A well-built extension changes the way a home works — adding a bedroom for a growing family, a larger open-plan living area, or a connected indoor-outdoor space that makes the home genuinely more liveable. What it requires to achieve that properly is more than carpentry: it involves structural engineering assessments, building permits, council planning where required, coordination of trades (concrete, framing, roofing, electrical, plumbing), and consistent project management throughout. EVN Construction manages extensions as integrated building projects rather than loosely coordinated tasks — Evan is on site through the key stages rather than managing by phone. With 10 years of construction experience across Melbourne's north east, EVN brings practical knowledge of local council requirements, common site conditions, and the realities of building while a family is living in the home.



The permit process is one of the most misunderstood aspects of building an extension, and getting it wrong is expensive. In Victoria, a building permit is required for the vast majority of home extensions and must be obtained through a registered building surveyor before work starts. For homes in Nillumbik Shire (Diamond Creek, Eltham) or properties with heritage or green wedge overlays, additional planning permits from council may also apply. EVN Construction advises on permit requirements at the quoting stage and can refer you to appropriate surveyors and engineers as needed. Building without the right permits creates problems when you sell the property and can require expensive retrospective rectification. EVN Construction builds to code from day one so your investment is protected long after the project is complete.

Every extension project at EVN Construction starts with an in-person consultation where Evan reviews the site, understands what you're trying to achieve, and works through any constraints — block size, council setbacks, existing structure, services. A quote is prepared and reviewed with you in detail before anything is confirmed. Permits are obtained with the correct professionals, and a construction timeline is agreed so you know what's happening and when. Evan manages the site directly throughout the build, with clear communication at each milestone. Structural work, framing, cladding, roofing, and finishing are all co-ordinated through EVN Construction rather than handed to separate subcontractors you've never met. Final inspection confirms everything meets code before the site is handed over clean. Call 0435 152 008 to begin your extension conversation.

EVN Construction is based in Doreen — 11 Weaver St — which means when you call Evan for a renovation, deck, pergola, or home maintenance job in Doreen, he's already in the suburb. Most of Doreen's housing stock has been built since 2000 across estates like Laurimar and Edgars Creek, which means large backyards with real potential for decks, pergolas, and verandahs, and homes that are now reaching the age where first major renovations make financial sense. EVN Construction has delivered carpentry and renovation work throughout Doreen's estates and knows the property types and local building requirements well.

Bundoora's housing stock spans several decades — from 1970s and 1980s brick homes on larger blocks through to more recent developments near La Trobe University. EVN Construction serves homeowners across Bundoora with renovations, extensions, decks, pergolas, verandahs, and home maintenance, bringing 10 years of carpentry experience and $20 million public liability insurance to every job. Older Bundoora homes often present renovation opportunities that newer homes don't — bigger blocks, solid construction, and layouts that can be genuinely transformed by well-planned extensions or full room renovations. Evan attends every job personally and provides transparent, upfront pricing.

Diamond Creek sits in Nillumbik Shire — a council area with specific planning overlays, heritage considerations, and green wedge zoning that affect what can be built and how. EVN Construction serves Diamond Creek homeowners with renovations, extensions, decks, pergolas, verandahs, and home maintenance, and is familiar with Nillumbik's permit requirements. Many Diamond Creek homes were built in the 1970s and 1980s on generous blocks, creating real opportunity for renovations, extensions, and outdoor living structures. Evan Lanza provides transparent quoting, manages permit requirements honestly, and attends every job personally.

Eltham is one of Melbourne's most distinctive suburbs — a community built around character, creativity, and a strong connection to the natural environment. Many Eltham homes are mudbrick, mud and timber, or heritage character properties on large leafy blocks, and they require a different approach to renovation and carpentry than the standard brick veneer estate home. EVN Construction serves Eltham homeowners with renovations, extensions, decks, pergolas, verandahs, and maintenance — bringing both carpentry skill and an understanding of Nillumbik Shire's planning environment, including the heritage and green wedge overlays that affect what can be built in Eltham.

Greensborough is an established north-eastern suburb with a strong residential character — a mix of 1960s and 1980s brick homes, newer estate development, and generous block sizes that suit outdoor building projects well. EVN Construction serves Greensborough homeowners with renovations, extensions, decks, pergolas, verandahs, and home maintenance. Greensborough sits within Banyule City Council's area and EVN Construction is familiar with local permit requirements. Whether you're upgrading an older Greensborough brick home, building a new deck on a generous block, or tackling a maintenance list that's been growing for three years, Evan attends personally with transparent pricing.

Heidelberg has one of Melbourne's north-east's richest residential characters — homes from the 1920s through to the 1960s on tree-lined streets, with the Austin Hospital and Burgundy Street corridors anchoring the suburb's identity. Many Heidelberg homes have been in families for decades and are now undergoing their first serious renovation. EVN Construction serves Heidelberg homeowners with renovations, extensions, decks, pergolas, verandahs, and home maintenance, bringing careful workmanship and genuine respect for older properties. Banyule City Council permits are handled at the quoting stage, and Evan attends every job personally.

