Possible value uplift

A range built from published 2026 Dutch market rates. It is not a quote. Your building decides the real number: its structure, its foundations, its services and what the municipality permits. Finding that out is the first thing we do, and the cheapest part of the job.

Get this checked on your property
What a building of this age tends to bring with it
Asbestos survey needed

The ban only arrived in 1994, so a survey comes first on anything notifiable. About €350–700.

Worth checking the foundations

Timber piles were still going in early in this period, especially in the west of the country.

Empty cavity walls

Cavity insulation did not become standard until the mid seventies, so a full label step is sitting there.

Situations

Does any of this sound like you?

If one of them is yours, we can tell you what it costs and how long it takes before you commit to anything.

“I found a place, but I don't know what it will cost to fix.”

It has been listed a while and the asking price works. What you cannot tell is whether the work behind it is forty thousand or a hundred and forty, whether the layout you want is allowed, and what turns up once a floor comes open.

We survey and cost it before you bid, so you know what you are buying.

“My tenant is leaving. Do I re-let, upgrade, or sell?”

Three options, three very different numbers. The energy label affects both the rent you are legally allowed to charge and the price the property fetches, and the right answer is rarely the obvious one.

We model all three, then deliver whichever you choose.

“The label is dragging the property down.”

A poor label means higher bills, a lower valuation and a rent ceiling set by a points count. After 2030 the worst labels may not be let at all. The measures are known; the order, the cost and the grants are not.

We plan the route to a better label and manage the work.

“We need more space but we can't move.”

Nothing suitable to buy, and moving costs a fortune anyway. So it becomes an extension, a loft conversion, or a serious rethink of the space you already have. It needs a design, a permit and someone to run it.

We take it from idea to permit to finished.

“This house is worth more as two.”

Splitting a property means municipal consent, a notarial deed, sound separation between units, separate services and a build that satisfies all of it. Most of the difficulty sits on paper, not on site.

We run the consent process and the works together.

“I have three quotes and I don't trust any of them.”

The prices are thousands apart, none of them covers quite the same scope, and the cheapest is cheap for a reason you cannot see. The money you spend later is hiding in the exclusions.

We compare them properly and tell you what is missing.

We are not builders. We are the person who makes builders deliver.

The only side we are on is yours.

What we do

How a project runs

  1. Work out what is true

    We survey the building properly: structure, foundations, services, damp, and whatever the previous owner painted over. Then we test what the rules allow against what you want.

  2. Get it designed and priced

    An architect if the job needs one, a specification if it does not, then permit applications and grant applications handled with the municipality directly.

  3. Run the site

    Every trade is directed from one point. We inspect against the contract, chase the sequence so nobody is waiting on anybody, and keep a live budget you can look at any time.

  4. Hand it over properly

    A formal inspection against the contract, a snag list, and money held back until the list reaches zero.

Why NNMC

Renovations rarely go wrong because of bad bricklaying.

They go wrong earlier. Nobody wrote down what was agreed, a decision sat for three weeks, two trades each thought the other had it.

We come from where delivery is measured

In enterprise technology a slipped date is a tracked number reported to executives, not a shrug on site. Years running exactly that at a major corporation, accountable end to end for scope, budget, programme and stakeholders. SAFe and SSPO II certified.

A building site is a delivery problem in different clothes

Specialist teams brought in on contract, not on the payroll. Stakeholders who want incompatible things. A fixed budget, a hard date, and one person who answers for the result. That is a product owner's job description. The material changes; the discipline does not.

Requirements are a document, not a conversation

In our world what you asked for is a controlled artefact with acceptance criteria against it. On most building jobs it is a chat on site that two people later remember differently. That single difference is where the majority of variations are born.

The difference

We did not learn this on a building site.

Most people offering construction supervision came up through the trades. That is real knowledge and we rely on it every day, in the contractors we hire. But that is knowledge of how a building goes up, and your project rarely fails there. It fails in the management of it, which is a separate profession with its own methods, and that is the one we trained in.

The result is not that we know more about bricks. It is that your project gets run the way a corporation runs a delivery it cannot afford to lose: a written brief, a controlled scope, a live budget, a fixed reporting rhythm and one person who carries all of it.

Why it matters

Getting this wrong has never been more expensive.

5–12%Lost to rework, error and delayThe industry average share of project value written off, most of it traced back to agreements and changes nobody recorded properly.
€650 / m²The gap between a good label and a bad oneRoughly 17% between a label A home and the same property at G, and the gap has widened every year since 2021.
~1 mlnHomes at risk of foundation damageAt an average repair cost near €92,000, and not covered by insurance. The cheapest time to find it is before you buy.
