It's no surprise that property prices in Luxembourg are high. If you're lucky enough to be a homeowner, you know that every square metre of your home is precious (very precious!).
So it's important to transform these wasted spaces and make the most of every available surface, especially if you want to resell or let your property (which will increase its value).
Here are a few examples practical tips and ideas for transforming wasted space into functional and pleasant areas.
Find an idea for an extra room
The first step in optimising your wasted space is to determine its potential and decide how it should be used.
Here are some popular ideas for transforming unused square metres:
- Creating a small office area : With the rise of teleworking, having a corner office at home has become essential (and, to put it bluntly, very pleasant!). Even small, wasted spaces can be transformed into functional offices with the right layout and furniture.
- Create a reading, yoga or relaxation cornerA nook, landing or small corridor can be ideal for a reading corner or relaxation area. Adding a few comfortable armchairs, a yoga mat, subdued lighting and some storage units can be enough to create an oasis of calm in your home.
- Creating additional functional spaceDepending on the configuration of your home, you can create an extra WC, a small bathroom, a mini-kitchen or even a guest bedroom from your wasted space. This may require more extensive work, such as installing plumbing or electricity (and will therefore be more expensive than installing an office or reading area). However, installing additional WCs is common practice in Luxembourg.
- Lighting up and brightening up the spaceThe idea is not necessarily to create an extra functional space, but simply to visually open up the space with mirrors, murals, pictures or plants. A fresh coat of paint in light tones and well-chosen decorations can transform a narrow, dark space into a welcoming area.
Lost space: optimisation techniques
To make the most of your wasted space, the area must appear larger and more practical than it really is.
Here are a few tips to help you get there:
- Use smart storage
- The wall-mounted storage units, hanging cupboards and furniture with built-in storage units are your best allies. They keep the space clear while offering plenty of storage capacity.
- For example, floating shelves can free up floor space, while built-in cupboards can make use of nooks and crannies that are often overlooked. The result is more storage and more space.
- Make the most of every available space
- Make the most of your lost space. Corner shelves, folding desks and multi-purpose units can turn even the smallest corners into useful areas.
- For your small bedrooms or reading areas, use a bed with built-in drawers or a sofa with storage space under the seats. It's easy to save space.
- Always adopt a minimalist approach
- Keep only what you need within easy reach and store the rest in designer containers such as baskets or boxes. The fewer objects are visible, the larger and more orderly the space will appear. If you leave the objects visible, the space will look busy, and you'll get the opposite effect of what you're looking for (i.e. to create a useful area while opening up the space).
- Use light colours and furniture with clean lines to accentuate the feeling of space and available volume.
- Don't hesitate to use modular furniture
- You can decide to dedicate a zone to several uses. For example, a corner under an attic can become an office during the day, a reading corner in the evening and a guest room at night.
- Multi-purpose furniture, such as sofa beds and extendable tablesThese can be used to transform a room according to the needs of the day. Another example: if you take a desk that converts into a dining table, you can optimise the use of the same space.
