Build a modular home on a site as traditional home is too expensive

Yes you would need to apply for planning permission again as you’re changing the design that was previously approved.

No idea about the price of a well and waste removal.

I have lived in a timber log cabin. No, I dont recommend them. We may not have been totally kosher about it. They are hard to heat in the winter and hot in the summer. you need a dehumidifier running. Can you revisit and block work house again.

I suspect that prices are going to rise with energy cost in the shortly with conflict abroad especially wood.

Did the government not announce recently they are going to make it very easy for everyone to stick a log cabin in their back garden?

Why do people make the assumption that a modular home is a "log cabin".

Log cabins are very unusual in Ireland and simply don't suit the landscape.

Modular homes are simply structures that are mostly pre-made and erected quickly on site and the sooner people realise that these are perfectly liveable structures, many with excellent ber ratings and 40 year guarantees, the better.

In a way they are ideal for one off houses.

A reasonably sized 3 bed modular home will cost about €100k-€120k. - site, base & connection to services incl

Look at framespace , seen a new two story go up in a 2 days seen van parked outside. Very fast roof slates couple days later windows were already in the frames,see different tradesman in while passing it's a lovely looking build, would wonder what the price difference is vs building block. Maybe you could send them your original plans and get them to cost. Then reapply for planning if needed.?
