Seems like an obvious piece of advice, but a professionally drawn plan will go a long way to ensuring you get the absolute best result possible from your project from quoting to completion.
A landscaping plan will allow the trades to accurately quote on the job ensuring there are no hidden costs to budgeted.
If your landscape contractor is not able to provide you with this service, there are a number of landscape architecture and landscape design firms that can complete this loop. Just as engaging with an architect when building a house is important, the same goes for large scale landscaping. Some of the larger Landscaping companies offer an all inclusive service of design and construction, but may also be able to de-couple the process and allow you to utilise their design arm.
If your design is just a square block of pavers with some garden beds, a professionally drawn sketch like that offered in our On-site Landscaping Consultancy might suffice. But to really get the most out of your yard and to translate great ideas into reality, speak to a professional designer.
