“Open it up” sounds like a clear renovation brief until the drawing has to show which walls go. A wider connection may make conversation easier and bring the kitchen into view. It may also remove the only useful place for a cabinet, cut through an older ceiling or require support that changes the room again.
For a Mont Albert home, we would make the amount of wall removal a deliberate design decision. Draw several degrees of opening, understand the existing construction and judge the resulting rooms before committing to demolition.
Read the actual house before drawing a large opening
Whitehorse's Mont Albert Residential Precinct guidelines describe substantially intact Victorian, Edwardian and interwar houses. They distinguish symmetrical timber villas, larger asymmetrical Edwardian homes and bungalow forms. Those differences matter: a wall in an already generous villa may serve a different purpose from one separating several compact rooms.
The same guide records details including grouped windows, window hoods and verandahs. We would measure the actual openings and record surviving details before placing a new connection. An opening should work with where daylight already enters, rather than assume that every older room needs a new external window.
These observations concern a defined precinct, not every Mont Albert address. Establish the relevant council, current heritage status and significance of the particular building. The council's older precinct guidance is useful context; current property information and appropriate advice must determine what work is possible.
Compare three versions of the same connection
Begin with the existing doorway. Would moving a door swing, changing a room's fittings or making a nearby opening do enough? This is a useful comparison even when it proves insufficient: it shows what the larger intervention must improve.
Then draw an enlarged opening with wall remaining at each side. It could connect a kitchen and sitting room while leaving a clear edge to each space. The remaining wall might hold a light switch, artwork or a piece of furniture. Check the opening's position as carefully as its width; a generous connection in the wrong place can put movement through the middle of the seating.
Finally, draw the near-complete removal of the dividing wall, with any necessary supports shown. This may create a more useful shared room. Compare it honestly with the smaller opening: does the extra width allow a better arrangement, or mainly expose more of the kitchen from every seat?

Let the structural investigation change the sketch
A wall's thickness or appearance does not establish what it supports. We would seek structural advice on the roof, ceiling, floor and any upper construction before treating a proposed opening as straightforward. Earlier alterations may also affect how loads are carried.
Ask how the opening would be supported at its ends as well as above. A beam may need posts and suitable foundations; concealing it within the ceiling may have different implications from showing a change in ceiling height. The engineer's findings should inform the architecture while the position and extent of the opening can still move.
Discuss construction access, temporary support and the protection of retained finishes with the design and building team. A neat line on a plan can involve work beneath the floor or through an occupied room. Early cost advice can help compare that intervention with another way to achieve the same improvement.
Draw the wall that remains, not only the gap
Use an elevation of each affected room to show the opening, cornice, skirting, fittings and furniture together. A narrow remnant of wall may be too small to do anything useful; a considered pier can give the room an edge and make the new opening feel intentional.
Look at the ceiling too. An existing cornice should have a resolved stopping point where a new opening interrupts it. Floors may need repair where a wall is removed, and matching old boards exactly may be difficult. Decide where an honest change of material would be preferable to an uncertain patch.
Preserve the usefulness of the existing windows. A new kitchen cupboard, tall storage unit or structural post should not casually cover an opening that gives the room its proportion and light. Where work changes a street-facing opening, investigate its heritage implications specifically.
Decide what still needs more space
An internal opening can improve how rooms relate without providing another bedroom, a larger bathroom or more garden-facing floor area. Separate those needs. If an addition is still required, the earlier study gives it a clearer brief and identifies the connection it actually needs.
A retained wall and a measured opening may work well with a modest extension; another house may justify broader reorganisation. For a new home, use the same discipline to decide which activities should share one space and where a defined room or substantial wall would help. Open space should be designed around use.
Bring benssur an existing plan and photographs showing both sides of the walls you hope to change, including the ceilings and windows. We can compare internal renewal, an extension and, where appropriate, a new-home direction with a clearer account of the work and benefit of each.
