building regulations.

Heating:

Not all suppliers include a heating source in their specification, but however well insulated your building is, it's nice to be able to turn on a heater on colder days. Underfloor heating is a popular option, as are air-conditioning units offering heating in winter and cooling in summer. More basic options include wall-mounted electric convector heaters or portable oil-filled radiators.

Plumbing:

Buyers are increasingly incorporating loos, showers and kitchenettes in their designs. This can be where planning permission gets more involved. Most bespoke designers will be able to offer customers conventional solutions, which tap into the mains sewerage, or off-grid solutions such as composting toilets. As with any electrical work, the plumbing must also comply with current building regulations, whatever the size of the building.

    Located discreetly behind Katharine Pooley's family home in Oxfordshire is a thoroughly stylish shepherd's hut. 'It's a great place to come to for inspiration or to relax,' says the Top 100 designer, who describes her garden room as 'the epitome of elegant camping'.

  • Garden rooms | House & Garden

    This project, designing a shepherd's hut, was not without its challenges. 'The biggest hurdle was the special planning due to the tight dimensions,' says Top 100 designer Katharine Pooley. She decided to take on the task 'with the same approach as any other project' and created a space that would suit playing children and adults seeking a relaxing retreat alike.

    Hand-printed fabric walling and selected antiques add character to the hut, which has a different design scheme to the main house. 'Complete with a sweet kitchen, wood-burning stove, artisan-fitted furniture and a bespoke bed, it has the perfect feeling of cosiness.'

  • Garden rooms | House & Garden

    A muted colour scheme was chosen by Top 100 designer Katharine Pooley for her stylish shepherd's hut due to its limited space. Metallic accents were added with bronze- and copper-toned accessories. 'To finish the look, I used sisal carpet that was seamless and had a country feeling, complementing the choice of fabrics throughout the hut.'

    Designer Sir Paul Smith requested not just a shed from bespoke furniture designer Nathalie de Leval, but 'my Shed', when the two were brought together for the London Design Festival's Wish List exhibition, where emerging designers created something to order by more established design maestros.

    A room that would be perched overlooking an amazing view in the grounds of his house, with glazed Crittal windows, measuring 3 x 3m (the same size as his first shop in Nottingham), where he would have room for a chair and a radio. Inspired by the shed of writer George Bernard Shaw, he requested 'somewhere I can go to really to switch off, somewhere to relax. In today's world where everyone is so busy, I think this is really important and very needed.'

    This shed is just a single room, a 'room of own's own'. Furnished in a restrained but not an austere way, it isn't a monastic cell. Rather, the honey-coloured wood, upholstered and padded seating, the cheeky pop of cheering red and even the slightly kitsch floral oil painting on the wall give the space some real charm and warmth.

    Did we mention this room actually pivots? There's a mechanism that allows it to rotate and follow the sun. The stuff of dreams.

    Richard Parr moved his family from London to this Cotswold farmhouse and developed it into an inspiring setting for his architectural practice. This front porch dining area is the hub of the house in the summer months. The porch was once used, as it is now, as the heart of the building, giving protection to both people and produce; to the right was a cellar, and to the left was room formerly used to make cheese and beer.

    The owners of this Tuscan house decided to make an outdoor sitting area out of a corner of the loggia - an idea that can be applied to any outbuilding in need of a bit of care and attention. Choose pieces made from robust materials like wood and metal, which can tolerate the elements, such as the classic bamboo chairs, wooden table and oak swill-style baskets used here.

    Jane Sacchi recounts the experience of updating a twelfth-century tower in Italy, originally restored by her architect husband Bruno in the Seventies. 'It would have originally been a tower of probably five or six storeys, with a fortified courtyard with battlements and arrow slits. One hundred years later, the property had become a gentleman's residence. One side of the courtyard has an open loggia above, which was originally the banqueting hall.

    In his latter years, Bruno amused himself by decorating the external doors and painting a 'Mondrian' on the loggia wall. This is where I have created the summer sitting room, a corner of shade and the perfect spot to watch the sunset over the distant Tuscan hills.'

    Where do great writers go to dream up their best ideas? The garden of Gipsy House, the home of the late Roald Dahl that provided the inspiration for many of his stories, is permeated with that certain Dahlian magic that is so familiar to anyone who has read his work. Planted by Roald and Wally Saunders - a gentle giant of a builder who provided the original inspiration for the BFG - together they laid the paths, planted the limes, and built this magical birdhouse with window ledges lined with 'dream catchers' (for those not familiar with the BFG, those are, of course, the jars that giants catch dreams in).

    Home to all five Dahl children, his wife Liccy, who still lives at the property, tells how it was the kind of garden where the children would wake to find their names spelled out in weed killer on the lawn to celebrate a birthday.

    Elsewhere in the garden is Dahl's writing hut, which he based on Dylan Thomas's 'word splashed hut' in Laugharne, Wales. Here Roald Dahl would lose himself in his work, writing only in pencil on yellow lined paper - his favourite colour.

    Used as a pre-dinner and drinks area, this amazing terrace by garden designers Dan Pearson and Huw Morgan of Dan Pearson Studio, is paved with local stone that has been colonised with mosses for a softened, natural look. 'The general brief was for a cool, relaxing colour scheme of mainly green and white,' says Dan. 'The Wisteria is grown over a pergola, which is a simple construction. The tubular frame supports a wire grid from which the wisteria branches are suspended with ties. We painted it a dark, matt green so that it is almost invisible between the branches. It is planted solely with Wisteria floribunda 'Alba', which is intensely scented when it flowers.

    The veranda of this holiday home in Cap Ferret was designed by its architect Jonathan Tuckey as the main dining space of the house. 'This was an ideal spot because it leads from the kitchen and has a wonderful view,' he says. Below reclaimed pendant lights from Retrouvius, the 4.3-metre-long table is set before a built-in bench. 'Because the table is so long we wanted to avoid the clutter - both visually and physically - of having 12 chairs, which would have left little space. The owners wanted to make sure they could seat large numbers of people, and a bench allows guests to squash up to add extra places.'

    If you don't want an enclosed garden space, we love the idea of creating an open sitting room, like the owners of this house in France. Comprised of a raised deck area, painted a cheerful duck egg blue, and finished with beautifully carved benches and an almost Gustavian looking table that would be just as at home indoors, the setup has an inviting whimsical feel.

The offset pitch of the roof allowed for a large north-facing skylight; flooding the workspace with natural light.'

    Salvaged from a bramble patch, this Forties British Rail freight carriage has been transformed into a quirky studio by Somerset-based designer-makers Tom Fraser and Lisa Butler, and is one of six available through their company Mungo & Betsy.

    The exterior cladding and joinery is in oak, while the interior is distinctively lined with spalted beech and polished-lime plaster.

    Tom points out, 'With a width of 2.4 metres, length of 5.4 metres and height of 2.2 metres to the apex, it offers more generous space compared to a standard shepherd's hut.' Prices start at £15,000.

    Designed by TDO Architecture for a client in the New Forest, the delightful Forest Pond House is both a space for meditation and a children's den in the woods. Cantilevered over the edge of a pond in a large family garden, this elegant and imaginatively designed outdoor room was shortlisted for a RIBA award and the AJ Small Projects Awards. Made from glass and copper over a timber frame, it cost £7,500 and did not require planning permission.

    This large garden room in south-east London was designed by Charles Barclay and can double up as a guest room. It marks the divide between the main garden and the woodland area to the rear, but the sliding glass doors ensure the full view is not interrupted.
