Large windows in an open-plan living room are one of those features that estate agents love to shout about, and for good reason. They flood a space with natural light, make rooms feel bigger, and connect your interior to the outside world. But when it comes to dressing them, many homeowners find themselves a little stumped.

Too much fabric and the room feels heavy. Too little and the windows look bare and the space loses its warmth. Getting the balance right comes down to choosing the right window treatments for the scale of the space, and fitting them properly.

Start By Thinking About The Window As A Feature

In a large open-plan room, your windows aren’t just a practical necessity. They’re a visual focal point, and your window coverings should work with that rather than against it. The goal is to frame the view, control the light, and add texture and colour, all without overwhelming the space.

For very wide windows or sliding doors, the most common mistake is treating the whole expanse as one unit when it works far better to break it up visually. Multiple made-to-measure Roman blinds set across a wide window bay, for example, look infinitely more intentional than one oversized blind that strains across the full width.

Roman Blinds For A Clean, Structured Look

Roman blinds are one of the most versatile choices for large open-plan windows. They sit flat when lowered, fold up neatly when raised, and never dominate the space in the way that heavy curtains can. In a contemporary open-plan living room, a row of made-to-measure Roman blinds in a linen or woven fabric adds warmth and texture while keeping the overall look unfussy and relaxed.

For a cohesive feel across a wide bay or set of adjoining windows, choose the same fabric throughout and have each blind cut to its individual window width. The result looks tailored, deliberate, and genuinely polished.

Curtains For Drama and Warmth

If your open-plan living room has high ceilings to match those large windows, full-length curtains are worth serious consideration. Hanging made-to-measure curtains from ceiling height downward emphasises the scale of the room in the best possible way and adds a layer of softness that larger spaces often need.

In rooms that catch a lot of direct sunlight, pairing curtains with a thermal or blackout lining helps manage heat and glare without sacrificing style. Eyelet or pencil pleat headings both work beautifully at this scale, giving clean and even folds that hang well across wider windows.

Wooden Blinds For A Natural, Grounded Feel

For open-plan spaces with a more natural or organic aesthetic, wooden blinds bring a warmth and solidity that fabric alone can’t always achieve. Made-to-measure wooden blinds fit precisely within each window recess, giving a clean built-in look that works especially well alongside exposed brick, parquet flooring, or earthy-toned interiors.

They’re also a brilliant option for managing light levels throughout the day, with adjustable slats that give you real flexibility.
