We have a unique consultation service that can help determine what sort of alteration will best suit your home and your budget

We specialise in alterations and additions, but also build new homes and do maintenance and repair work. Our alteration work has ranged from building on a new deck, or knocking out internal walls to alter the flow and size of rooms, or refurbishing an existing bathroom, to doubling the size of an existing house through the addition of an extension or second storey.

Check out our work here. Our key goal in alteration work is to make sure the renovation is in keeping with the style of the house. If we have done our job properly, you shouldn’t be able to tell we have been there – there should be a seamless flow between the alterations and the original building.
