House refurbishment in Muswell HillMuswell Hill N10 · Houses, flats & bathrooms
Edwardian houses, parade flats and the avenues between them in Muswell Hill, N10.
Muswell Hill was built almost in one go, on a hilltop, by a handful of developers, and four Haringey conservation areas meet around it. From our Finchley Road studio we plan each job around the street, the builder who laid it out and the document that now covers it.

Read the case studyConservation areas
Haringey designated the Muswell Hill Conservation Area on 1 March 1974, the same day as the Fortis Green Conservation Area, which has no adopted appraisal of its own.
The Rookfield Conservation Area followed on 26 March 1976, and Alexandra Palace and Park on 22 September 1978; neither has a current adopted appraisal.
Haringey's 2008 appraisal places Fortis Green to the west of the Muswell Hill area, Rookfield to its south east, and Alexandra Palace and Park along part of its south-east edge.
The Muswell Hill boundary itself has grown twice: in 1991 to roads that reinforce its Edwardian core, and in 2008 by five small areas including Midhurst Avenue, Eastwood Road and part of Alexandra Park Road.
We read Haringey's map for the exact address at the first visit, because a few doors along the same road can sit in a different conservation area, or in none.

History
Haringey calls Muswell Hill an essentially Edwardian suburb: most of its buildings and streets went up between 1896 and 1913, which is why so many houses share their details.
It started when the builder James Edmondson bought The Limes and Fortis House in 1896, planning shops and large family houses for people who worked in central London.
His three storey parades of shops with flats over them came first, followed by Prince's Avenue, Queens Avenue and then Hillfield Park.
To the south and east, William Jefferies Collins laid out his own estate around Grand Avenue between 1901 and 1909, and by 1914 the suburb was substantially complete.
The name is older than any of it: the appraisal traces Muswell Hill to a spring near today's Muswell Road and Wellfield Avenue, the 'mossy well'.
The full story, from the farms to the Broadway, is on our Muswell Hill history and architecture page.

Builders
South of Muswell Road, Edmondson built Wellfield Avenue, Elms Avenue and Dukes Avenue; Woodberry Crescent came between 1906 and 1910.
Other names appear further out: Charles Rook built architect-designed houses on Coniston, Curzon and Cecil Roads, and Josiah Brondson developed Muswell Avenue, Donovan Avenue, Methuen Park and Rosebery Road.
Billy Collins, William's son, kept building flats on Fortis Green and Fortis Green Road into the 1920s and 1930s, among them Fortis Court, Woodside and Twyford Court.
Knowing which builder put up a house tells us a good deal about its joinery, its roof and its plan before we have lifted a floorboard, so we note it on the survey.

Your street
North of the shops, the avenues were built speculatively between 1896 and 1910 as broad, often curving streets of two storey semis behind consistent front walls.
Queens Avenue is the widest of them, a through route between Fortis Green and Muswell Hill, lined with Edmondson's attic-storey houses.
Its paired houses mirror each other about the party wall, with gabled projections, timber balconies set back at first floor and central chimneys.
Woodberry Crescent, by contrast, has roughcast upper floors and some half-timbering over red brick, with houses set close to the pavement.
On these streets a repair is judged against the pair and the row, so we draw the neighbouring house as well as the one we are working on.

Your street
Between Colney Hatch Lane and The Avenue the houses are mostly terraces and linked semis, built for London's growing workforce on long plots with narrow fronts.
Dukes Avenue winds down from the town centre to Alexandra Park, its roofs, chimneys and gables prominent from the brows of the hills.
Windermere, Grasmere and Thirlmere Roads are small two storey terraces on wide tree-lined streets, divided at roof level by brick upstands.
Corner houses here generally turn the junction with a circular bay, a turret or a tower.

Mansion blocks
Along Fortis Green and the south side of Fortis Green Road, three and four storey blocks of flats stand back from the road on large plots, in Arts and Crafts and Neo-Georgian dress.
Birchwood Mansions of 1907, listed Grade II, is the best known, its timber casements glazed with leaded and Art Nouveau coloured motifs.
Fortis Court, opposite, is three linked Neo-Georgian blocks with mostly multi-paned sliding sashes.
Work in these blocks runs through the managing agent, with the common parts protected and the lift and stair kept free for the other residents.

Views
The centre and the ridge along Fortis Green stand above 100 metres, and the ground falls away to the north, east and south, most steeply below the Broadway towards St James Lane.
From the north-eastern streets, Alexandra Palace appears again and again, glimpsed down Rosebery Road and seen at length from the west ends of Alexandra Park Road and Muswell Road.
Haringey's schedule of locally significant views includes Twyford Avenue across the Fortismere playing fields, the line of Cranley Gardens, and Alexandra Park Road at Curzon Road looking out to Enfield and the Lea Valley.
On a sloping street the back of a house can be as visible as its front, so roof and rear designs are drawn from the viewpoints that matter as well as from the garden.

