A £1.2M European Union grant has been given for plans at a former school - but it is not enough.
The cash has been matched, but rising costs mean building work looks set to be delayed.
Ambitious plans have been drawn up for the former Christ Church Woodhouse School site in Chestnut Street, Sheepridge.
Housing officials, police and jobs staff will be in the building, which will also house a 32-place nursery and meeting rooms.
Six units are also planned for starter businesses.
Officials have received £1.2m from the EU's Regional Development Fund.
Another £1.3m had already been received.
In a statement a Kirklees Council spokeswoman said: "We were awarded the EU grant of about £1.2m and matched that with other funds, to total £2.5m."
But she added that the council needed to find more money for the scheme.
Tenders for the work were higher than expected because the building industry is buoyant, she said.
The sloping site means the building would be single-storey to one side, rising to two storeys on the other.
The scheme is a joint project between Kirklees, Fresh Horizons - formerly the Deighton-Sheepridge Partnership - and Sure Start, an agency dealing with parents and children.
