DFG grant extension refusal

Jo324

hello I am looking for some advice or anyone who has been through a similar process. I own my home and live with my son and dog. My mother who is 76 and suffers severe mobility issues with arthritis is now living with me. I am now my mother’s main carer. Her small bedroom is on the first floor alongside our family bathroom. Following an OT assessment 3 years ago it was identified my mum needs assistance and a stairlift, wetroom and wash /dry toilet was recommended. We asked if we could instead have a downstairs extension to enable a small single bed and walk in shower. There are reasons for this. One we do not want to get rid of the only bath we have in the property to replace with a disabled wetroom that isn’t suitable for other members. The bath is used by myself and my son and is very much needed. Secondly we have a dog and use a gate at the bottom of the stairs to enable the dog to not access any part of upstairs. This would have to be removed and we don’t have a solution to this as yet as we cannot allow mum to use the stairlift independently as the dog could impact on safety if no other family members in the house. We feel that the disruption to other family members would be significant and an extension instead would give my mother the privacy needed and enable the rest of the family to not be disrupted. She would then be able to live with us long term and I could continue care. This isn’t a straightforward one fits all case and if the property was solely used by mum we would accept all of the recommendations immediately but it is a family home and unfortunately we have to consider this. We have twice been refused by the home improvements team a ground floor extension although the OT had initially listened to our choice and recommended this. Consideration was given on putting the amount of the adaptions towards the extension but this didn’t not cover even half and we do not have the funds to commit the rest. We feel the only other option is to look at social housing adapted for mum which surely would cost more long term with carers etc needed.
Do we stand any chance of fighting this or should we accept this?
