Building completed

May 1974.


Seddon House is a terrace on the west side of Thomas More Garden and it runs from Lauderdale Tower to Thomas More House. It joins Thomas More House at the lake end and then runs at right angles to it in the direction of the Museum of London. It is a terrace block supported on unusually tall columns.


Seddon House is a north-south (or side-to-side) terrace, which means that Seddon House has a central corridor along each floor. It is parallel with Lambert Jones Mews which it overlooks, and is oriented at right angles with Thomas More House and Defoe House. Flats are on one or other side of it, with all rooms facing either west over Thomas More Garden or east over Aldersgate Street.

Similar blocks

There are 3 similar terrace blocks: Gilbert House, Mountjoy House and Seddon House. They each have penthouse flats at the top, and regular floors of flats below, but no garden flats. They are also all north-south (or side-to-side) terrace buildings.


There are 6 storeys of flats above podium level with penthouse maisonettes above that. Seddon House has 75 flats and maisonettes, ranging from one-room studio flats to five-room penthouse maisonettes. The flats are numbered 101 – 112, 201 – 212, 301 – 312, 401 – 412, 501 – 512, 601 – 612, 701 – 703. Flats are on one or other side of the central corridor, with all rooms facing either west over Thomas More Garden or east over Aldersgate Street.


There are two entrance doors at either end of the building. (See ‘Lifts and staircases’ below), one near Lauderdale Tower and the other near Thomas More House. The main entrance is at podium level on Seddon Highwalk. 01 level in the lifts is Lauderdale Place, or street level. 02 is a car park level, with no relationship to ground or any structures outside the car park. The main car park is at 03 level, which joins the gardens and Lambert Jones Mews.

Lifts and staircases

An access corridor runs through the middle of the block, with lifts and staircases at each end. Unlike some of the buildings, Seddon corridors have decent central lights. Lifts go as far as the sixth floor. You have to take stairs up to the flats on the seventh floor. The lift lobbies and stairs have exposed granite at the north end, but they are painted white at the south end. There is a staircase with a lift at the south end of the terrace numbered 26; and there is another such staircase and lift at the north end near Thomas More House numbered 25.

Car parking

There is no direct access to a car park. The nearby Andrewes and Thomas More Car Parks are large.At 03 level, arches open on to Thomas More Garden at the south end.  Car owners cross a cobbled road in front of the Thomas More garden flats to reach Thomas More House car park, whose entrance is off Aldersgate Street, just under The Museum of London.


I don’t know what the arrangements are for tenants’ stores.
