Self Build Homes

Self Building is a method of designing and building your own home, whereby clients are involved in all areas of the project. Self Build homes accounted for over 10,000 new build properties in 2014 – making it one of the largest methods of construction in the UK.

Self Building gives the client more involvement in the design of their home. From day one the client will usually find the building plot, assist in the design process, and even select individual contractors. Some Self Builders will also assist during construction – providing labour and project management.

Over the last few years ACA has refined its service, and we now provide a dedicated service which guides clients through the complete process – from start to finish. We are experienced in working with most councils in Scotland, England and Wales, and have never had a planning permission refused.

We have an in-house energy assessor who provides accurate guidance on heating and energy bills for the proposed house, even at initial design stage. We can also issue Residential EPC energy certificates and are Approved Certifiers of Design (Scotland).

House Extensions

If undertaking a new Self Build home is not the right option for you, but you still need to freshen up your home or create more space, then extending is a great option. ACA provides a tailored service to clients in Central Scotland on various projects – including sun room extensions, attic conversions, garage conversions and large 2 storey extensions.

Our tailored service provides initial design options in our 3D drawing package, Planning & Building Standards approval, and we can then help clients find a suitable contractor.

Our expert knowledge of the new Permitted Development Planning Guidelines allows us to take you down the easiest route to extending your home.
