The factors that would need to be taken into account when developing a budget include (but are not always restricted to) the following:

• Surveys required (topographical, ecology, archaeology, tree, etc)
• Site constraints
• Is consultation required?
• Planning permission application fee
• Travel costs including site visits required
• Is an LVIA/EIA required?
• Quality of finish (higher quality = higher budget)
• Timescale (quicker response = more expensive)
• Planting species specification (mature trees = more expensive)
• Project management; number of visits required, skill of contractor.
