Building a custom home? Well, that’s exciting!
Right now, probably all you can think of is paint colors and room layouts, right? And once that’s done comes the part that’s even more fun, which is picking out furniture and finishings.
Hopefully, you’re aware of the limits you’ll face later on, because long before you choose the first sofa, the choices you make in the building phase determine what you can and can’t do.
They also decide what will be a piece of cake and what will be a pain.
Forever.
It sounds dramatic, but that’s how it is. The first thing you’re working with is the bones of your house, and if you arrange those bones without thinking about how you’ll really live, you might end up with rooms that are too dark, too awkward, too… Fill in the blank.
In this article, we’ll talk about those early decisions in building that cause you trouble later.


6 Structural Decisions That Box You In
Your home’s frame is something you won’t be able to change later, so make sure you’re working with professionals, such as DG Builders, or any other company that specializes in custom-built homes.
Remember that whatever you choose NOW is permanent.
Here are some mistakes too many people make (and don’t be one of them).
Rooms That Are Sized Too Specifically
You have this idea of the perfect game room, or maybe a huge sofa you want to fit in, so you decide to design the room according to that. And then your kids grow out of games, or you get sick of the sofa.
Then what? If you designed the room to be too narrow or too specific, it will be too hard to arrange things later or to change the room’s purpose.
You want to have rooms that are able to grow and change with you. Otherwise, you’ll be stuck in the same idea forever.
Keeping All Ceilings the Same Height
If you put the same ceiling everywhere, the house will feel a bit flat, even if the ceilings aren’t too low.
In doing this, you’ll miss the chance to make some spaces feel cozy and others grand. Low ceilings can make a room darker and smaller, so unless you want to deal with that for as long as you live in the house, maybe switch things up.
You might think that painting the ceiling a lighter color will help, but it still won’t be a magic wand that will create more space over your head.
Too Many Structural Walls Inside the Home
The actual walls that hold up your house are a big deal, and you need all of them.
The problem is when too many of them are running through the middle of your space because it’s not something you can change your mind about later on.
What happens if, in a few years, you decide to combine the kitchen and dining room?
If you have a load-bearing wall in the way, you’ll need a crazy amount of money for the renovation.
Awkward Hallways and Traffic Flow
You’ll walk your hallways and doorways every day, so if they’re not planned well, it will annoy you to no end.
A hallway that’s too skinny or a door that doesn’t swing the right way will eat into your usable space and make it hard to arrange your furniture the way you want.
Unless you want to bump into things 24/7, pay attention when it comes to designing paths around your home.
Basic Electrical and Lighting Layouts
The standard plan involves having one outlet on each wall and one light in the middle.
And not that that doesn’t work, but even if it feels fine at first, it’s almost certain you’ll want to change this later.
Maybe you’ll want to add light next to your favorite chair to create a reading nook, or you’ll realize that a room is too dark and you’ll want more lights in it.
It’s possible to add this later, but for that to happen, you’ll have to cut into finished walls.
Building Only for What You Need Right Now
It’s tempting to build for how things are right now, but that’s not a good idea. Life changes fast, so always have that ‘what if’ in mind when you’re designing your house.
What if you work from home more? What if your family starts to visit more often? What if you simply want to rearrange everything?
Your home should be able to adapt, not hold you back.


Conclusion
You should be a little bit wiser right now and possibly check your blueprints one more time.
Building a custom home is incredibly exciting, but make sure you’re not obsessing only over the perfect rug or the tiles.
The real magic happens way before that, so don’t forget that you’re not building a house just for today.
This is the first chapter, so give it plenty of room for the plot later on.