Macleod is a quiet residential suburb in Banyule's north-east — predominantly 1960s and 1970s solid brick homes on comfortable blocks, with a community character that values the local and the reliable over the flashy. EVN Construction serves Macleod homeowners with renovations, home maintenance, decks, pergolas, verandahs, and extensions. The suburb's older housing stock creates consistent demand for renovation and maintenance work, and the block sizes on many Macleod streets support outdoor building projects well. Evan attends personally, quotes transparently, and completes work to a professional standard with full clean-up.

Mill Park's residential streets hold a mix of properties: 1980s and 1990s brick homes on generous Plenty Road-area blocks, newer estate development near Westfield Plenty Valley, and the characterful older homes on the suburb's original streets. EVN Construction serves Mill Park homeowners with renovations, extensions, decks, pergolas, verandahs, and home maintenance — with Whittlesea City Council permit requirements managed at the quoting stage. Whether it's a first major renovation on a 30-year-old family home or a deck addition on a newer estate property, Evan attends personally and provides straight-talking, transparent service.

Rosanna is an established middle-ring suburb in Banyule's north-east — leafy streets lined with solid brick homes built primarily in the 1950s through to the 1970s, and a residential community that values quality and character. Many Rosanna homes have been in families for extended periods and are reaching the point where genuine renovation investment makes strong financial and lifestyle sense. EVN Construction serves Rosanna homeowners with renovations, extensions, decks, pergolas, verandahs, and maintenance — Evan attends personally, understands older property conditions, and provides transparent, detailed quoting. Banyule City Council permits are managed correctly from the quoting stage.

South Morang is one of Melbourne's north-east's most active growth corridors — estates built largely post-2005 along the Mernda rail line extension, with large blocks, young families, and homes that are now reaching the age where first major renovations and outdoor structures make sense. EVN Construction serves South Morang homeowners with renovations, extensions, decks, pergolas, verandahs, and home maintenance. The suburb's newer housing stock is well suited to deck and outdoor structure additions in large backyards. Whittlesea City Council permits are managed at the quoting stage, and Evan is based in neighbouring Doreen — close and familiar.

Thomastown's residential streets carry decades of history — 1960s weatherboard homes, 1970s and 1980s brick veneer, and a community that's seen significant change as the industrial corridor transitions and the suburb's demographics shift. EVN Construction serves Thomastown homeowners with home renovations, maintenance, extensions, decks, pergolas, and verandahs. Older homes in Thomastown present strong renovation potential: solid construction, larger blocks in many streets, and kitchen and bathroom layouts that haven't been updated since original construction. Evan attends personally and brings honest, practical advice to every project.

Watsonia is an established north-eastern suburb with a quiet residential character — post-war homes on comfortable blocks, a community that values reliability and workmanship, and a property landscape that holds real renovation and outdoor building potential. EVN Construction serves Watsonia homeowners with renovations, extensions, decks, pergolas, verandahs, and home maintenance. The suburb's post-war homes (1950s-1970s) are at the natural renovation cycle point, and Banyule City Council permits are managed correctly at the quoting stage. Evan attends every job personally.
Home extension costs in Victoria vary based on the size of the addition, whether a second storey is involved, and the finish level required. A modest ground-floor rear extension typically starts from the mid tens of thousands upward; a second-storey addition is generally more costly due to structural engineering and roofing work. EVN Construction provides a detailed quote after a site inspection — call Evan on 0435 152 008 to discuss your extension and get an honest estimate based on your specific situation.
Almost all home extensions in Victoria require a building permit obtained through a registered building surveyor. Larger additions or those close to property boundaries may also require planning approval from your local council — whether that's Whittlesea, Nillumbik, or Banyule council depending on your suburb. EVN Construction will advise at the quoting stage exactly what approvals your project needs and can connect you with the right professionals to get them. Getting permits right before work starts protects your investment and avoids expensive compliance issues later.
A straightforward ground-floor rear extension typically takes six to twelve weeks on site once permits are in place. Permit approval itself can take several weeks depending on council and building surveyor workload, so the total timeline from first conversation to completed build is usually three to six months. Second-storey extensions take longer due to structural complexity. EVN Construction provides a realistic build timeline at the quoting stage, and Evan communicates directly throughout so you're always up to date on progress and what's coming next.
In most cases, yes — particularly for rear or side extensions that don't affect the main living areas of the home until late in the build. There will be periods with noise, dust, and limited access to parts of the house, and Evan will brief you on what to expect at each stage before it happens. For second-storey additions, temporary roof exposures may require brief periods of more significant disruption, and EVN Construction plans for these carefully to minimise inconvenience. The staging plan is explained in full before work starts so you can make informed decisions about your living arrangements.
