I am looking for my garden to be designed

Require a design layout for my garden
Include summer house - already in garden - but can be moved
Chicken coup for 5 chickens including run - using small shed (already own)
possibly raised beds - including vegetables and flowers
Layout should incorporate bbq, seating area, lawn, a children's swing, considering sun position
Ideas for pathways, and seating areas
Planting for uk climate
We have some ideas for position of summerhouse and chicken coup which may need incorporating but also open to suggestions
Have already had house extension drawn by an architect for home extension, so could send this for inclusion
