Yes. But you have to keep in mind what kind of effort that is and accordingly expensive. The 35,000 EUR for the outdoor area are a better down payment to the garden landscaper. 35,000 EUR is a budget for a, admittedly quite lavish, outdoor area mostly done by yourself, where you only call in the excavator for the rough earthworks in the double-digit cubic meter range.
Because honestly... you don’t want to look at 1m L-shaped stones for your whole life, do you? Something nicer has to be made... but it also costs three to five times as much.
