You’ve seen the designs…
spoken to a contractor…
and started imagining yourself in the finished house.
Then the thought comes in:
“Maybe I should just take a loan… and do it properly.”
It sounds like a smart move.
But before you commit to that decision, it’s worth stepping back and asking a harder question:
Can you actually afford to finish the house without depending on the loan to carry you through?
Because building with a loan is about committing your future income to a process that can easily become more expensive than expected.
It’s Not Just Design — It’s a Different Project
One of the biggest mistakes people make is thinking the difference between a bungalow and a maisonette is just “size” or “appearance.”
In reality, it’s a completely different level of construction.
A simple 3-bedroom bungalow is more straightforward to design and build.
Everything sits on one level.
Costs are easier to control.
But the moment you decide to “upgrade” to a maisonette, especially using a loan, you’re stepping into a more complex and more expensive project altogether.
Where Costs Start Increasing Early
The cost difference begins long before construction starts.
A maisonette requires more detailed design work.
The architect has to carefully plan vertical spaces like staircases and how rooms align across floors.
The structural engineer now has to design a system that safely carries an entire extra floor, introducing columns, beams, and reinforced slabs.
Even the quantity surveyor has more work to do, measuring and pricing a more complex structure with more components.
So right from the beginning, your project has already moved into a higher cost bracket.
Your Soil Can Change Everything
Another factor many people overlook is the ground they’re building on.
If your land has black cotton soil, for example, you may need to excavate much deeper to reach stable ground.
That means more labour, more excavation, and more materials.
In some cases, you may even need a suspended foundation system, where the structure is supported rather than resting directly on the soil.
This can significantly increase your foundation costs, before you’ve even started building upwards.
Structure Isn’t Where You Cut Costs
Once construction begins, the cost difference becomes even more obvious.
A maisonette requires a structural framework of columns and beams to support the upper floor.
This introduces more steel reinforcement, more concrete, and more skilled labour.
Unlike finishes, these are not areas where you can “adjust” or compromise.
They are essential for safety.
The Hidden Cost of the Upper Floor
Adding a second floor means a suspended slab system, which involves formwork, reinforcement, and concrete.
Then comes floor screed to level the surface, followed by tiling, adhesives, labour, and finishing details like skirting.
Each of these is charged per square metre.
So the moment you add another floor, you’re effectively doubling a large portion of your finishing costs.
Finishes Add Up Faster Than You Think
Finishing is often underestimated because it feels optional or flexible.
But in reality, it’s driven by surface area.
More walls mean more plastering, more skimming, and more paint.
Ceilings also become more expensive.
You may need to plaster the underside of the slab or install gypsum ceilings, sometimes for both floors.
These costs don’t come all at once.
They accumulate quietly as your project grows.
The Reality of the Loan
Here’s where everything becomes personal.
A loan doesn’t adjust when your project becomes more expensive.
It doesn’t slow down when construction delays.
And it doesn’t wait for your house to be completed.
Every month, repayment is expected, whether you’ve finished building or not.
If your budget stretches, you’ll find yourself managing two pressures at the same time:
construction costs and loan repayment.
A Smarter Way to Approach It
If your current budget can comfortably build a complete bungalow, there’s real value in finishing that first.
You move in, stabilise financially, and avoid unnecessary pressure.
If your long-term goal is a maisonette, you can plan for it.
For example, a flat roof bungalow can allow for future expansion when you’re in a stronger financial position.
That way, you’re building in phases; on your terms, not under pressure from a loan.
Final Thought
Taking a loan can help you build faster.
But it also adds weight to every decision you make during the process.
So before you commit, take time to understand the full scope of what you’re building
Not just how it looks, but what it will truly cost to complete.
Because the goal isn’t just to build a house.
It’s to finish it… without regret.
