ᐅ Terrace as a conservatory, or better to use standard full glazing?

Hahaha... me again with my unusual questions...

First of all, does anyone know (I couldn't find anything online) whether a terrace has to be within the building boundary, or if it is also allowed to be outside the building boundary?

We have to build right up to the edge of the building boundary because the neighbor is already close to theirs, and since the sun comes from slightly diagonal right/right, they will partially shade us depending on the time of day and season.

Of course, in addition to the main structure, i.e. the house, we want to have a terrace leading out to the garden (lowest floor, sloped lot, exit to garden).

The floor above (ground floor, street level) should also benefit from the nice view, so we want a terrace there as well.

Since the orientation is east/southeast, so not really full south, I thought that a later addition of a glazed sunroom on the terrace might not be financially worthwhile, because it would be unheated, and in winter, since it probably wouldn't get very warm on the east side, we wouldn’t really get any benefit from the (unheated) sunroom, right?

In summer, we would mostly be down in the garden anyway, or if not, we would prefer to sit outside on an unglazed terrace at ground floor level rather than behind glass.

So I was thinking whether it might make more sense to keep the terrace on the ground floor as is, and instead fully glaze the last 2–3 meters of the back side of the house (facing the garden) completely (possibly adding a small 2-meter (6.5 feet) deep balcony in the dining area so that in summer, when we are not in the garden, we could still sit outside on the ground floor).

Sort of like a little aquarium.
That’s where the living and dining areas are, and there’s no view from the left (just meadow, no buildings allowed) or from the front (meadow/valley, also no buildings allowed), so privacy wouldn’t be an issue.

The question is:
Should I make this a heated sunroom, or would a "regular" full glazing be cheaper than a sunroom?

Always keeping in mind that the house should be between passive house and KfW40 standard. That means not only the walls matter, but also the windows, in terms of heat loss.

Maybe a heated sunroom that can be separated from the rest of the house with sliding glass doors? – Okay, not airtight for sure, and definitely not separate from the building envelope.

Greetings and thanks,

Hi Honigkuchen, a conservatory that isn’t heated is not as bad as you might think. You can easily keep all your plants there over the winter. It’s especially ideal for citrus plants.

Hello,

a conservatory can not only allow you to sit "outside" even in winter, but also help to heat the house. The larger the glazed area, the more sunlight and warmth enters.

Hello,

please also keep in mind that you need a plan for a conservatory, which could delay the start of construction. Additionally, a quality conservatory typically starts at around 150,000 euros.

See you, Hopfen

Hello Hopfen, I think there was a misplaced comma—you probably meant 15,000 and not 150,000 Euros, that would be a very exclusive conservatory at that price.

No hard feelings

Hello Hopfen (I also think, like Daniel, that you meant 15 and not 150 thousand), what do you mean by "plan"?

We will be building together with an architect, and they will create the plan/plans—so floor plans and such.

However, from everything I’ve considered, a standard fully glazed extension would definitely be cheaper than a two-story conservatory, so it would make more sense for us to go that route.

The garden is large enough for a tea pavilion at some point. I can use that as an alternative; although it won’t be heated, at least it’s something.

Best regards and thanks
