Make it yours

The Soho is drawn from our certified Passive House in Lilyfield, an Inner West home on a narrow block with a 2.9 metre fall and a large protected tree anchoring the front boundary. Rather than fight the site, the design steps down with the slope, so the levels follow the land instead of forcing a cut-and-fill battle.

It is a 260 sqm layout with four bedrooms, room for studies, and a double-height living void that draws the protected tree into the heart of the home. The Passive House modelling, healthy material choices and consultant coordination are already resolved. From there, we modify the plan to suit your block, your orientation and the way you live.

Why it matters

What the Soho means for your family

A certified Passive House is not about specifications. It is about how the home feels to live in, every day.

01

Clean, filtered air all day

A heat recovery ventilation system delivers a constant flow of fresh, filtered air, so your family breathes easy even with the windows shut.

02

A dry, mould-free home

An airtight, well-insulated envelope keeps humidity in check, protecting your family and the home from damp and mould.

03

Comfortable in every season

Stable temperatures of 20–25°C all year, with no cold corners in winter or stuffy rooms through a Sydney summer.

04

Up to 80% lower energy bills

The envelope does the heavy lifting, so heating and cooling barely run. Low, predictable running costs year after year.

05

Quiet, calm interiors

The same airtight build that saves energy keeps street and neighbour noise outside, where it belongs.

06

Certified and future-proofed

Independently certifiable to the Passive House standard, protecting your family's health and the home's resale value.

Proof, not promises

See it before you build it.

A real example from our Marvel Homes 360 method, not the floor plans shown above. Every tender we present includes a 3D render built from the exact materials in your contract, never stock imagery. Switch between one of those pre-construction renders and a 3D scan of the finished home, then drag through each to see how true to form we stay.

Site suitability

Designed for a narrow, stepped inner-west lot

Inner West and inner-city blocks come with real constraints: narrow frontages, steep falls across the site, heritage streetscape controls and protected trees. The Soho is engineered around exactly that. A stepped, split-level section turns a 2.9 metre fall from a problem into usable, light-filled space, while tight setbacks and roofline limits are resolved to the Passive House standard from the first sketch.

Where a protected tree anchors the boundary, we design with it rather than around it. At Lilyfield, a full-height glazed void frames the gum tree, so the tree that began as a planning constraint became the centrepiece of the entry. We manage the slope, the certifier and the council so you get an airtight, filtered, comfortable home that costs a fraction to run.

Common questions

  • Initial quotes can be vague, so we offer feasibility proposals instead. A project's success starts in the early stages, so this approach protects your time and investment from the beginning. Enquire to get started.
