We bought a house we could fall in love with, in a market that gave us no choice. A 1980s property with leaks, insulation problems, and a septic tank everyone assumed was broken. It wasn’t.

What followed was 21 months of managing a full internal renovation and a complete extension — foundations to roof level, fit out and finish. Two children lived in the house throughout all of it. Every contractor hired, briefed, paid, and occasionally mediated between when they decided the other trades were the problem.

We ran out of money twice. Took a Credit Union loan to finish the renovation. Switched mortgage providers mid-build and took a top up to complete the extension. Never missed a single contractor payment. Self-managed every trade without a main contractor and saved approximately €43,000 in contractor fees in the process.

I tracked every euro on a spreadsheet I built from scratch, because nothing on the market reflected how a real renovation actually works. Not the aspiration. The reality.

That system — tested across a real project, under real financial pressure — is what you are looking at now. Navigate Your Money Pit exists because I wish it had existed when I needed it.

The house is finished. It is warm and modern and significantly larger than when we bought it. The journey to get there was genuinely difficult, occasionally funny in retrospect, and full of things nobody told us in advance. This guide and the Home Project Control Centre is an attempt to tell you those things now.
