01 - Why Redgate

Why Redgate

Cost blowouts.

Volume builders win the quote with a low number. Then variations start. Cheap substitutions, hidden contingencies, corners cut on quality. By the time you see the real cost, you're locked in and the build is already compromised.

Open-book pricing.

You see every invoice. Trade selection is a conversation, not a decision made for you. Every change agreed, not announced.

The outcome was nine modern studio apartments, each with their own kitchen and bathroom, all on a small site of less than...

Grant recently designed and handled the construction of a new generation boarding house and a granny flat for us, and his knowledge was useful from the beginning.

06 - FAQ

Questions we hear most often.

How much will my project cost?

Nobody can quote a duplex or commercial build off a website. We start with a free conversation about your budget, your site, and what you want to build. From there, pre-construction prices the project component by component against your actual site, so the number you sign is the number you pay.

How can you help me?

Wherever you are in the process. Bare land and an idea, plans that need costing, a stalled project that needs unsticking. We offer design and pre-construction as services in their own right, before any commitment to build. The earlier you bring us in, the more we can save you. The later, the more we can fix.

Is my project right for Redgate?

Duplexes, townhouses, and small multi-residential. Light commercial and industrial. Consultancy on stuck or over-budget projects. If your project fits, get in touch. If it doesn't, we'll tell you on the first call and point you somewhere useful.

Why do I pay for a quote when other builders quote for free?

A free quote is won by lowballing, then made profitable through variations and substitutions you never see. A real quote takes weeks of site investigation, engineering coordination and trade pricing. We call that pre-construction. We invest in it, you invest in it, and if your budget doesn't stack up we'll tell you before you spend a cent. Pay for the thinking. Or pay for the surprises.

Ready to talk about your project?

Grant comes back within one business day. The first 30 minutes covers your site, your planning context, and whether your project is workable. No sales pitch. If we're not the right fit, we'll say so.
