I wouldn't rush to get rid of the trees - in such an open site they add height, structure and possibly provide some shelter from the wind.
Instead, think about what you want in the garden, e.g., types of shrub, bulb plantings, areas of perennials.
Then try planning it around what is already there - that will show you what might be best moved or altered. Work on paper first, though - much better to have a plan before you start stripping things away and find yourself with nothing more than mud to look at.
