BUILDING SINCE 1962SINCE 1962Your forever home
Treat yourself to designing your own home.

1962. Three generations building in this area.
Fixed price, a completion date with a penalty clause, specifications in writing — before you start deciding anything.
All the upside of doing it your way.
None of the hassle of doing it alone. We coordinate everything. And you don’t pay a developer or an estate agent.
Before you choose a builder
Buy a finished home, or build one to measure?
Both are good ways to get your home. They are not the same.
Buying a finished home
You walk through it before you pay, and you move in sooner.
But someone else chose the plot, the orientation, the layout and the finishes, and the price carries the margin of everyone in between.
Building it on your plot
It takes longer, and the licence and the water and electricity connections depend on the town hall and the utility companies, not on us.
But it is the only way for the home to be yours from the very first line: your plot, your light, your rooms. No one else’s margin in between, with a fixed price and a completion date with a penalty clause in the contract.
Three hand over on time. The fourth does not.
One in four builds does not hand over when it said it would
It is measured by a valuation company approved by the Bank of Spain. And when a build runs late, it usually runs a couple of months late: two months paying for where you live and for the house that is not yours yet.
That is why our completion date is signed, with a penalty.
CoHispania, January 2026.
Six months
One is the foundations, which depend on your ground. The other five are your house.
And this goes in the contract, whether we build your house with our system or with yours:
Fixed price
What you will pay, in writing before we start.
Signed completion date
With a penalty if we run late.
Contract on the table
We show it to you at the first meeting, nothing signed.
The licence comes first and depends on the town hall; we will tell you how long it usually takes in your municipality.
Before you sign
We know what is holding you back.
Building your home should excite you, not make you dizzy. Here, one by one, are the real doubts — and what we do about each of them.
How do I find a builder I can trust?
Three generations building in this area since 1962
Can the budget spiral out of control?
Fixed price, in writing, before we start
Do I save by building, or by buying from a developer?
No developer. No estate agent
What happens if something comes up after the build?
A written guarantee in the contract, and the same hands, in the same town
How will I know everything has been done properly?
8 checks, with an independent laboratory where regulations require it
Will the build overrun?
A penalty for every week of delay, with a cap
None of these is down to luck. It is down to what you sign.
Neither a catalogue house nor a build that drags on for years

Catalogue house
Traditional build
Everhome
The precision of the industrialised, the freedom to build what is yours, and no depending on whether a lorry can reach your plot.
This is what the houses we build look like.
With our system, or with yours
An Everhome house
Our wall and six months of work.
Your design, built by us
If you already have the drawings, we look at them. And if they do not fit our system, we build it anyway, with the system the design calls for.
What does not change is how we run the site: a single point of contact, a fixed price, a signed completion date and the checks done before each thing is covered up.
How we build your home
Eight checks
The ones required by regulations are signed off by an independent laboratory; the rest we measure in your house and hand over to you.
We speak your language
Antonio speaks with you in Spanish, with an interpreter if needed. Everything in writing — emails, WhatsApp, quote and contract — and calls through our team, in your language.
We come in before the architect
You do not need a finished technical design to know what your home will cost.
Since 1962
Three generations.
The trade runs in the family: what is Everhome today started building in this area in 1962.
Here.
The company is in Hondón de las Nieves, in the same place where it builds.
The same person who signs.
Whoever deals with you is the one who runs the site.
25 homes like yours
Around 25 detached homes in this area, as well as public works for town halls and provincial councils.
«Construcciones Antonio Serna was my father’s company. We closed it when he retired, in 2021. This is the same thing, under another name.»
We don’t ask you to trust us. We show you the data.
Eight checks before we hand you the keys, with an independent laboratory where regulations require it. Thermal imaging either shows it in the photo or it doesn’t — no number needed. Façade watertightness is measured before you get the keys, not discovered by you in your first winter.
Continuous insulation
«Fixed price» only means something if you know what is inside it
Foundations, structure, utility connections, kitchen and bathrooms, installations — and also what is NOT included, so you don’t come across it later.
The questions people really ask us
What if your building system fails?
Eight checks before we hand you the keys, with an independent laboratory where regulations require it, and three generations building in this area since 1962.
Can I extend the house later?
Yes, if the buildable area of your plot allows it — we check it with you before designing.
Do you build on rural plots without mains services?
Yes — Autonomy Pack: water, energy and fencing.
Tell us about your dream home. Let’s see whether we can help you build it.
We take on only a few projects at a time, on purpose: never more than three or four builds under way. Tell us about your plot and what you have in mind, and within 48 hours at most we will tell you whether we can help, with the same conditions as always: fixed price, completion date with a penalty clause.
