You can save the money for the architect and use it sensibly for planting. First, if I were you (that's how we did it), I would look for an online garden planner. Recently read from : Gardena Garden Planner. I used the mein-schöner-Garten garden planner. At the same time, invest in a yearly library subscription and borrow all garden books for a month. There you can learn about the different styles. Learn the rest about plants or get ideas via Google. Affordable: at the hardware store, concrete stones (30 x 30 or 50 x 50). You can design paths at intervals with them. Either in gravel or simply with those wood chips (I can't recall the name right now). My opinion: side paths in the garden can also settle; you can lay the stones without a sand bed or let it become a beaten path. Foil should be under the main paths or at the house edge, but the house edge is, in my opinion, a professional matter so that work at the house is done properly. For that, hire a landscape gardener. The honeycomb thing costs too much and only works with fine pebbles. But pebbles get tracked into the house, so skip that. Better to use coarse gravel. What I would have done: the edging of the house, at least the border stones; they must be set in lean concrete or concrete. The terrace also needs a good base, otherwise it will sink. The rest you can do yourself. Either start now, get seedlings for a hedge to root, or later use an affordable online shop. Compare prices at nurseries, hardware stores, or garden centers: there are definitely inexpensive bushes and trees that still make a good impression later, yet these are not rare. Sensitive or rare plants, but also older or bigger ones, are usually very expensive. They also like to give tips on design. Always check Ebay classifieds from March on; there are often people dissolving or changing their garden. For privacy and wind protection, you can use bamboo mats, either let them rust or let plants grow over them. We first sowed lawn everywhere. But once it has grown, it's tedious to dig it up again. But for that, you have the men. We started in March and finished in November. It will continue again in April. And now back to planning: sight lines in the house should always be extended through the windows to a nice view. So imagine and design the window like a picture: either a bench with a tree, or symmetrical, or create depth with different growth heights. Piles of stones are also nice. At flea markets (and again Ebay) or at the hardware store's sale corner, you can still find some bargains: large containers, wrought iron grids, fence parts, wooden chairs... ideas come all by themselves. A formal garden is more difficult. It looks nice too, but do you want to live in such a showcase garden? You can do without a covered terrace (an umbrella will do), fountain (very expensive), pond, and expensive materials. We had our soil enriched with humus. But honestly: in our old townhouse garden with clay soil, everything grew that we simply buried there. Potting soil is expensive! What should also be included: a large bottle of muscle and relaxation bath! Have fun wishes Yvonne