Parade flats
Along the Broadway the parades are mostly three storeys, with shops at street level and homes upstairs reached through common doorways set between the shopfronts.
On Fortis Green Road one parade has two floors of flats entered beneath its paired bays, while the buildings opposite rise to three floors of flats with an attic behind stepped gables.
Haringey's Development Management DPD counts Muswell Hill among the borough's historic town centres and asks for historic shopfronts to be kept.
Work to a parade flat is planned around the shop below, the shared stair and the delivery lane behind, with each agreed before the start date.

Rookfield Estate
Haringey made its Rookfield Estate direction in 1978 for the area known locally as the Rookfield Estate.
The direction names Rookfield Avenue, Rookfield Close, The Chine, The Court, Cascade Avenue, Cranmore Way and set stretches of Etheldene Avenue, Muswell Hill, Park Road and St James's Lane.
At those addresses, planning permission is needed for enlargements and alterations to houses, porches, parking hardstandings, front gates and walls, and for painting brick or render.
Haringey considered replacing the direction but chose not to confirm the new one, so the existing direction still applies; it is one of four conservation areas in the borough with Article 4 controls.

Street fronts
Haringey traces much of the area's special interest to the richness and consistency of the house fronts, and to their setting behind small gardens and low walls.
The appraisal names the loss of front walls and planting to car hardstandings as the change that harms frontages most.
It also lists the details most often lost: timber sashes, panelled doors with stained glass, timber porches, chimney pots, ridge tiles, finials and decorative plaster.
Outside an Article 4 area, Haringey says changing windows and doors or painting a house needs no permission as long as materials and appearance stay close to the original.

Roofs
Some houses were built with wide front dormers, as seen on Grand Avenue, but the appraisal finds added front dormers prominent and disruptive where they were never part of the terrace.
Haringey's policy keeps dormers to the rear and subordinate, allowing a front dormer only where it already belongs to the local character.
Because so many Muswell Hill streets slope, roofs are prominent in views along them.
We start any roof scheme with a photograph of the terrace from the pavement, so that the drawing answers the street before it answers the room.

Listed buildings
The 2008 audit records Grade II listings including Birchwood Mansions and its stable block, The Gables, the Baptist Church on Dukes Avenue and the public library, with the Odeon Cinema at Grade II*.
Haringey's local list adds groups such as houses on Queens Avenue, Queens Mansions and houses on Tetherdown.
For any heritage asset, Policy DM9 asks for a statement of its significance and of how the proposal affects it.

Alexandra Palace
Alexandra Palace opened in 1873, burnt down sixteen days later and reopened in 1875, its railway carried across St James's Lane on a seventeen-arch viaduct.
The line closed to passengers in 1954, and Muswell Hill Primary School now stands where the station was.
The palace and its park became a conservation area of their own in 1978.

Haringey guidance
Haringey adopted its Local Plan, with the Development Management DPD, on 24 July 2017.
Its Policy DM9 asks that alterations and extensions in conservation areas complement the host building and do not appear overbearing.
Haringey warns that applications in conservation areas can be refused on conservation grounds alone.
Its planning advice service offers a meeting within 10 working days where one is needed, with written advice within 20 working days after it.

On site
Haringey allows loud building work from 8am to 6pm on weekdays and from 8am to 1pm on Saturdays.
Haringey wants skip licence applications in five working days before the skip arrives; where it will stand in a parking bay, the bay must also be suspended, booked a fortnight or more in advance.
Scaffolding over a public pavement needs a Haringey licence, and trees in a conservation area need six weeks' notice before any work to them.
We draw up a site plan with the neighbours' access, the skip position and the scaffold line before work begins.

Our approach
At the first visit we record the house, the builder who laid out the street and the Haringey document that covers it. The scope that follows separates repairs, alterations and new building, each with the consents it needs.
The team that draws the application also runs the site, so nothing changes hands between the design, the price and the build.

Questions before you begin
It may be Muswell Hill, Fortis Green, Rookfield or Alexandra Palace and Park, or none of them; Haringey's map settles it for each address.
Source: Haringey Council: List of conservation areas in Haringey
Yes. Its Article 4 direction, which Haringey keeps in force, brings porches, front walls, hardstandings, painting and alterations to houses under planning control.

None was recorded in 2008, and Haringey's current list of conservation areas with Article 4 controls is Noel Park, Peabody Cottages, Rookfield Estate and Tower Gardens.

Seldom: Haringey's policy sends dormers to the back unless front ones are already a feature of the street.
Source: Haringey Council: Development Management DPD (Haringey Local Plan, adopted July 2017)
For a house outside an Article 4 area, not if the new ones match the old in material and look; for a flat, yes, because flats have no permitted development rights.
