New build or renovate ?

Dupont

Hi all. So cost wise. Would it be cheaper to build or renovate.
Option 1
Bungalow on a lovely private setting, livable by all means at the minute but I’d like to re model it. The half of the length at the front is set back and roof is supported by columns. Would plan to extend these rooms out to that, strip roof and raise it to a dormer or story and half. Would have no need to finish upstairs rooms at this stage. All insulated slabs,new roof, re plaster outside etc. Power, water and phone already there.

Option 2
Lovely site I’ve my eye on. Planning permission should be ok. New build of a dormer or story and half. Just have a working kitchen, bathroom, bed room and living room for the minute. Simply enough spec and finish and around 1800 sq ft. Needs water, electric and phone

I’m in the trade so would be doing a lot myself. Foundations, all block work, concreting, finish floors, plaster inside and out. Bil is sparky and I’d be chasing walls etc, friend is plumber so is the chippy and I’d be helping these where I can. Time scale there is no real rush.

Depends on the quality of the house you want in the end. Obviously a new build will be more energy efficient, warmer and cheaper to run but more expensive to build than a small scale refurbishment. How old is the bungalow? Things get expensive when you go removing the existing floor and doing major work to the existing building. You don’t know what you’d find and it could swallow money. It all depends on the amount of work you intend to do on the Bungalow. For example on this project I’d imagine it would be cheaper to build a new house. https://passivehouseplus.ie/magazine/upgrade/how-to-rescue-a-1970s-bungalow

Pick the one with the best site, it's the one thing you can't change.

Bungalow would be about 30 years old. Cavity wall construction and in very good order.
