Someone has now come forward and said that I should lay the electrical lines and lines for the future irrigation myself in advance, then he could carry it out. What that costs, we didn’t get that far, as this approach doesn’t get me any further. I would get bogged down with dozens of individual trades and afterwards it would be a huge mess, no one would know where anything is and so on and so forth......
I believe that is exactly the problem with the whole thing. Most garden landscapers can’t handle such a large project on their own. (For that money most would get their shell construction.) Usually it goes like this: Area A, B, C is done by the garden landscaper and E, F is own work. Maybe someone else comes and does G. Coordinated by the client.
In the end, when you go with an all-in-one garden landscaper, you have a general contractor who has to outsource everything he cannot do himself. Why not a landscape architect who designs everything and then coordinates the construction with the individual trades?
When I read electrical lines, it sounds like more. Where should the sub-distribution go? Has a place already been assigned? Who handles the control? The lights and everything else should turn on and off, for example via dimming or timer. How does the water get from the house into the garden?
