There are several ways homeowners are using optical illusions in the home. Be it through mirrors or color, illusions give the appearance of increased space or unusual depth (perception) inside a room.

Some of the most interesting ways these can be used are explained below:

1. Using mirrors to create the illusion of more space

Mirrors are a fairly inexpensive way to increase light and create the feeling of more space, even in very small rooms.  The way a mirror tricks the eye into believing that a room has more space is due to the increase of reflected light from the mirror around the room.

The use of mirrors in this way has led to walls being covered entirely in mirrors. In smaller rooms, this gives them the effect of being larger.

2. Creating illusions with wall art and canvases

While first supposedly used before the Renaissance era, the illusion of trompe l’oeil art – a French term quite literally meaning “misleading or deceit of the eye.” It is something that is also becoming popular inside homes.

While perhaps not strictly kept to their original form, these are extremely realistic paintings designed to fool the viewer into thinking they are real objects. This type of art is often being added to homes to create a 3D perspective on otherwise 2D walls.

3. Painting a pattern around curves and edges of walls at different depths to create a flat image

This takes precision and time. But it is a highly interesting way to view what looks like a piece of 2D art mysteriously suspended in the air. Painted across multiple surfaces, the pattern otherwise seems like random lines. However, when viewed from a specific angle, the image appears fixed in the air creating a highly unusual and eye-catching effect.

This practice, although new, is becoming increasingly used in modern interior design as an alternative to fixed art on walls.

4. Creating optical illusions with unusual furniture

Some of the most regular objects in the house can become much more interesting if they are replaced with well known optical illusion pieces. For example, a flower pot made out of a Penrose Triangle Sculpture – an object which seemingly defies light.

Another example is a bookcase which is at wrong angles, inspired by the popular optical illusion sculpture Café Wall Illusion.  These items present an interesting view on regular household furniture. It becomes a real talking point for those wishing to create simple but effective visual interest inside the home.

There are several effective methods to add interest and depth inside a room.  Even if it is simply adding mirrors or unusual furniture, tricking the eye into believing that there is something more than it seems.

Many of these ideas could become an increasing trend seen throughout new homes. Especially as space becomes more limited and homeowners look to make their property’s unique.
