After I had finished my Archi Masters I was working for an architecture firm who also did a small amount of work for a volume builder. They were actually a pretty good quality builder and at least got the orientation of their 'pre-designed' plans correct. We had the ability to make minor changes to every job and it pained me to see so many simple to implement passive options not being incorporated. Had most of their clients known that they would be saving MONEY over the longterm by making a few minor changes to suit their site, they all would have done it. The problem is unless someone can sell this idea to them as a financial/lifestyle choice, many just think it is about saving the world. It is a no-brainer if you have in interest in it, but for those who don't know, there is no-one there selling it to them, especially on the lower end of the market.

Bigger doors are perfect as a statement but also to move large furniture in; Pivot doors look fantastic but watch out for kids arms getting caught in the gap; once they start closing hard to stop at the short end!

The plan looks a nightmare - bedrooms facing the street, a tiny internal bathroom with no window to the outside (is that legal?) and a "lounge" that looks like it was meant to be a third bedroom. If the internal walls are stud and don't support the roof you're in with a chance, but I'd say to do a proper job the cheap option is NOT going to work. I'd put two bedrooms where the current family room and lounge are and extend the bathroom into the boot room to give window access, or scrap the current bathroom altogether and use some of the space in what is now the kitchen for a new one. Keeping the WC separate is a good move. If you make the street side the social side of the house you can open it right out and create a big front porch that's a social spill-over from the kitchen/dining area, creating indoor-outdoor flow. Planting (two or three shade trees and some stands of tall perennials rather than a "green fence" hedge) keeps your front garden private yet inviting and stops your front porch becoming a stage set for the street. Good luck! I think you'll turn this very ordinary house into a much nicer place to live!

Both. Depending on the look you’re after. For me, it always the lighter.
