Planning and building regulation drawings in Emerson Park (RM11)
RM11 holds two very different parts of Hornchurch. Off Billet Lane sits the Langtons group of Georgian and civic buildings, and the High Street leads to the historic setting of St Andrew's Church and its churchyard. Nelmes Way and Berther Road are also in the district. To the north-east the character shifts into Emerson Park, where large detached and semi-detached inter-war houses stand on wide avenues with deep gardens. Hazel Rise, Great Gardens Road, Warrington Gardens and Maybrick Road are among its streets.

That split shapes the work. In Emerson Park the plots are large and the frontages generous, so the questions run to substantial two-storey and wrap-around extensions, garages, outbuildings and sometimes a full replacement dwelling, which always needs planning permission. The limits there come from the established building lines, the spacing between houses and the leafy low-density feel that Havering expects new massing to sit within. Mature garden and street trees frequently carry tree preservation orders, which affects siting and foundations before a design is even sketched.
Near the old core the story is heritage. The Langtons and St Andrew's conservation areas control frontages, setting and materials, and the approaches to Emerson Park sit within their context. Havering has no borough-wide Article 4 direction over householder work here. Sources differ on Emerson Park itself: the council's borough record names it among its conservation areas, while the record for the area lists only the two Hornchurch designations, so we confirm the position for each address. Where an application is needed, an over-scaled addition or the loss of front-garden greenery is resisted.
Planning in Emerson Park: what to know before you apply
Havering treats RM11 as two planning pictures. In the Langtons and St Andrew's conservation areas, roof enlargements, side extensions and rear extensions of more than one storey are not permitted development, and officers focus on setting, frontages and materials. In Emerson Park, outside any designation, an extension within the permitted development limits needs no application, while a larger scheme or a replacement house is judged on scale: whether it respects the building line, the spacing and the green character of the avenue. Tree preservation orders can restrict where and how deep work goes. Flats have no householder permitted development rights. A planning application needs the correct ownership certificate or notice. We establish the designations and any protected trees for your address before drawing.
Applications are decided by London Borough of Havering — its planning pages.
