Floor plan of corner terraced house in planning - suggestions for changes?

We also have a step to our balcony, that is normal because of the extra floor construction that is needed. But I don't find it bad at all. If it were an apartment and I had to go out there every day with a food tray to my only balcony, it might bother me. But as a balcony for now and then? The red dashed line could possibly be a cladding, for example with drywall panels. But that's just an idea, I don't really know.

So, I’ll write something about the sample selection and what it costs, whether we should have it done somewhere else ourselves, what you paid for it... ultimately I found out that certain builders negotiated these prices themselves, so I know if I can demand something price-wise... It would also be nice to see if the offers are complete:

1. We want a washbasin in the utility room in the attic:
The offer for this:
Supply and installation of a laundry sink in the attic utility room including the creation of cold and wastewater connections as well as the necessary fittings. The laundry sink and necessary connections will be surface mounted. For 700 euros

2. We want all the windows in the attic in size 114 by 140 cm
The offer for this:
1 x surcharge for enlarging the roof window in the utility room from 65x118 to 114x140 1 piece 527.00
2 x surcharge for enlarging the roof windows in the bathroom and studio from 94x118 to 114x140 2 pieces 554.00
Total 1081 euros

3. Then we wanted at least in the living room instead of normal roller shutters, blinds so that you can create shade without it getting completely dark... in the construction specification there are normal light gray roller shutters... our window frames will be anthracite, thought it would look nice... but totally expensive,...
The offer for this:
Delivery and installation of electrically operated venetian blinds (anthracite gray RAL7016) instead of the normal roller shutters in the living/dining area 15.9 m² 225.00 3,577.50

4. Sliding door in the bay window or in the living room, depending
The offer for this:
Delivery and installation of a lift-and-slide door, width 2 m. The door has a lift and slide function. The sliding door consists of one fixed and one sliding element. The designation of the fixed and sliding elements is determined during the construction planning. 2,900 euros

But I heard from our neighbor that he paid 3,000 for a large 4 m sliding door, you can negotiate here. One door 2,900 ..... if sNN ONLY IN THE BAY WINDOW we thought

5. I would like to take simple roller shutters but in anthracite, the price only includes light gray standard ones,...

Delivery and installation of colored exterior roller shutters in anthracite gray (RAL7016). It must be ensured that aluminum roller shutter slats need to be fitted on. 36.96 m² 35.00 1,293.60
Delivery and installation of an aluminum roller shutter slat instead of the standard PVC roller shutters. 36.96 m² 65.00 2,402.40

Total price: 3,696 euros

6. Roof window roller shutters cost around 5,000 euros,... oh man,... I don’t believe that!

7. Then the roof overhang is in wood color, we want it white

The offer for this:
Roof overhang painted solid white. WARNING: By applying paint on wood, cracks can occur due to wood creeping and shrinking, which are visually enhanced by the paint. 27.5 linear meters 65.00 1,787.50 Total price EUR 1,787.50
Also find that ridiculous, we will buy a bucket of paint and my husband will do it himself, there will be scaffolding anyway. Won't cost us 100 euros. Unbelievable!

8. We want colored windows in anthracite and anthracite door for 2,800 euros instead of white windows. We have an aluminum door here that we don't want. I don't know if the price of the window colors changes if we only take those, I think anthracite windows still cost 2,800.

9. We have a plastic door, want an aluminum door. We were at the door supplier, he gave us an offer for 2,500 euros for the front door. Is a plastic door that bad?

Looking forward to what you say,.....

I can't say anything about the prices, but for the 2m door I would consider making a lift-and-slide door. You can only open one side, but the opening is not 1m wide, because you also have a frame that you have to subtract. For 2m width I would take a double-leaf door.

I can't say anything about the prices, but for the 2m door I would consider making it a lift-and-slide door. You can only open one side, but the opening is not 1m wide, because you also have a frame that you have to account for. For 2m width I would take a double wing.

I don't understand that,... so normal doors open both sides.... With sliding doors, less opens, right?

What wants to say is that a lift-and-slide door is actually not worth it with only 200 cm width. The opening part is at most half, and it can hardly be slid completely away, but usually some part of it remains in the opened section. If, on the other hand, you have hinged doors, you can open the passage completely and, just as your windows are positioned, the opened wings can also be well tolerated. You just have to pay attention to which wing should reasonably be able to open first at which window position. But you have to consider that with the sliding door as well.

What means is that a lift-and-slide door is actually not worth it with only 200 cm width. The opening part is at most half, and it can hardly be slid completely away; usually, some of it remains in the open section. In contrast, if you have hinged doors, you can open the passage completely, and, given how your windows are positioned, the opened wings are also quite manageable. You just have to pay attention to which wing it makes sense to be able to open first depending on the window position. But you have to consider that with sliding doors as well.

Thanks for the explanation, then I did understand it correctly after all. Exactly, I’ll skip the sliding door,.....Our neighbors took a 4 m door in the living area, visually it looks great, but I’ll also do without that....for cost reasons, I think the door costs 3500...but also because I like it when the wings open and you can go out onto the terrace in two places...

Thanks also for the tip on which wing should open how...the left door opens first on the left, and the right door opens first on the right...we already discussed that here.
