华丽的北欧后院

I’m looking for concept and design ideas for my old and tired backyard.
My house is located in the northern suburbs of Copenhagen and was built in 1917. Although there've been internal renovations over the years, from the outside the house maintains its original architectural style.

I’m looking for renovation of my backyard and for concepts and designs aligned to the original architectural style of the house.

Budget: medium and cost effective

Transform the backyard so it feels like a natural extension of the house and outdoor living area(s) towards west. A place people want to spend time during the day and night and particular for leisure and dinners on summer afternoons and evenings. For instance dinners right outside the house and a relaxing section at the short side facing north (north-west).

Challenges:
To have a deck or paved ground level area (on the west side) that integrates well with the backyard and with the existing deck on the southern side of the house. (note this deck is not part of the renovation and will stay as it is)
The key challenge is achieving evening sun with a raised deck where the downside is the shading for the west facing windows in the basement. (like the current deck). Alternatively, have a paved ground level deck which will provide light into the basement windows but where there is limited evening sun due to the ground level. This solution will require stairs from the door to the ground level. I am open to radical ideas and designs.
For instance removing quite some cubic metres of soil on the west side, making a bigger space under a lifted terrace (as now), in a way that allows some light to transfer to the cellar windows aswell. This will make space for garden tools too.
But how to solve the part around the nortern corner of the house, I don´t know. Would have to be some steps down to area under the terrace, then some steps up to the terrace. Or maybe to a mediary level on the grass, where the terrace moves out to, before becoming grasslevel terrace on the nortern part of the backyard. See inspirational pics.

On the north side, in the far corner, there has been a garden house. It has just been removed, but there are still bricks in the ground og this area could for instance be used for outdoor planting, se pics for inspiration.

What I would like in order of priority:
· Deck or paved area that integrates well with architecture style of the house and the garden and with the south facing deck. Deck size will have to accommodate table for 6 people. If a raised deck is the preferred solution, an under-deck area for garden tools would be good. Please note the windows for the basement where, ideally, the design should allow for light.

· Backyard utilizing existing trees with new interesting additions of trees, flower beds and planter boxes for spices for cooking.
· Area for movable fireplace
· Area(s) for food spices in plant boxes
· The existing art feature shall remain
Basically Nordic style
