The garden survey is just an accurate plan of the garden, like an architect's drawing of a house. So the patio, hedges, walls, level changes, borders, steps and perimeter fencing etc all drawn out to scale, plus locations of large trees and spread of their canopies.
It will allow me to plot the new structure - I want to widen the south and east facing borders, and create west and north facing ones. Then I shall put in paths between the borders and the lawn, so I no longer have the annoyance of plants flopping over onto the grass - they will be able to flow over path instead and not get in the way of mowing. It will also provide a means of getting around the garden without crossing lawn - essential for winter access to the compost heap etc.
Then, I'm considering bisecting the main lawn with another path, covered with a pergola. This would make the part in front of the house symmetrical and reflect the dimensions of the house. It would also create a triangular bit 'chopped' off by the pergola path, which would contain the north facing border (including new magnolia tree) and something yet to be decided. Possibly new location for the trampoline and a better sand pit.
Next phase will be to rebuild the steps that go down through the Leylandii arch into the middle garden. At present this garden is just rectangular lawn surrounded by high Leylandii hedges, with my gunnera and a few old perennials in one corner where the pond used to be. I intend to leave this garden as it is for the foreseeable; it could function as a football pitch/tennis court/run around space for the kids to keep them away from my borders up by the house. One day, maybe I'll turn it into a little 'homage' to Great Dixter's tropical garden and fill it with big leaved craziness. Or a natural swimming pond! Sigh.
The bottom garden will be the functional bit. I already have my lovely new compost bays in there; I need to remove the former chicken run (would love chickens but dh has vetoed) and move the raspberry canes up into the walled garden. Why they were planted underneath the copper beech remains a mystery. The old greenhouse base needs removing, then that area can be a nursery bed < laughs at self for thinking I may one day have the time and the need for a nursery bed>.
LOTS TO DO.
First stage to get it all down on the plan. Then get quotes for the path, steps and pergola building. Then have dh laugh hysterically and point out the leaky roof, rotten window frames and holey pointing. Etc.
Hmm sorry that was a bit of thinking aloud that got carried away there.
