ᐅ Cold Winter Garden Construction – Wood or Tiles?

Hello,

attached is a photo of our current construction phase. We have installed a glass roof on the house for a future cold conservatory. Also, a side panel has already been added on the left side to the L-shaped blocks.

The right (front post) has a DN50 rainwater drain at the lower end, which currently ends just above the gravel surface. The gravel layer is about 2m (6.5 feet) thick.

The house is a prefabricated home from the brand Schwörerhaus.

We plan to later install glass sliding elements on the front and right side to complete the cold conservatory. The builder of the roof told me that a foundation is needed for these sliding elements (30cm (12 inches) deep, 20cm (8 inches) wide).

The terrace is meant to be 2m (6.5 feet) larger on each side than the conservatory, and I frankly don’t know what would be more sensible or practical to use—composite wood decking (WPC)/wooden planks or paving slabs.

With decking, I need as much free air circulation as possible to keep it dry. However, in my opinion, this also leads to rather quick cooling in autumn and spring. Or can a wooden terrace be made airtight enough for outdoor use? A stone terrace would have corresponding advantages. What is the forum’s opinion on this? Should the slope start under the glass roof in this case or only at the edge outside the shaded area?

How would you handle drainage at the corner post? The builder suggested simply creating a soakaway pit with gravel there and letting the water flow directly beside the post.

What is your opinion on the foundation for the glass sliding elements? If it is to be 20cm (8 inches) wide, then I will always have a 20cm (8 inches) wide concrete wall visible on my terrace. How have you covered or cladded this?

Great! Thank you very much, I really like it! Where did you get the aluminum material from?

We spoke last week with a company specializing in patio roofs and conservatories. Strip foundations are apparently essential because the sliding tracks need to be mounted on them.

In their showroom, they also had an example with a wood/WPC (wood-plastic composite) terrace. Only the guide rails embedded flush in the wood were visible. I need to look up Sonne-Rundum. Their website has several example pictures showing how the guide rails are installed.

We also considered a cold conservatory with fully open sliding elements, but then our newly paved terrace would have to be taken up and redone since it has a slope. The sliding rails require a perfectly level terrace surface.

It now looks like we will settle on a standard aluminum/glass patio roof, combined with under-roof and vertical blinds. However, the quoted price from that dealer was shocking: A 6m x 3m (20ft x 10ft) patio roof with two under-roof blinds and three vertical blinds (1 on the west side, 3m (10ft) wide, and 2 on the south side, 6m (20ft) wide) is supposed to cost nearly €35,000. For me, that is completely disproportionate—even if it’s branded products. The fully enclosed version would cost twice as much! That would be a quarter of the cost of our entire house...

My cold winter garden, including installation, cost less than 40% of the stated amount. Without awnings. Measuring 4 x 5 meters (13 x 16 feet), including glass wedges.

As mentioned, a strip foundation is not necessary; in our case, the guide rail rests on an aluminum beam.

A slight slope is not a problem—we have that as well. The sliding doors don’t move that easily to roll away due to a 2-degree incline. Additionally, the front part of the rail can be slightly raised, which doesn’t really cause any issues. I can gladly take a close-up photo of the detail.

Sounds interesting... However, the awnings are quite expensive. They are from Markilux, and the two under-roof awnings already cost around 6,300€ (about $6,900).
They even want 1,500€ (about $1,640) just for the LED spotlights installed in the rafters! I find that really steep. We will be contacting other companies in the next few days.

Where did you get the canopy from?

Sure, I’ve looked at awnings as well. The entire pergola including the wooden deck floor, rhombus-shaped battens, trellis supports, plants, and lighting will cost me less than a branded roof-mounted awning. That’s why in the conservatory we are sticking with just a sunshade.

Still, 70,000€ (around $74,000) for a cold conservatory is quite a lot. I’ll send you a private message.

The sliding doors aren’t so easy to move that they would roll away because of a 2° slope.

The slope issue would more likely occur if the top were no longer level. However, you can create the slope there as well and slightly recess the track at one end.

Significant engineering costs are included in the price of a branded conservatory.

Yes, please.
