Proposal

side of Flamsteed House, Fell to Ground level and Grind stumps. Low value trees and low retention category (C1) G1 - {Ilex aquifolium (Holly),Taxus baccata (Yew),Robinia pseudoacacia (Locust Tree),Sambucus nigra (Elder),Ulmus procera (English Elm),Acer pseudoplatanus (Sycamore),Acer platanoides (Norway Maple),Crataegus monogyna (Hawthorn)} *Replacement planting below the west facing courtyard PLANTING PALETTE A selection of medium sized shrubs are proposed to replace the removed fig planting. There mature height will not exceed the balcony level to en- sure the newly created views across the parkland can be maintained over their lifetime. The mix is made up of native species that will sit inconspicu- ously amongst the surrounding parkland planting whilst also contributing to biodiversity. Berries and blossom will provide a food source for wildlife. The shrub layer will be underplanted with native spring bulbs to provide colour and interest in the early months before the shrubs have come into leaf. They will also provide insects with valuable early nectar. Shrubs Rubus ideaus, Wild raspberry Cornus sanguinea, Common dogwood Euonymus europeaus, Spindle tree Lonicera periclymenum, Honeysuckle Viburnum opulus, Guelder rose Ruscus aculieatus Bulbs Galanthus nivalis, snowdrop Hycinthoides non scripta, bluebell Anemone nemerosa, wood anemone Ranunculas fi caria, Lesser celendine Narcissus psuedonarcissus, wild daffodil Data via plota.co.uk

Site constraints 11

Scheduled monument: Greenwich Observatory
Scheduled monument consent is needed for any work to it, separate from planning permission.
Nationally important archaeology protected by the Secretary of State. Work that affects the monument or its setting is rarely permitted.
Historic England ↗
Grade I listed: Royal Observatory Flamsteed House
List entry 1358976 · 0 m away · 5 more listed buildings within 150 m (3 Grade I, 2 Grade II)
Listed building consent is needed for work that affects the special interest of a listed building, inside or out, on top of planning permission. Setting can be a consideration for buildings nearby; there is no fixed radius.
Show the other 5 with distances
Historic England ↗
World heritage site: Maritime Greenwich
Nationally designated heritage. Its significance and setting carry great weight.
Registered parks and gardens, battlefields, world heritage sites and protected wrecks are designated heritage assets: harm needs clear and convincing justification.
Historic England ↗
Blackheath conservation area
Demolition needs planning permission and permitted development is restricted.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
Council document ↗
Archaeological priority area
An assessment or field evaluation may be asked for before ground works.
The council or Historic England considers archaeology likely here. A desk-based assessment, and sometimes trial trenching, can be asked for with the application.
Air quality management area: Greenwich AQMA
The council has declared the area as failing an air quality objective.
Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.
Council record ↗
National infrastructure project 517 m away: Thames Tideway Tunnel
The site is 517 m from the project boundary. Waste water treatment, decided. The project page says whether consent was granted. Also within 2 km: Silvertown Tunnel (decided, 1776 m); London Strategic Heat Main Project (at pre-application, 451 m).
Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.
Planning Inspectorate project page ↗
Habitat network: Wood pasture and parkland
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
Radon affected area, class 2; Public transport access: PTAL 1b (very poor), TfL 2023, for the 100 m square; Priority habitat 15 m away: Deciduous woodland.
Not affected
Outside flood zones 2 and 3 · Not green belt
