What if a wedding chapel let the landscape do the decorating? This giantA design study keeps the hilltop chapel and reception pavilion plain and material-led: an arched forecourt in bagged white brick with olive trees and the valley beyond, a nave of exposed timber A-frame trusses with roof light falling across empty timber pews, and a simple stone altar table set before a full-height window to green hills. A lime-rendered barrel-vaulted reception hall holds long bare timber tables and bentwood chairs over handmade terracotta tile, a brass and timber-post glass colonnade runs through native gardens and gums, and the walk ends on a lawn terrace at golden hour.

Shown empty, cut fast from forecourt to terrace. An imagined design study only, not a real, planned or commissioned venue.

What if the lodge sat in the canopy instead of clearing it? This Gold Coast hinterland-inspired concept raises a cluster of compact timber pavilions on stilts above the forest floor, so the creek, tree ferns and big trunks stay untouched below. Spotted gum battens filter the morning sun, a cantilevered walkway links the rooms, and low-iron glass opens each pavilion to the treetops, with a sunken fire on the deck for cooler mornings. The concept palette also explores rammed earth, weathered steel and hoop pine ply.

A giantA concept, imagined, not built, and not a real lodge.

What if a headquarters felt more like a garden atrium than a glass box? This giantA design study keeps the workplace material and planted: a double-height atrium under a timber-ribbed skylight with a sculptural sandstone blade, a long open workspace of bare Victorian-ash desks and chairs with no screens or clutter, and a full-height living green wall rising through an internal courtyard void. A curved timber boardroom holds a rough-hewn stone table, a terrazzo breakout lounge filters light through bronze-anodised perforated screens, and the walk finishes on a rooftop timber deck garden at golden hour.

Shown empty, cut fast from atrium to roof. An imagined design study only, not a real, planned or commissioned building.

What would a classroom look like if the rockpools were the lesson? This Illawarra-inspired concept sets a marine education pavilion and research station on a basalt sea cliff, cantilevering a white off-form concrete teaching deck over the water. Illawarra basalt walls, recycled ironbark battens and weathered copper eaves keep the palette local and salt-tough, while low-iron glass pulls the ocean right into the gallery. Shorebirds work the rockpools at the start; inside, a lone researcher stands at the window; at the end a gull glides over the copper roof.

A giantA concept, imagined, not built, and not a real facility.

Before you lodge a new dwelling with a NatHERS simulation, run the same four checks your council or certifier will.

The NSW DPHI guide, BASIX Guide: Checking thermal performance for the Simulation method (May 2025), says the consent authority checks these at DA or CDC stage, and the certifying authority checks them again during construction:

1. Development details. Both a BASIX and a NatHERS certificate are lodged, and the address or lot details match across the plans, both certificates and the application.
2. The NatHERS certificate. It uses the correct template (individual dwelling or Class 2 summary), its QR code scans to the certificate you submitted, and the assessor and certificate numbers match the BASIX certificate.
3. The NatHERS stamp. Every relevant drawing, from floor plans and elevations to window schedules and insulation notes, carries a stamp whose details and QR code match the certificate.
4. Heating and cooling loads. The MJ/m².year figures on the BASIX certificate are the same as those on the NatHERS certificate.

If anything is inconsistent, the application goes back to the applicant. In our experience the stamp is where late design changes cause the most trouble, so freeze the architectural set, finish the NatHERS run, stamp the full package and then lodge.

Our guide covers each check, the approval stages they apply to and a step-by-step sequence before lodgement:

Penrith DA templates need updating. Since 1 October 2026, every chapter of Penrith DCP 2014 has a new number.

Amendment No. 18, endorsed by Council on 24 August, moved the old C, D and E chapters into a new B, C and D structure. Site planning is now B1, heritage is B4, and vegetation, water, land, landscape, noise and urban heat are combined into B5 Environmental Management. Waste is now B6, residential development sits in C2, and the key precincts moved from E to D, so St Marys Town Centre is now D15. The Sydney Science Park chapter has been removed, and the Western Sydney Aerotropolis DCP applies there instead.

The new waste chapter adds FOGO guidance. Residential FOGO collection becomes mandatory from 1 July 2030, and some non-residential premises are phased in from 1 July 2026. Bin areas need to fit a 140 L residual, a 240 L recycling and a 240 L FOGO bin for each dwelling.

On the LEP side, the Penrith LEP 2010 housekeeping review (PP-2025-2448) is with Parliamentary Counsel and must be made by 27 November 2026. The State-led Werrington rezoning has finished exhibition but has not been determined, so the existing controls still apply.

Our October digest has the full old-to-new chapter table, plus updates on Emu Plains, the Glenmore Park Stage 3 exhibition villages at Mulgoa and the Jamisontown heritage listing:

How do you make a penthouse feel calm when the view is doing all the talking? This giantA design study keeps the palette quiet and lets the water lead: a lift vestibule in honed charcoal basalt with brushed ch*****ne bronze doors, an open living room glazed floor to ceiling towards the harbour, and a sculptural basalt kitchen island left completely bare. A white-washed jarrah stair rises beside warm lime plaster, the main bedroom is wrapped in fluted pale-oak joinery, and the bathroom centres on a freestanding stone bath. The walk finishes on a wraparound terrace as the sun drops over the water.

Shown empty, cut fast from lift to terrace. An imagined design study only, not a real, planned or commissioned apartment.

What if a dark-sky observatory shared a roof with a visitor lodge on the red plain? This Pilbara-inspired concept stacks pindan sandstone and pale limestone under a floating verdigris copper canopy and dome, with cypress pine slats filtering morning light across polished aggregate concrete. Red kangaroos move through the spinifex at the start; inside, a lone hiker silhouette waits at the glass; at the end a wedge-tailed eagle rides the air over the dome on the gorge edge.

A giantA concept, imagined, not built, and not a real facility.

Designing a shop-top or podium building in NSW? Check how far the DBP Act reaches before you brief your consultants.

Under clause 12 of the Design and Building Practitioners Regulation 2021, a building is regulated if any part of it is Class 2. The Regulation's own example is a mixed-use building with Class 2, Class 5 and Class 6 parts, and it confirms the Act applies to the office and retail parts as well. NSW guidance adds that regulated designs are needed for all parts of a building with a regulated part, including work above a Class 7 carpark.

A few traps catch people out. A single dwelling in a shop or office building is usually a Class 4 part, which clause 12 doesn't list, but convert space into a second flat and both become Class 2, bringing the whole building into the scheme. Fit-out of a Class 5 or 6 part can be excluded when the development consent primarily relates to the fit-out, though only to the extent the work doesn't touch a structural component. And the low-rise registration condition stops at 2,000 m² gross floor area, while medium-rise allows four storeys only where the ground or first storey is a Class 7a carpark.

Our guide covers NCC classification, regulated designs for each building element, Planning Portal lodgement and registration limits:

What does a small hotel need to get right in the first thirty seconds? This giantA design study answers with materials: a pale Sydney sandstone porte-cochère under a walnut soffit, a double-height lobby with a solitary walnut reception desk on brass-inlaid terrazzo, and a spiral stair in walnut and brushed nickel. Upstairs, a curved corridor in soft sage plaster leads to a guest suite of walnut joinery and linen, with a vanity basin carved from solid sandstone. The walk ends on a rooftop terrace as the sun drops behind a distant skyline.

Shown empty, cut fast from arrival to rooftop. A speculative design study only, not a real, planned or commissioned hotel.
