Buy windows or doors without considering energy efficiency

DIY Vaulted Ceilings

“While vaulted ceilings can make a room look bright and open when done properly, they can also lead to temperature and humidity issues, depending on your environment,” advised Dayna Tooman, designer for Studio Z Architecture. . “Most people don’t know that you need enough space in the ceiling for insulation. Skimping on this can lead to a room that’s too cold or too warm and potentially costly humidity issues down the line. Additionally, you should consult an architect or structural engineer before removing any structural members. »

Not planning furniture placement

Furnishing a bedroom can cost you between $3,000 and $10,000, depending on how many pieces you choose.

“It’s hard to tell visually when you’re in the space, but the measurement will save you a headache when the king-size bed won’t fit with two bedside tables,” Tooman said. “You also want to consider the location of any existing windows in the room. If you’re adding windows to your master bedroom to provide more natural light, make sure you’ve planned your furniture placement before you do so.

Wiener added, “One of the most common mistakes people make is not measuring their space before buying furniture. This can lead to all sorts of problems, from having to order new furniture because the old furniture isn’t suitable, to having to completely redo the renovation because it doesn’t look like what you wanted.

Buy cheap and poor quality furniture

“Just because something is affordable doesn’t mean it’s good value,” Wiener said. “Cheap, low-quality furniture is often made from materials that aren’t very durable and won’t last long.

“This can be a costly mistake, as you may need to replace furniture sooner than expected. When it comes to bedroom furniture, it’s important to remember that you get what you pay for, so invest in pieces that will last for years.

You can potentially spend less than $1,000 to furnish your bedroom, but it’s a waste of money if you have to replace your furniture in a few years instead of a decade or more.

Buying expensive furniture on a whim

“Some homeowners are so excited to start buying furniture and decorating their bedroom that they end up buying the first piece they fall in love with,” said Ana R., co-founder and editor of Design Ideas. Guide. “Most people usually start with large pieces like bed frames, dressers, etc. The problem with this approach is that you are now anchored to this style and color. If you find other pieces that complement each other but not this original purchase, they will automatically be excluded from consideration.

“Before making any major investments, you’ll want to consider your favorite interior design styles, start shopping around, and lay out the pieces that catch your eye. By planning your bedroom layout and furniture in advance, you can potentially save yourself thousands of dollars, hours of frustration, and the terrible feeling of buyer’s remorse.

Overspending on accessories

“It can be tempting to buy lots of fancy bedding, pillows and other accessories; but, in most cases, it’s not necessary,” Wiener said. “Focus on the essentials first, then add extras later as needed.”

Luxury bedding sets can cost hundreds of dollars, while high-quality pillows can cost anywhere from $40 to over $300 each. If you buy additional accessories, such as accent pillows or curtains, you can easily spend hundreds more.

Geometric Accent Walls

You can expect to pay between $80 and $200 to paint an accent wall in your bedroom and between $35 and $150 per square foot if you hire someone to paint a mural on a wall in your bedroom.

“People like to add a splash of color or pattern with a geometric accent wall,” Tooman said. “We suggest using removable wallpaper rather than breaking the painter’s tape. When you’re ready to paint over it in the future, it will be difficult to cover the lines you’ve painted and it can get expensive to repair. »

Not getting recommendations for custom millwork designers

The cost of custom millwork is difficult to estimate as it depends on the designer, materials and price.

“Any custom joinery is another component that can get expensive,” said Dylan Murray of Murray Craft Builders. “Getting personal recommendations for designers/workers/contractors is important. Make sure you are involved in the design process and give final approval on shop drawings of what will be built. Once the shop drawings are approved, the millwork goes into production and it’s too late to make changes.

Not seriously considering electrical components

The average cost to install a single electrical outlet is $210, according to HomeAdvisor. Opening the walls and running the wires can cost between $3,500 and $8,000.

“We redid many rooms during the pandemic to add outlets and lighting to make rooms more flexible for offices,” Murray said. “When you’re renovating a bedroom, you have to think seriously about the electrical components. Wires need to be snaked into the walls, so it can be expensive to do this (or redo it) after the walls are closed.

“Do you have enough outlets to charge your phone and plug in your computer? Is the TV in the right place? Is the office area a long-term decision or should it be designed as a flexible space? Mistakes happen when you move too quickly and make decisions without thinking about it. Adding outlets and redoing electrical work can cost thousands of dollars.
