Good evening,
We have received an offer from a general contractor and are wondering whether the following additional items are reasonably priced and make sense:
1. Compensation for fittings and sanitary fixtures when purchased by the homeowner (warranty only covers up to the rough installation stage; concealed installations remain our responsibility):
Compensation for ground floor WC: Hand basin including faucet, WC including flush control (flush tank remains our responsibility)
Compensation for attic bathroom: 1 washbasin including faucet, WC including flush control (flush tank remains the responsibility of Bösteinhaus), shower faucet and shower set including rail (connections remain our responsibility)
Compensation: €2,420.00
The sanitary fixtures included would be: Brand Vigour series “Derby” or “Derby Style”, alternatively brand Geberit series “Renova Plan” or brand Villeroy & Boch series “O.Novo”; faucets: brand Vigour series “Derby”, alternatively brand Hansgrohe “Talis S” or brand Hansa series “Hansapinto”
2. Removal of the fixed central mullions on double casement windows, replaced by installation of special flush profiles
Additional cost: 3 windows x €160.00 = €480.00
3. Installation of a secondary entrance door as a wooden door to the utility room, offset against the omitted window, including security fittings and insulation matching the front door, solid door leaf, including locking system matching the front door
Additional cost: €2,020.00
4. Installation of a skylight in the attic hallway, approx. 78 x 118 cm (31 x 46 inches), compliant with the energy saving regulations, brand Velux type GGU MK 06 Thermo (pivot window)
Additional cost: €1,360.00
5. Supply and installation of rough tongue-and-groove boarding, 24 mm (1 inch) thick, made of Nordic spruce or fir, dried, staggered installation with screws onto ceiling joists or collar beams
Additional cost: €1,840.00
6. Concrete staircase, white plastered, with beech steps and risers made of washable white Forex panels, with railing according to building specifications and steel handrail or alternatively masonry railing with internal handrail, with storage room and door under the stairs including light outlet and socket
Additional cost compared to standard staircase: €4,800.00
This “standard” staircase would be: A nicely shaped open staircase with solid wood steps in laminated beech, with continuous railing made of modern round tubing
7. Installation of an additional shower in the guest WC as a flush-floor, tiled design approx. 90 x 150 cm (35 x 59 inches) with installation of one floor drain and required large-area sealing, wall enclosure up to 2.10 m (6 ft 11 in) height according to drawing, shower area tiled to 2.10 m (6 ft 11 in) height; shower faucet and shower set including rail to be provided by homeowner
Note: a shower partition must be installed by the builder on-site
Additional cost: €1,990.00
8. Creation of a tiled niche in the shower in the ground floor WC, approx. 30 x 60 cm (12 x 24 inches)
Additional cost: €340.00
9. Creation of a masonry and tiled shelf behind the washbasin in the ground floor WC, height 1.20 m (4 ft), approx. 0.8 linear meters
Additional cost: €200.00
10. Installation of an additional cold water connection in the ground floor WC next to the toilet (for future installation of a bidet spray by the builder)
Additional cost: €290.00
11. Creation of a tiled shelf next to the bathtub according to drawing, height approx. 50–60 cm (20–24 inches)
Additional cost: €190.00
12. Installation of a laundry chute from the upper bathroom to the utility room (ground floor), 300 mm (12 inches) spiral seam pipe with laundry bag and secured flap for inserting laundry
Additional cost: €1,160.00 (alternative: laundry chute as homeowner’s own work, we provide only ceiling opening 350 x 350 mm (14 x 14 inches), additional cost: €180.00)
13. Installation of all switch boxes in deep form for retrofitting wireless smart home systems by own work
Additional cost: €560.00
14. Installation of AEROPAC SN (Siegenia AUBI) demand-controlled ventilators. Draft-free and whisper-quiet operation, individual air regulation, dust filter function, including core drilling and socket
Additional cost: number of bedrooms 4 x €1,100.00 each = €4,400.00
What do you think?
Are there items that are overpriced?
What would you include and what not? (I know some are very individual. For these, I’m more interested if the additional cost is reasonable.)
Are there individual items I should better leave out initially and commission later with the respective specialist?
We would appreciate any advice.
Best regards

Is €17,300 really cheap for a central ventilation system? It's about a Zehnder system. For me, it seems really expensive for 162m2 (1742 sq ft) of living space without a basement...The extra cost for a Zehnder central ventilation system with heat recovery at our place was €11,400. Our living area is slightly smaller than yours. No basement.

And is this the additional cost compared to window rebate ventilation or compared to a decentralized ventilation system?

But to some extent, we still need to upgrade the electrical work a bit. For example, more power outlets, recessed lights, motion sensor lights on the stair steps, spotlights in the eaves, etc.
However, we wanted to upgrade those directly through the specialized trade, not through the general contractor.Recessed lights in the ceiling? In that case, the appointment with the electrician is actually too late.Similar topics
