DTCE are experts in additions and alterations to houses.
We have worked on thousands of Wellington houses helping turn dreams into reality.

We work with some of New Zealand's top architects and designers or directly with clients and builders.
We are able to work with you from the project inception right through to monitoring construction to check the structural requirements are being met.

Whether you are looking at removing some walls, building another storey, basement additions, decks or retaining walls, we provide cost-effective and robust design solutions.
