Extensions and Alterations

Cooper & Withycombe offer a range of services from design of a single beam to create an opening between two rooms to major extensions and alterations of substantial residential dwellings.


We have experience in a wide range residential buildings, including listed buildings,


For larger projects we work alongside the project Architect to design the structure, external surfaces and below ground drainage. 


We also provide contract administration / project management services to obtain competitive tenders, prepare the contract between the client and builder

and undertake contract administration to reduce the cost and time risks to the client during the construction phase.
