FAQs
Common questions before you start.
Is going up or out better?
It depends on the block, structure, approvals, budget and lifestyle goals. CSN helps assess the most sensible pathway.
Can an addition improve the whole home?
Yes. The strongest additions usually solve layout, light, thermal comfort and flow - not just floor area.
Do you handle first and second-floor additions?
Yes. The current CSN service offering includes first-floor additions, second-storey additions and extensions.
Client proof
Communication and workmanship matter.
CSN Constructions did an outstanding job for us. Their attention to detail was incredible, the communication throughout the project was clear and consistent, and their knowledge really showed in the quality of the final result. Couldn't be happier with the work - highly recommend!
We had the pleasure of working with CSN Constructions on a passive South Coast build, and I cannot recommend Chris and his team highly enough. From the very beginning, the level of professionalism, communication, and genuine care stood out.
CSN have completed several jobs for us and we have found the team consistently professional, high quality and on time. Christian is clear on timelines and keeps us informed with regular updates.
