You need to start with a list which identifies what you want in a garden. eg seating area, eating area, grass, paving, plants for colour, perfume, ornamentals, veggies, herbs, fruit, pond, tree....
Then identify how much time you are willing or able to spend on building a garden and maintaining a garden and also how much money you have to spend on it now and in the future.
You also need to know what sort of soil you have as this will determine which plants can be expected to thrive and which will struggle - it can be clay, loam, sandy, a mix of these in different parts of the garden. Also is it acid, neutral or alkaline.
Lastly, new build gardens tend to have lots of compacted sub soil and all sorts of rubble and gubbins below the surface. Be prepared to do a lot of digging to improve the soil and remove crud and then working in lots of lovely compost and other organic matter to improve the soil.
Get the initial preparation right and you'll have a lovely garden that will make you happy.
