Thoughts on house types

The overall size of type E is a tiny bit bigger (111.9 sq m as opposed to 111.5 sq m) but type E is longer and narrower than type D. Generally the nearer to square a house is, the more flexible you can be with the use of the interior space, and so the more efficiently you can use it. And so it is here; I haven't measured it, but Type E seems to devote a greater proportion of the interior space to hallway, stairs, landing and correspondingly less to usable rooms. And, again, the rooms themselves tend to be a bit longer and narrower in type E than in type D (with one exception, see below) which means you'll have a bit more more flexibility over the way you use the rooms, arrange the furniture, etc. in type D.

Type E does look as though it might have a larger usable attic space, because of the hipped roof over the front bedrooms. I wouldn't attach much value to that, myself. But it also has the better (larger, squarer) kitchen/dining space. If you see that space as more important than the lounge, that might make you consider type E.

Type D:

It appears that the front windows will be standing out in Type D (by 0.657m) which appears to be wasted space?

I wouldn't think it was wasted space? It could be an ideal space for a desk setup, if anyone was working from home ? Or at Christmas you have a perfect space in your lounge for a christmas tree! l

Utility / Dining room seems better used as well in D.

E's dining room has a more odd shaped space and a smaller utility room.

Doesn't appear to be a bay window, but rather a flat window set in an alcove, so not quite as nice. There are still ways to make some use of that space, though, like a window seat with storage.

If I may add to the advice above about buying opposite a green…

I would advise against buying directly opposite a green. As you'll spend all summer with balls being kicked into your garden (and bounced off you car if you have one).

Green adjacent, would be better! As in end of the terrace, close enough to see kids on the green, but not directly overlooking it. :)

With Type E you can comfortably add an additional two chairs to the kitchen table, good for dinner parties, etc also i think i prefer a larger kitchen, heart of the home, and all that so I would pick E. I have an American fridge freezer that sticks out too much into my kitchen and is one of the reasons i'd like to extend my own.

The smaller box room wouldnt bother me i think people expect these nowadays. I like the idea to add value or at least for that to be possible, so ability to do an attic conversion is a plus for me.

Nope. The stairs needs to be walled in with a fire resistant wall. It is why so few people get proper attic conversions for sale. The legal solution is quite ugly. You also need an alternative exit to the stairs to the attic. You can use a fire ladder for that purpose.

If your conversion:
a) Doesn’t involve raising the roof-line above the existing ridge,
b) Is 50 square metres or less, and
c) Has no more than two habitable rooms,
Then you may use the following fire safety provisions:

1. Enclose the existing stairway with 30 minute fire-resisting walls or partitions
2. Extend fire-resisting enclosure to a final exit (such as the front door)
   OR
   Give access to two escape routes at ground level, separated by fire-resisting construction
