Thanks for sharing, @marymck :+1:

It’s a major redevelopment and will affect the outlook from Sydenham Hill - and also bring 500+ new residents to Sydenham:

As there is no GP surgery in Forest Hill ward this will mean 500-ish extra patients for Wells Park Practice.


Housing is so desperately needed, and the council has quotas of new housing to provide.

Can Sydenham rest assured that one large development of this kind will avoid the housing quota being satisfied by lots of low rise developments?

@marymck makes a good point about the clinic. The pressures on school places will be high too.

I agree that affordable housing is desperately needed. However, the scale of the proposal is enormous. It will be 2 1/2 times the size of Countisbury House (on the corner of Crescent Wood Road).
They are really squeezing the homes in, many local residents had hoped to see something more sympathetic to the surroundings.
Lewisham does not have a great track record on delivering affordable housing quotas in private developments. There is also little joined up planning around transport, NHS etc.
The City of London are planning large housing developments north of the river with no affordable housing included. The issues are complex, however this is a missed opportunity for a special site.


The scale and size of development concern me. Hopefully unfounded and all will be fine but a tad uncertain re. potential overcrowding of already pressed services such as local schools, GP, etc… But then again I guess there is pressure to provide more housing…

The scale and massing is out of proportion with the surrounding area. Tall blocks will stand proud of the tree line.
Residents of 110 new housing units will add pressure to the lack of local infrastructure - schools. Drs surgery, shops - section 106 ( or the newly named NCIL) money will not provide an answer to problems already perceived.


Just a reminder that this Planning Application is still live …

The City of London Corporation (CoL) has submitted a planning application to demolish parts of the Sydenham Hill Estate at the very top of the Sydenham Hill Ridge and build instead high density, urban style blocks of flats that will tower over the tree tops and dominate the skyline.

The Estate is currently made up of three parts: Lammas Green, Otto Close and Mais House.

Lammas Green is a shining example of post-war development at its best. 27 terraced, two storey houses, all with private back gardens and fronting onto a village green of airy beauty. On the uphill side of the green, two low rise blocks of flats were designed to provide a buffer from the roadway.

Otto Close and Mais House were added in the 1970s. Otto Close offers family-sized maisonettes, opening onto a communal garden and adjacent Mais House sheltered housing for 62 elderly residents.

Five years ago the CoL decided to close Mais House and “decant” its residents. Initially CoL said they would refurbish the building and promised residents that they could choose to return. But since then Lewisham Council has claimed there is an over-supply of sheltered housing in our part of the Borough. Now CoL intends to demolish Mais House and build the high density, high rise, general housing development that will see the estate, the Ridge and Sydenham change forever.

No one disputes the need for more housing. But these should be the right developments for the right space. What is proposed is a clear case of over development. Sydenham Society is supporting residents in calling for a co-design approach and for the CoL to work with the community on a design that works for all.

Mais House should enjoy the highest level of protection. It is in a Conservation Area. It is adjacent to Grade II Listed Lammas Green and the locally listed Castlebar care home. Lewisham’s Core Strategy is to protect the wooded skyline of the Ridge.

If tower blocks can be built despite this level of protection, they can be built anywhere – no matter how unsuitable a site.

CoL’s post-war vision in a leaflet given to early residents:

“The lower density was deliberately chosen so as to establish conditions under which a community with its own life and identity might be able to grow and flourish.”

Sydenham Society would like to see that vision suffuse any future plans for the estate.
