We make renovations easy
We handle every aspect of your renovation, from initial planning to final construction. With design, engineering reports, and compliance covered, you won’t have to worry about a thing. We keep you informed at every stage to ensure a seamless, stress-free experience.
Renovation Planning
We design a conservatory that suits your home and lifestyle, whether classic or modern. After finalising the design, we provide a detailed plan and quote. Once approved, we handle property information retrieval and have our draftsmen prepare plans for council consent.
Engineer Reports & Council Consents
To meet post-earthquake council requirements, all consented conservatories in Christchurch need a soil test. We handle this process and submit the results for approval. Standard consents take 4–6 weeks, and we provide regular updates.
Construction & Completion
Once approved, we assign a builder and confirm your start date. Most conservatories are completed within three weeks, and we keep you updated throughout the process. After completion, the council conducts a final inspection, and our team ensures you’re satisfied with the work.
