This pub is not only a grade II listed building, it is also on the Campaign for Real Ale’s (CAMRA) Local Inventory as having an interior of local historic interest, and the description is as follows: "Re-built with adjoining block of council flats in 1929-30 as part of the Ossulston Estate to designs of the LCC Architects' Department under G Topham Forrest. A three-storey building of rendered brick and has four operational/blocked doorways indicating a multi-roomed interior originally but It now consists of two bars with the rear bar mainly a function/meeting room.

The front bar seems to have been three rooms as indicated by the three doors on the Phoenix Road side. The small front bar is U shaped with the counter on the left having a sloping front with wood staves but the right hand side (divided by the counter access door) has a flat panelled front. There is a groove in the left hand side of the access door column that may have had a screen/panel attached that lined up with one of the blocked up doors which would indicate a former off-sales here. The large area to the right hand side has an original fireplace and stairs. The walls here are covered with timbers frames painted blood red with white painted wallpaper panels. The ceiling is decorated with oblong sections with moulded cornices again painted blood red.

The large room to the left rear in Chalton Street has a long L shaped bar counter with sloping wooden staves similar to the left hand section of the front bar but painted green. Modern bar back here but look for the leaded stained glass panels above the staff door to the right hand rear which looks to be original. There are two load bearing columns with wood covering here with one by the entrance with a short half height partition to the door. Similar ceiling to the front bar but different colour scheme. Modern wood effect flooring throughout both bars. Notice the heated foot rail that runs across the bottom of all the bar counters. There are a number of cushioned wooden bench seating in both bars that have an inter-war style to them."

The listing description is as follows: "Block of council flats and attached public house forming part of the Ossulston Estate. 1929-30. To designs of the LCC Architects' Department under G Topham Forrest. Load-bearing brickwork rendered with coloured roughcast, ground floor channelled to appear as stone; reinforced concrete balconies. Hipped pantiled roofs with dormers and tall chimney-stacks. EXTERIOR: flats: 5 storeys, attics and basement. Long range of flats with central round-arched entrance with voussoirs and keystone. Slightly recessed sashes with exposed boxing. Parapet. Public house: 3 storey and cellars. 4 windows and 6-window return to Chalton Street. Similar style. Public house frontage of transom and mullion windows with plate glass between pillars; main entrance on chamfered ground floor angle. INTERIORS: not inspected. This complex forms a group with Chamberlain House, Phoenix Road (qv) and Levita House, Ossulston Street including the Somers Town Coffee House (qv). HISTORICAL NOTE: despite policy to house as many Londoners as possible on outlying cottage estates pressure of waiting lists and urgency of slum clearance forced Cecil Levita, Chairman of the LCC Housing Committee to review the situation. The Ossulston Estate is the most important inner-city estate of the inter-war period, representing the most considered attempt by the LCC to inject new thinking into inner-city housing estates. It was influenced in particular by Viennese housing models and was innovative in terms of layout and elevation."
