Pick, together with the Underground board, began working on the extension proposal. Much pressure was also received from a few districts such as Tottenham and Harringay, but it was decided that the optimal route would be the midpoint of the GNR and the Hertford Line. This was backed by the committee, and parliamentary approval for the extension was obtained on 4 June 1930, under the '''''' (20 & 21 Geo. 5. c. lxxxviii). Funding was obtained from legislation under the Development (Loan Guarantees and Grants) Act 1929 (20 & 21 Geo. 5. c. 7) instead of the Trade Facilities Act. The extension would pass through Manor House, Wood Green and Southgate, ending at Enfield West (now Oakwood); based on the absence of property development along the line. In November 1929, the projected terminus was shifted further north to Cockfosters to accommodate a larger depot. It was estimated that ridership on the extension, which would cost £4.4 million, would be 36 million passengers a year. In addition to Enfield West, stations were designated at Southgate, Arnos Grove, Bounds Green, Wood Green, Turnpike Lane, and Manor House. Bounds Green station was almost cancelled in order to improve journey times. A more expensive provision was rejected, which included construction of a third track between Finsbury Park and Wood Green. Furthermore, since journey speed was a primary consideration in decision-making for the extension, the pencilled-in and much lobbied-for additional station near the corner of Green Lanes and St. Ann's Road in Harringay was dropped.
