Tiles There is nothing quite like iridescent tiles for brilliant light bounce-back. Cosmati from Surface Tiles, (top right), mixes materials including stone, mother of pearl and mirror, to really dazzle the eye. From £346.62 a sheet (298mm x 298mm; surfacetiles.com).
(Below right) Fired Earth's new Hexagon Mosaics in white and Moroccan Desert really catch the light and have a beautiful jewel-like surface (£44.99 a sheet or £449.88 a sq m). The firm's Renaissance tiles in gold cost £199.58 a square metre and have a crackle glaze that really catches and reflects the light (firedearth.co.uk).
Hillarys has introduced a customised blind called Torino, made from polyester crepe with a pearlised coating that reflects the sun, not only keeping rooms light and cool in summer, but warm in winter, too.
Torino comes in eight colours, including navy. For even more light, while retaining privacy, choose blinds that pull from the bottom of the window up. From £96, including measuring, making and fitting (hillarys.co.uk).
Paints The Light & Space range of paints from Dulux creates the illusion of more space using something called "LumiTec technology".
The paint contains light-reflective particles to reflect up to twice as much light back into the room as traditional paints, and there are 17 shades of matt emulsion to choose from, including First Frost, pictured below, and Absolute White, pictured above: 2.5l, £25.69 (dulux.co.uk).
Fabrics Danish designer Pernille Holm uses sand (pictured above), or ground-up glass in imaginative ways on fabrics to create light-reflective sheers for Donghia from £260 a metre.
Designer Be Inthavong's silk and leather Heritage Weave fabric collection includes Logo platinum/white (pictured below right) which uses micro-strips of leather, hand-loomed on a silk loom. Find it at Fameed Khalique (020 7490 5524; fameedkhalique.com) at £420 a metre, though you don't need much to make a big impact.
