New Home Design: 155.3SB – A Smart 3 Bedroom House Plan for Narrow Lots
Finding a home design that works well on a narrow block can be difficult. You still want comfortable bedrooms, good living areas, outdoor entertaining space and practical parking — without making the home feel cramped.
This week we're introducing our new 155.3SB Narrow Lot House Plan, a practical 3-bedroom family home designed to make excellent use of a block only 7.9 metres / 26 feet wide.
With a modern open-plan layout, three bedrooms, two bathrooms, alfresco area and single carport, this is a design worth considering for anyone building on a smaller or narrower block.
Ask the Builder: Can You Build a Comfortable Family Home on a 26ft Wide Block?
Yes — but the floor plan needs to be designed carefully.
One of the biggest mistakes I see with narrow homes is trying to squeeze a conventional wide house plan onto a narrow block. This can create wasted hallways, poorly positioned rooms and living areas that feel confined.
The 155.3SB takes a different approach. The home is designed around the narrow footprint from the beginning, allowing the important living spaces to remain open and functional.
155.3SB at a Glance
The design includes:
3 Bedrooms
2 Bathrooms
Master bedroom with ensuite and walk-in robe
Open-plan kitchen and dining
Separate living area
Kitchen with island bench
Separate laundry
Covered alfresco entertaining area
Single carport
117 m² / 1,259 sq ft living area
155.3 m² / 1,671 sq ft total area
Approximately 7.9 m / 26 ft wide
Approximately 18.2 m / 60 ft long
Designed Around Everyday Living
Although this is a relatively narrow home, the design doesn't try to fit too many separate rooms into the available space.
Instead, the kitchen, dining and living areas work together to create a more open central part of the home.
The kitchen includes an island bench that provides additional preparation space while also helping connect the kitchen with the dining area.
For smaller homes, this type of open arrangement can make a considerable difference to how spacious the house feels.
Three Bedrooms Without Wasting Space
The home provides three proper bedrooms.
The master suite is positioned toward the front of the home and includes its own ensuite and walk-in robe.
Bedrooms 2 and 3 are positioned toward the opposite end of the house, close to the main bathroom.
This provides some separation between the main bedroom and secondary bedrooms while avoiding excessively long hallways.
Indoor-Outdoor Living
One feature I particularly like about this design is the covered alfresco area positioned directly alongside the main living and dining zone.
For a smaller home, outdoor living can effectively become another living space.
Add an outdoor table, barbecue and comfortable seating and the alfresco area can become one of the most frequently used parts of the home.
A Practical Alternative to a Garage
Instead of using valuable floor area for a fully enclosed garage, the design incorporates a single carport.
For a narrow block this can be a sensible solution.
It provides covered vehicle parking while helping keep the overall house footprint relatively compact.
depending on your site and local building requirements, buyers could also investigate modifying the carport or changing the parking arrangement to better suit their property.
Who Could This House Plan Suit?
The 155.3SB could be particularly suitable for first-home buyers, couples, smaller families, downsizers, investors and people building on narrow urban blocks.
It may also appeal to buyers who would rather spend their building budget on usable living space instead of building an unnecessarily large home.
Ask the Builder: Are Smaller Homes Cheaper to Build?
Not automatically.
The number of square metres is important, but the complexity of the design can have just as much influence on building costs.
Multiple rooflines, complicated structural details, excessive corners and expensive finishes can quickly increase the cost of a smaller home.
That's why relatively straightforward designs such as the 155.3SB can be worth considering when you're trying to control your budget.
A simple, well-planned home can often give you more useful living space for your money than a complicated design of a similar size.
Start With Concept Plans Before Spending Thousands
One of the reasons we offer affordable concept house plans is to allow people to investigate a design before committing to expensive construction documentation.
The 155.3SB Concept Plan Package includes the builder's concept floor plan and elevations, 2D and 3D floor plans, front 3D render, dimensions and building areas, together with a copyright release allowing the design to be used for building.
You can use the concept design to discuss the project with builders, investigate preliminary pricing and determine whether the home suits your site and budget.
If you decide to proceed, the design can then be modified or developed into full construction plans as required.
Building on a Narrow Block? Don't Dismiss It
A narrow block doesn't necessarily mean you need to compromise on comfortable family living.
The important part is selecting a house plan specifically designed to work with the available width.
At only 7.9 metres / 26 feet wide, the new 155.3SB 3 Bedroom Narrow Lot House Plan demonstrates how three bedrooms, two bathrooms, open living, outdoor entertaining and covered parking can all be incorporated into a relatively compact design.
