Product strategy
Framing the journey from first enquiry to the day the keys change hands.
Sample concept · Real Estate & Construction
SiteLine
A real-estate and construction app that carries a home from listing to handover. Buyers browse units and enquire, then follow live site progress from a buyer portal, while a document vault and handover checklist keep the paperwork straight. A sample concept — designed for iOS and Android.

SectorReal Estate & Construction
An illustrative concept — a sample case study showing how we'd approach Real Estate & Construction, not a delivered client project.
The context
A home is bought long before it is built.
Buyers commit to a property months — sometimes years — before they get the keys. In that gap they are largely in the dark: a deposit paid, a build they can’t see, and updates that arrive only when they chase an agent for them.
SiteLine imagines that whole stretch inside one app. Browse and enquire, then sign in to a buyer portal where progress photos, milestones, documents and messages all live in one place — for the buyer and the developer both.
The challenge
Hold months of a project in one calm view.
Property is a high-value decision on a long timeline, touched by people on very different clocks — a buyer checking in from the sofa, a site team logging photos in a half-built stairwell, a sales team fielding the same question a hundred times.
So the concept had to hold a lot of context — listings, milestones, documents and photo proof — without ever feeling heavy. The aim: an app that reads as one clear next step at a time, and is still right on handover day.
Skills
What we'd bring to it.
UX / UI design
Flows, wireframes and a calm interface for a decision people make once in years.
Prototyping
Interactive prototypes to pressure-test enquiry, portal and progress flows.
iOS & Android app
One native-quality product concept designed for both platforms.
Property & site UX
Listings, milestones and site photos shaped for buyers and developers alike.
Design system
A shared blue colour, type and component system across every screen.
In the concept
Six things, one property app.
Property listings
Browse available units with plans, galleries and pricing, so a buyer can shortlist a home before they ever pick up the phone.
Enquiries & bookings
Send an enquiry or book a show-unit viewing in a tap, with the request landing straight in the developer’s pipeline.
Buyer portal
A logged-in home for each purchase — status, payments and messages in one place, so every party sees the same live picture.
Live site progress
Date-stamped construction photos and milestones from the ground, so buyers watch their home take shape instead of chasing updates.
Document vault
Contracts, floor plans and approvals stored, versioned and searchable — still findable months after handover.
Handover checklist
A guided snag-and-sign-off flow for the final walkthrough, so nothing is missed on the day the keys change hands.
Under the hood
Designed for the long haul.
The screens are simple; the timeline behind them is not. The concept assumes a purchase that lives for months — accruing photos, milestones and documents — captured out on real sites where the signal is patchy and the light is bad.
One purchase, one thread
Every buyer’s status, payments, documents and messages tied to their unit in one place.
Date-stamped site photos
Progress captured on the ground and pinned to milestones, not lost in a chat thread.
Connectivity-tolerant
Site and inspection screens designed to queue uploads through the dead spots of a build.
Versioned document vault
Contracts, plans and approvals stored and versioned so the right file is findable later.
Guided handover
A snag-and-sign-off checklist that walks the final inspection step by step.
Native iOS & Android
One product concept, both platforms, one design system.

“From the first viewing to the day the keys change hands — one app that holds the whole build.”
Design system
One blue, a lot of clarity.
A single confident blue marks every step — enquire, follow, approve, hand over — against clean white lists, so months of a project read as one clear next thing to do.

Buyers watch their home take shape from their phone, and the developer answers “where’s my unit at?” once, in the app, instead of a hundred times by email.
FAQ
About the concept.
What is SiteLine?
SiteLine is an illustrative concept for a real-estate and construction app — a sample case study, not a delivered client project. It shows how Namtech would approach property listings and enquiries, a buyer portal, live construction-progress photos and milestones, a document vault and a handover checklist, designed for iOS and Android.
What did Namtech build for SiteLine?
SiteLine is a design concept produced to demonstrate our approach. It sets out the whole product: property listings, enquiries and show-unit bookings, a logged-in buyer portal, date-stamped site-progress photos and milestones, a versioned document vault, and a guided handover checklist — unified by a single design system across both platforms.
Can buyers follow their home being built inside the app?
Yes — that is the heart of the concept. The buyer portal pairs each purchase with date-stamped construction photos and milestones, so buyers can watch their home take shape from their phone, and the developer answers “where’s my unit at?” once in the app instead of a hundred times by email.
