Material matters

Bespoke hardwood conservatory, from £40,000, Vale Garden Houses.

The materials most often used for garden rooms are uPVC, metal and timber and each has advantages and drawbacks. The affordable option is uPVC – it’s brilliantly low maintenance but the design options are limited. At the high end of the price range there are aluminium and steel-framed garden rooms. The strength of the metal allows for a slimmer framework and powder-coated finishes give long-term protection against the weather. As a garden room building material, timber has beauty and strength but it must be properly maintained to keep it in good condition.

Floor tiles

Da Vinci flooring in Dune with 3mm design strip and Davyne border, £42.99 per sq m, Karndean Designflooring.

Flooring that’s easy to clean and can stand up to heavy wear is wise in a garden room, which can be a busy through route. Hard materials like stone, ceramic, encaustic and porcelain tiles all meet the criteria and some can be used in and out, so you can extend the flooring onto the terrace. Laminated, vinyl and engineered wood are attractive and sometimes more affordable choices and, like stone and tiles, can be used with underfloor heating.

Garden room furniture

Concrete-topped Hudson table, 150cm diameter, £1,390; Harrington all-weather wicker dining chairs, £265 each; Corinium tall jug, £11, all Neptune.

Base your choice of garden room furniture on how you’ll use the area, as well as how you want it to look. If it’s to be a family room, make sure there’s plenty of seating but choose shapes that won’t crowd the space. Sofas and chairs with legs have a light and airy look and upholstery in pale, neutral colours will be slow to show fading. For a conservatory feel, rattan furniture is a versatile option. Available in classic and mid-century designs, it’s resistant to sunlight and can be used inside and out, though natural rattan – new and antique – must be brought indoors in wet weather.

Choose your windows carefully

Bespoke double-glazed traditional conservatory in Drab colour powder coated aluminium, from £50,000 plus building works, Marston & Langinger.

Glass makes up the largest part of a garden room and developments in technology mean the space can be used all year round. Double glazing and energy-saving low emissivity (Low-E) glass are the minimum requirements to keep the interior cool in summer and prevent excessive heat loss in winter. Using argon gas-filled double-glazed units or triple glazing will increase thermal efficiency further. Tinted or metal-coated solar-control glass will help protect against glare and strong sunlight, while self-cleaning glass makes exterior care easier.

Custom-made roman blinds, from £72.55, English Blinds.

Include house plants

Bespoke timber orangery by David Salisbury. Prices for conservatories and orangeries start from £35,000, excluding building works.

Orangeries were built in Britain in the 17th century so citrus trees could survive in our climate. ‘Citrus trees like very bright conditions, which is why they are good plants for a conservatory,’ says Andrew Kyte of The Chelsea Gardener.

Consider your lighting

Large hexagonal lantern, £35; small hexagonal lantern, £25; Ombre tumbler, £3; Dip Dye runner, £25, all Marks and Spencer.

After dark, conservatories need light to bring them to life. Wall lights will highlight brickwork and other textured surfaces, table lamps create a cosy glow and decorative lanterns and candles on the dinner table add a magical touch.

Think about how you will use the space

Bespoke aluminium and glass lean-to with bi-folding and patio doors. A similar structure by Apropos costs from £32,000.

No longer regarded as a summer room or even one that’s used only on sunny days, conservatories and orangeries are home extensions designed for everyday living. Use yours as a dining area, playroom, study or art studio – there are few limits. Some are so well integrated that, like this glass-roofed side extension on a terraced house, they straddle the line between garden room and glass architecture. Light, bright and now with efficient ventilation and solar control, they make spacious kitchen-dining rooms that are enhanced by folding doors that open out to remove any boundary between inside and out.

Be careful with antiques

An old-fashioned style garden room filled with plants
This powder-coated aluminium conservatory is furnished with rustic and weathered finds. Prices for similar garden rooms by Marston & Langinger start from around £50,000.

Garden rooms lend themselves to vintage style, but do find a shadier spot in your home for antiques such as fine wood furniture and textiles that could be damaged by the sun. Instead, stick to objects made from less vulnerable materials like stone, glass, iron and terracotta.

Fit roof blinds

Grenoble Cream pleated roof blinds, from £53; Sasso Aqua pleated window blinds, from £45 (prices include measuring and fitting), all Hillarys.

When it comes to insulation and solar control, there are conflicting views about the use of tinted glass as it subtly alters the colour of natural light entering from above. An alternative – or additional – solution is to fit roof blinds. These come in a choice of styles including traditional pinoleum, roller, pleated and Duette honeycomb pleated with varying levels of translucency. Some have a reflective coating to enhance solar protection and keep the room cool. All are made to ft the individual panels and can be controlled manually or remotely.
