Mid Sussex District Council has given permission to three planning applications.
One application, for a five-bedroom detached house in Courtmead Road, Cuckfield, received 25 letters of objection and an objection from the parish council.
Outline planning permission for this development was already granted.
The council also permitted an application for 13 homes between The Willows and Bennetts Rise, in Southdowns Park, Haywards Heath.
An application for a four-bed house in Hurstwood Lane, Haywards Heath, was also permitted.
