Summit Construction is a renovation, extension and architectural build firm in Christchurch, with its office on level 1 at 257 Lincoln Road in Addington. The firm calls itself a one-stop shop for renovations, extensions and architectural new builds across Christchurch. It manages each project from architecture, engineering, quantity surveying and geotechnical engineering through to council consents, subcontractors, project management and trusted suppliers. Its process starts with a meeting to understand the client's goals, then a fixed-fee agreement to manage design and planning. The firm offers a free initial meeting and a no-obligation estimate, and a free client portal shows key dates, project stages and a to-do list for the client. In 2024 the firm received the Canterbury Master Builders House of the Year Silver award.
