Why Alcove Windows Need a Different Approach

Alcove windows are common in British homes, from Victorian terraces with deep reveals to cottage dormers and recessed sash windows. Standard curtains and blinds rarely fit because the recess creates awkward angles and limited fixing space. Made-to-measure treatments are usually necessary, but the choice between Roman blinds, café curtains and shutters depends on privacy, light control and the depth of your alcove.

Before comparing options, check how the window sits in the wall. A deep reveal allows an inside-recess mount, while a shallow one may need a face-fix treatment. Know whether you have a sash, casement or tilt-and-turn window, as this affects clearance.

Measuring and Mounting Basics

For an inside-recess blind or shutter, measure the width at the top, middle and bottom, then use the smallest figure. Measure the drop from the top of the recess to the cill or your chosen finish point. For curtains hung outside the recess, measure the full alcove width plus 10–15 cm each side so fabric stacks back without blocking glass.

Fixing points matter in older homes. Uneven plaster may call for a timber batten or header. Ensure enough depth for the blind or shutter to operate without rubbing the reveal or window handles. If depth is tight, choose an outside-mount treatment that covers the whole opening, such as a Roman blind on a face-fix bracket.

Roman Blinds: Neat and Practical

Roman blinds suit alcove windows well. They sit flat inside the recess or against the wall, so they do not eat into the room or block a window seat. Raised, they form tidy folds that add softness. For shallow alcoves, an inside-mounted Roman blind looks crisp and architectural, especially in linen or cotton.

Light control is good but not complete. Choose blackout lining for bedrooms or dim-out for living rooms. A half-raised blind gives privacy below while letting light in above. Consider chain or cord operation; for high windows, a battery or wand system is worth it.

• Best for: shallow recesses, window seats, tailored looks.
• Watch out for: stacking depth. A fully raised blind needs about 15–20 cm above the window.

Café Curtains: Charming and Flexible

Café curtains cover only the lower half of the window, usually on a slim rod or wire tension system inside the recess. They leave the top clear for daylight while shielding you from passers-by. They need very little depth and can be fitted without drilling into the window frame.

Choose lightweight cotton or linen that gathers neatly. For night privacy, add a lining or a simple roller blind behind. Café curtains forgive an out-of-square alcove because the rod adjusts. They are not for full blackout, but for cottage charm they are hard to beat.

• Best for: kitchens, bathrooms, cottage windows, daylight at the top.
• Watch out for: limited blackout. Pair with a blind for complete darkness.

Shutters: Robust and Controllable

Plantation shutters are made-to-measure and mount directly into the recess. Tilt the louvres for soft light, close them for privacy, or open them fully for an unobstructed view. Full-height shutters suit deep alcoves; café-style shutters covering the lower half work well on street-facing windows.

Shutters cost more than blinds or curtains but are durable and easy to clean. They add a solid, architectural feel to period and modern homes. The main consideration is depth: you need enough recess depth for panels to fold back or slide. For shallow alcoves, choose a tracked or solid-panel design with a smaller projection. On sash windows, ensure the frame does not interfere with sash cords.

• Best for: deep recesses, street-facing rooms, precise light control.
• Watch out for: cost and clearance. Measure recess depth carefully.

Final Practical Tips

You can mix treatments. A Roman blind inside the recess plus curtains outside works well in living rooms. In bedrooms, a blackout Roman blind with a sheer café curtain gives flexibility. Order samples and hold them against the window at different times of day. Check cords and chains are safe for children. If your alcove is unusually shaped or walls are crumbly, a professional fitter is a wise investment. With the right treatment, your alcove window becomes a feature, not a problem.
