Sydney hands out some genuinely difficult sites. Narrow blocks, inner-city terraces, steep sloping lots on the Northern Beaches: these are the kinds of projects that reveal whether a designer is thinking or just drawing. On a tight site, every decision matters more. There’s no room to hide an awkward proportion or a poorly placed wall.
But there’s something else that’s true about narrow blocks: when they’re handled well, they tend to produce some of the most satisfying homes you’ll ever walk through. The constraints force a rigour that more generous sites don’t demand. You can’t rely on space as the answer to every problem, so you have to find better answers.
Landart’s Lakeside House project is a good example of what a narrow block can become. On a site that could easily have felt pinched and dark, the house is genuinely expansive: tall, light, and connected to the garden throughout. The design decisions that made this possible apply far beyond this single project.
Orientation is everything on a tight site
On a wide block, you have options. You can place living spaces in multiple positions and still catch good light. On a narrow block, especially in Sydney’s suburban grid, you often have one chance to get the orientation right, and if the lot runs north to south, you need to work much harder.
The Narrabeen house faces north along its long axis. This is the design decision that makes everything else work. North-facing glazing across the full length of the home means every main room catches the low winter sun, while the eave depth keeps out the high summer sun before it hits the glass. The house is warm in winter without heavy heating and cool in summer without the need for Air Conditioning. The orientation does the work.
If you’re working with a block where this isn’t possible, where the long axis runs east to west, the design response changes but the discipline doesn’t. You compensate with carefully placed skylights, light wells, double-height spaces, and material choices that reflect and carry light deeper into the plan.
Think vertically
A narrow block doesn’t give you horizontal spread, so good design uses the vertical dimension instead. This means thinking seriously about ceiling heights, floor level changes, voids, and the relationship between levels.
In the Lakeside House, the north side of the home grows taller as you move through it. The kitchen and sunken lounge on the south side are more enclosed: lower, darker, more grounded. Move toward the planted beds along the north wall and the space opens up with taller ceilings, more glass, more sky. The change in scale as you move through the home gives it a sense of journey that a uniformly proportioned plan never achieves.
A sunken floor level in one zone, a double-height void in another, floating stairs that don’t block sightlines: these are what make a narrow home feel generous. They cost more to execute than a flat-ceilinged box, but they’re the difference between a home that feels constrained by its site and one that feels liberated from it.
Bring the outside in (and mean it)
On a wide block, the garden is over there. On a narrow block, the relationship between inside and outside has to be more fundamental, or the house simply feels small.
The single most distinctive decision in the Lakeside House is the continuous planted bed that runs the full length of the north wall behind floor-to-ceiling glass. Every room in the home looks into greenery. You’re always in proximity to the garden, regardless of where you are in the plan. The boundary between interior and exterior is, in effect, just glass.
This isn’t decorative. It’s spatial. The planted bed gives every room a visual depth it wouldn’t otherwise have. It makes a narrow room feel open in a way that a view of a fence or a boundary wall never could.
At Narrabeen, timber boardwalks connect the driveway, garage, and front door, giving the arrival experience warmth and purpose rather than a blunt transition from street to house. On a narrow block, entry sequences matter more than on a wide one, because you can’t use a grand forecourt or a sweeping driveway. You work with what you have, and you make it deliberate.
Materials do more work
On a tight site, material choices contribute to the perceived size of a space in ways that don’t apply the same way on larger plans.
Reflective surfaces (tiles that catch light differently in the morning than in the afternoon, polished stone that carries brightness further into a room) add apparent depth. Light-coloured flooring on a lower level helps bounce light up into spaces that might otherwise feel shadowed. Limestone below, hardwood above: the change in material reinforces the change in spatial character, and both choices age in ways that feel right rather than dated.
Curves matter on narrow sites too. Hard right-angle joinery in a narrow corridor emphasises the corridor’s narrowness. Curved joinery, rounded corners in cabinetwork, forms that soften the geometry of the room: these take the edge off what is, structurally, a confined plan. The Narrabeen house uses curves throughout the interior for exactly this reason.
| Design challenge | Response that works |
| North-south block orientation | Maximise north glazing; use skylights and voids for east-west compensation |
| Low natural light in southern rooms | Reflective materials, light wells, pale flooring, carefully placed mirrors |
| Rooms feeling narrow or boxed | Vary ceiling heights, use curves in joinery, align views to planted beds or sky |
| No room for a traditional garden | Continuous planted beds inside the building envelope, green roofs, vertical planting |
| Entry feeling abrupt or mean | Design a deliberate arrival sequence: boardwalk, material change, planting, threshold |
| Two-storey connection feeling severed | Floating stairs with open risers, voids, sightlines between levels |
The landscape holds it all together
On a narrow block, the landscape design can’t be saved for the end of a project. It has to be thought about at the same time as the building, because on a tight site the two are inseparable.
At Narrabeen, the charcoal-stained weatherboard cladding and green roof bring the building back into the Northern Beaches landscape it sits within. The coastal planting (grasses, mounds, seasonal flowers) softens the concrete and gives the exterior the same quality of layered character that the interior has. The building doesn’t try to contrast with its environment. It belongs to it.
This is the design ambition on any narrow block done well: a home that is fully itself on a site that might have made a lesser project feel apologetic. The constraint isn’t overcome. It’s used.
What to ask before you start
If you’re facing a narrow block and working out how to approach it, these are the questions worth having answered before any drawings are produced.
| Question | What the answer tells you |
| Which direction does the block face? | Determines passive solar strategy and where to locate living areas |
| What are the setback and height requirements? | Sets the envelope you’re working within before design starts |
| Where does natural light come from at different times of day? | Informs window placement, room orientation, skylight positions |
| What’s the arrival sequence from the street? | Shapes the entry design and the sense of transition into the home |
| Can the planted areas be inside the building envelope? | Determines whether biophilic design is a real option rather than a gesture |
| How will the two levels relate to each other visually? | Drives void placement, stair design, and the sense of spatial connection |
A narrow block is not a compromise. In the right hands, it’s a brief. And some of the best homes we’ve seen and built have come from sites where space alone couldn’t be the answer.
To see how these principles came together in practice, take a look at the Lakeside House in Narrabeen. And if you’re working through a similar challenge, talk to the Landart team. We work across Sydney’s Northern Beaches, North Shore, and Eastern Suburbs on homes where the site is part of the design.
