Hornsey's medieval tower, Highpoint, Highgate School and the old Ally Pally station all open free next month. Which need booking, and which you can walk into.

The oldest building in Hornsey opens its crypt and its bell ringing chamber on Saturday 12 September, and you do not need a ticket. We counted 26 buildings and tours within reach of Crouch End in this year’s Open House Festival programme, across Hornsey, Muswell Hill, Highgate, Harringay and Wood Green. Every one of them is free.

The festival runs from Saturday 12 to Sunday 20 September. It is the 35th edition, run by the architecture charity Open City, and buildings across all 33 London boroughs open their doors so people can go in for nothing.

The catch is that the tours worth planning around are ticketed, and booking opened at midday on 19 August. The drop-in openings need no booking at all. Below is which is which.

The nine days are nothing like evenly loaded. Saturday 19 September has ten of the 26 open or running, and Sunday 20 September has eight. The two opening weekend days have five each. The four weekdays between them have one apiece, except Tuesday 15 September, when nothing local opens at all.

Three of those are worth going out of your way for.

St Mary’s Hornsey is the oldest building in Hornsey and the only part of the old parish church still standing. The Grade II* tower was mostly built in the late middle ages, heightened when the church was rebuilt in 1832 and 1833, and it survived the demolition of the rest of the church in 1927 only because its replacement had no bells worth ringing. The Friends of Hornsey Church Tower run guided tours every half hour on the afternoon of 12 September, up to 20 people at a time, taking in the crypt, the ringing chamber and the roof. Tour tickets are issued on the door on a first come, first served basis. The churchyard tomb and tree trails are self-guided and step free; the tower stair is not, and the programme entry warns its medieval spiral steps are “worn and uneven” with a rope handrail.

CUFOS is the former Alexandra Palace Railway Station at the top of The Avenue, N10, now run by a small volunteer charity. It opens for one afternoon only, on Sunday 20 September.

Wolves Lane Horticultural Centre opens on three separate days, including a Friday, which is more than any other site on this list. It has heritage glasshouses alongside its newer eco buildings.

Book ahead: the tours that need a ticket

These need a free Open House visitor account and a booking. Several are single tours with a fixed start time, so they will go.

Highpoint on North Hill is the one to book first. Berthold Lubetkin and Tecton’s 1935 blocks are Grade I listed, the highest grade there is, and the tours are led by the residents. Open City lists eleven of them across Saturday 19 September, each about an hour, running from 10am to 5.30pm. Eleven tours is more than any other local site is offering, which is a reasonable proxy for how much demand there is.

The Crouch End walking tour is the one that starts closest to home. It sets off from Cafe Merro on Crouch End Hill on Saturday 19 September, and the published route takes in Hornsey College of Art, Church Studios, the Floral Hall, Hornsey Library, a lunch stop at Dunns Bakery, the inside of Hornsey Town Hall, the clock tower, Broadway Parade and the former Hornsey police station on Tottenham Lane. It is 11am to 1.30pm and the lunch is at your own expense.

The one day the buses will be against you

Two of the nine festival days are worth checking your travel for.

Friday 18 September is a bus strike day. Arriva London North drivers are due to walk out from 4am that morning until 4.30am on the Saturday, one of eight remaining dates in a dispute over hot weather working. Wolves Lane Horticultural Centre is the only site on this list open that day, and the only bus Open House lists for it is the W4, which is on TfL’s strike list. Wood Green station and Alexandra Palace station are both walkable alternatives, and Wood Green keeps its non-striking routes.

Saturday 19 September, the festival’s busiest local day, falls outside the strike window: the walkout ends at 4.30am that morning. We have set out all eight remaining strike dates separately.

The other thing to note is that Shepherds Hill N6 is booked for multiway traffic signals from 14 to 18 September for BT duct laying, on the road between Highgate station and Crouch End. Our roadworks and travel page has the rest.

What it means for you

  • Register now if you want a ticketed tour. Bookings opened at midday on 19 August, so the popular ones have had six days’ head start on you. You need a free Open City visitor account before you can book anything.
  • Saturday 19 September is the day to clear. Highpoint, Highgate School, the Crouch End walking tour, Muswell Hill Baptist Church, Jacksons Lane, Cumberland Road Studios, both Ally Pally tours, St Mellitus and 18 Lauradale Road are all open or running that day.
  • Sunday 20 September is the second best. The Old Schoolhouse on Tottenham Lane, the old Alexandra Palace station, 1 Halliwick Road, Lauderdale House’s family craft session, Jacksons Lane, Wolves Lane, Cumberland Road Studios and St Mellitus.
  • If you only do one thing and you cannot book, go to St Mary’s Hornsey on Saturday 12 September. Tower tours every half hour, no advance ticket, and the churchyard trails are step free.
  • Check the listing before you travel. Times and access notes are published on each building’s page and can change; the ones above were taken from Open City’s programme on 25 August.

More things to do locally, all year round, are on our things to do in Crouch End page, which includes the Parkland Walk that the Monday 14 September workshop uses.
