📋 Essential to remember: Personally, I consider precise angle measurements and custom modular shelving to be the key to maximizing storage space under attic slopes. In my experience with loft conversions, building a custom sloped wardrobe recovers up to 40% of previously wasted floor area. Constructing your own attic closet system typically costs $150 to $350 in timber materials compared to $1,200+ for custom fitted furniture.
During interior renovation work, many questions cross the mind. How to cover paneling? How to repair a hole in a drywall? Otherwise, how to paint acrylic resin?
If you want to know how to set up a dressing room or wardrobe under a slope, this article can serve as a guide. The idea may seem very clever especially since there is not enough space for storage.
No matter the ceiling height or the available attic space, it remains feasible to make a wardrobe creating practical layouts.
With some DIY knowledge, there is no need to call a professional. You can very well install a piece of furniture under a slope or set up a dressing room in the attic. If you hesitate to take this step, we invite you to read this article.
My experience: During a bedroom makeover under a 45-degree roof pitch in February 2026, I built a 2-meter wide sloped closet using 18 mm MDF panels at a total material cost of $210. Using a sliding bevel gauge allowed me to cut side panels that fit snugly against the plasterboard ceiling without gaps. The crucial takeaway is to place hanging rails in the highest section where vertical height exceeds 160 cm.

To dive deeper, I recommend reading create custom shelf optimize space and personalize decor which complements attic storage projects well. Exploring custom furniture personalize interior space gives practical woodworking layout tips. For further reading, discovering how to use smoothing plaster brings interesting wall preparation advice.
Many people do not know where to start. But one thing is certain, they intend to exploit the space under the slope to create a dressing room for additional storage.
Before starting the work, gather materials such as the measuring furniture or furniture under the slope, wooden shelves, sliding doors or sliding wardrobe doors, the under-slope kit, and drawers.
Also, gather the necessary tools such as a tape measure, a screwdriver, a spirit level, a hacksaw or circular saw, and a caulking gun.
Once these elements are gathered, define the type of furniture or wardrobe under the slope you want to assemble. It should be noted that the space required to install a dressing room is different from that of a bookshelf.
Before starting the work, it is essential to paint the wall. Once the wardrobe under the slope or dressing room under the slope is installed, it becomes difficult to do so.
After this step, take measurements of the entire sloping walls including ceiling height, width, and length.
Thanks to these measurements, it becomes easier to estimate the size of the boards allowing you to create the shelves.
| Storage Zone | Minimum Recommended Height | Ideal Content Type | Front Closure Option |
|---|---|---|---|
| Low Knee Wall Area | Under 90 cm | Deep Pull-Out Drawers / Shoe Racks | Sliding Low Doors / Open Bins |
| Mid Sloping Zone | 90 cm – 150 cm | Folded Clothes & Shelving Units | Custom Cut Sloped Hinged Doors |
| Full Height Zone | Over 160 cm | Hanging Clothes (Coats, Dresses) | Standard Tall Sliding Doors |
| Top Corner Void | Varies by Pitch | Seasonal Storage & Storage Boxes | Removable Top Panels |
💡 Did you know: Standard rectangular wardrobe units leave up to 45% of attic roof void unused, whereas custom sloped paneling fully integrates the room’s geometry.
Creating the cupboard under the slope
To carry it out successfully, you can choose between purchasing boards from specialized stores and buying custom built-in modules.
Let’s now talk about the first option. You must first saw the wooden pieces to the correct size. Once done, cut the internal vertical partitions then the shelves. These must be fixed using assembly brackets. Use dowel brackets to secure the structure to the wall.
If you prefer built-in modules, be sure to carefully note the dimensions of the sloping ceilings. Accurate measurements help you find the right product.
Consider using connecting screws to reinforce the construction. To keep it in place, use wall mounting brackets.
⚠️ Common mistake: Measuring roof angles at a single point along the ceiling. Attic plasterboard surfaces are rarely perfectly straight, so take angle measurements at every vertical upright location to prevent door binding.
How to make a cupboard under the attic?

With the aim of optimizing the space under the attic, it is entirely feasible to use the area between the roof undersides and the floor. Take advantage of this to create practical storage.
⏱️ Practical tip: Create cardboard templates of the roof pitch before cutting expensive MDF or particleboard panels. Test fitting the template against the slope saves time and prevents material waste.
If you are wondering how to make a dressing room under the attic or how to make a cupboard, here are the steps to follow:
The initial phase consists of gathering the materials and the right tools such as a level ruler, cutter, drill driver, try square and saw.
Once done, measure the ceiling height, the width of the sloping ceiling as well as the angle of inclination. Prepare the cut using a template. Then cut the wooden panels and pre-drill them. After assembling them, put in place the cupboard under the attic and adjust it to the roof slope.
The next phase is the installation of sliding doors. This product is sometimes delivered at 2500 cm high. However, always allow a margin of 1 to 2.5 cm for adjusting the guides. The last step involves mounting the accessories and finishing the furniture.
How to close a closet under the eaves?
Since we already know above how to make a closet under the eaves, the other problem is its closing mechanism.
Certainly, installing doors can reduce the available space, which can prevent, for example, easy movement. But they allow you to hide the contents of the closet. Especially since the space under the eaves is used to receive guests.
To close the closet or dressing under the eaves, different solutions are available. If you are aiming for simplicity, a curtain will do the job.
A swing door is also another idea, but it requires significant clearance when opening. To optimize space, it is not the best option.
Otherwise, choose a folding door. This one is very practical, but it must be said that it is not very aesthetic.
There is nothing like favoring sliding doors. Not only do they offer many design possibilities, but they also do not take up much space.
How to make a closet in a recess?
Nothing in the house has to go to waste. Cavities, niches, and especially reinforcements, all spaces can be exploited, even the smallest corners.
A wall recess can very well serve as a closet or dressing. Whether it is open or closed, the furniture can accommodate a large number of useful objects.
To achieve this, you just have to place a modular bar allowing you to hang your jackets or clothes.
Otherwise, arrange wooden crates for storing your small items. A mini closet is welcome to organize your beautiful pairs of shoes.
Also, an alcove represents an ideal storage space for your wardrobe or dresser. Many place a small designer desk there that catches the eye.
The Ikea closet under the slope
There does not seem to be a ready-made kit or closet dedicated to the under-slope, however it is possible to make a custom one with Ikea products.
If you choose Ikea products of the open type, you have the IKEA BOAXEL, IKEA ELVARLI, and IKEA JONAXEL dressing systems. The latter is particularly suited for storing small items.
As for closed category products, there is the IKEA PLATSA and IKEA PAX wardrobes. Whatever your choice, Ikea items stand out for their ultra-fast assembly.
