“I was already dreading arranging curtains. Searching for fabrics, calling ateliers, getting everything custom made… it felt like a hassle. With Alto, it suddenly became simple. I chose what I liked, and the rest was taken care of. Now I have curtains that hang perfectly, exactly at the right height, and bring calm to my whole space. Without a doubt the easiest and most beautiful choice I made.”
“I wanted quality that truly felt right, without having to figure everything out myself. I was unsure at first, so I reached out. I received friendly and personal advice and it immediately felt right. The fabric, the finishing, the way it hangs… everything is perfect down to the details. Very happy with the result.”
Alto curtain: made to feel effortless
A space feels different when everything is right.
When light enters softly.
When fabrics move with the stillness of the day.
At Alto, we create custom made curtains that allow your interior to breathe. Not standard solutions, but perfectly fitting curtains, made to the centimeter.
Finding high-quality curtains, especially extra tall curtains, should be simple. But in reality, it is often the opposite. Specific expertise and knowledge is necessary to find the right fabrics and atelier suited for large sizes. You search for fabrics yourself. You compare endlessly. You contact an atelier. And you hope the final result turns out right. Especially for curtains above 2.80 meters, the right expertise is often missing. The right expertise in the sewing atelier and the right expertise to choose the right fabrics. That can be different.
Alto was founded with one clear mission:
to make high-end custom made curtains simple and accessible, without the hassle. For all sizes.
We bring everything together in one process. From fabric selection to confection and delivery. So all you have to do is choose what you like.
We have researched the fabrics fully. Our fabrics are carefully selected based on:
- Quality
- Suitability for large sizes
- Light filtering properties
- Drape
- Durability
So your curtains are not only beautiful, but made to last for years.
We specialize in extra tall custom curtains. But whether your ceiling height is standard or extra high, we make sure everything falls perfectly.
You choose. We take care of the rest.
From advice and measuring to delivery and installation: everything can be arranged, and everything fits, without you losing time.
A home that feels calmer, softer, more complete
The right curtains do more than finish a room. They change how it feels.
