Granny Flat Site Planning Software

Built for Granny Flat Installers

Confirm Viability Faster.
Approve Granny Flats Right the First Time.

Granny flats are small projects with complex compliance. Setbacks from primary structures, maximum coverage rules, minimum lot size requirements, and council-specific overlays all shape what can be built and where. uDrew surfaces those requirements instantly, so your team can confirm viability, design compliantly, and move customers to approval with confidence.

Three Tools. One Workflow.

Everything Granny Flat Installers Need in One Platform

uDrew gives granny flat installers the ability to assess site feasibility, design compliant layouts, and present verified options to clients, all from one connected platform.

uDrew OnSite

Assess Feasibility in Seconds

Enter the property address and uDrew OnSite immediately checks the planning controls relevant to secondary dwelling construction: lot size thresholds, setbacks, coverage allowances, height limits, overlays, site engineering, and council-specific conditions. What used to require a manual trawl through council documents or a paid planning report now takes seconds. No waiting. No paid consultants. No surprises. Your team confirms viability before any design investment is made, and customers get clear answers the same day they ask.

uDrew Studio

Design with Built-In Compliance

uDrew Studio turns feasibility intelligence into a compliant granny flat layout. Design the dwelling, adjust size and positioning, and get live feedback on whether every change stays within the relevant planning rules. When the layout is finalised, the council-ready documentation is already prepared, with no separate compliance review, no additional formatting, and no extra steps.

Questions We Hear

Everything you need to know about site planning, compliance, and how uDrew fits into a Granny Flt or Modular Home business.

Yes. Every design built in uDrew Studio is validated against current planning rules as you work, and Studio includes all the design tools you need to produce professional, scaled plans without drafting experience. When the layout is finalised, the documentation exports correctly formatted for councils and certifiers, with no professional redrawing required.

Yes. uDrew OnSite automatically reports the constraints most likely to affect secondary dwelling installation: boundary setbacks, setbacks from primary structures, easements, zoning overlays, lot size thresholds, and coverage rules, using live data for the specific property. Those constraints carry directly into uDrew Studio, so as you adjust the granny flat layout, you're alerted the moment the design intersects with something that matters.

By confirming site constraints and compliance information upfront, uDrew catches the issues that normally trigger resubmissions before the design even begins. For granny flat installers, that's the difference between installations starting this quarter and waiting until next. Plans submitted to council are accurate the first time, which means fewer revisions, fewer follow-up questions, and installations that stay on schedule.

Most planning tools handle one part of the workflow. uDrew connects site feasibility, compliant design, and customer-facing presentation in a single platform. But that's only part of the story. uDrew instantly calculates the site engineering and design criteria that normally take days and thousands of dollars to commission, geotechnical conditions, site classifications, wind ratings, corrosion categories, AHD ground levels, and utility depths. No waiting on engineers. No assumptions about ground conditions. No quotes that blow out when installation day arrives. Everything you need to confirm, design, and quote, the moment you enter an address.

Granny flat customers spend weeks researching before they make contact. uDrew Connect captures that early interest and converts it into sales-ready leads. Connect Live lets customers place a granny flat design on their own property from home, giving them the confidence to enquire. Connect Display turns expo stands and showroom demos into closing conversations. By the time your sales team picks up the phone, the customer has already done most of the convincing.
