Tenants and residents with a Tenure Tenancy agreement have significant rights during redevelopment, as outlined by the 1969 and 1996 Rehabilitation Acts. These rights include negotiating discounts on additional square footage, receiving full area without construction costs on original square footage, and securing free or discounted car parking. Builders must also provide suitable temporary housing in the same locality and present a detailed project plan and bank guarantee before commencing any redevelopment.
