YOUR GUIDE TO SIDE BY SIDE DUPLEX DESIGNS: EVERYTHING YOU NEED TO KNOW

Choosing the right house plan is a big decision, especially when considering side by side duplex designs.

They’re growing in popularity for all sorts of reasons and there’s a lot to think about before you jump in.

Side by side duplex designs aren’t just about creating two homes on a single block, they’re about lifestyle, investment, and even multi-generational living.

DELVING INTO SIDE BY SIDE DUPLEX DESIGNS

Before diving into the specifics of architects and designs, it’s essential to clarify your personal vision and align it with the location of your site. Do you lean towards a modern design in a coastal waterfront location or a charming countryside retreat blending seamlessly with its natural setting?

A side by side duplex design puts two separate homes right next to each other, sharing a common wall.

Each unit has its own private entrance, yard, and often a garage. This is different from a dual living design, where the homes are more integrated.

Side by side duplex designs usually allow for separate titles, so you could potentially sell one unit while living in the other.

ADVANTAGES OF SIDE BY SIDE DUPLEX DESIGNS

Side by side duplexes offer several advantages, making them appealing to both homebuyers and investors alike. Perhaps you are an empty nester or have older parents. Maybe you are an investor wanting to capitalise on your money. Let’s look at why side by side duplex designs are becoming a popular choice:

INCREASED LIVING SPACE

Two homes on one lot – it’s an obvious space maximiser. Great for larger families, flexible living spaces or blended families wanting independent space while remaining close. This also allows for more garden space compared to multi-story options.

POTENTIAL INVESTMENT OPPORTUNITY:

This is where things get interesting. You could live in one unit and rent out the other, generating passive income right from the start. Alternatively, rent out both sides, making a double return. Or even, live in one now, rent the other out to cover some mortgage costs and sell it later when property values have gone up.

AFFORDABILITY:

Purchasing a single plot of land and building two units can be more cost-effective than buying two separate properties. This makes entering the market easier. Construction costs can be lower when building two units at once due to bulk discounts, streamlining processes and potentially needing only one set of approvals.

FLEXIBLITY & CUSTOMISATION:

From choosing single or double storey units, corner block duplex or a more traditional design, each side of the duplex can be designed for the people living in them. While there is an option for different layouts, a popular approach is to have identical layouts providing efficiencies with construction and location of services

Different treatments of each facades is common to ensure each duplex is unique. Responses to the particular site constraints like the irregular shape of a block or the topography are also factors which can influence the design outcome and whether there are some variations between dwellings.

DESIGN CONSIDERATIONS FOR SIDE BY SIDE DUPLEX DESIGNS

Getting side by side duplex designs right means a balance between aesthetics, function, and respect for the neighbourhood’s existing character. Think carefully about the following when embarking on a project:

PRIVACY:

Living so close to your neighbours, even when it’s family, needs careful privacy planning. Think about window placement to avoid overlooking issues. Strategically placed fencing and landscaping can make all the difference in ensuring both residents feel like they have their own personal space.

House plants can also contribute to privacy as well as look good.

NOISE:

The common wall can transmit sound, so ensure proper acoustic insulation is used. Use materials designed to dampen noise transfer between units. Think about lifestyle differences too, such as music tastes, early rising children or working from home considerations and how this might impact those in the adjacent home.

OUTDOOR SPACE:

A shared driveway might be needed, depending on the lot. Each unit should still have its own dedicated yard area for some individual space to relax. Ensure appropriate landscaping solutions to define individual yard areas, without compromising aesthetic cohesion.

IS A SIDE BY SIDE DUPLEX RIGHT FOR YOU?

As with any housing option, it’s essential to weigh up the pros and cons based on your specific circumstances.

Some of the challenges to consider include the planning and council approvals process, which can be time-consuming depending on local regulations.

While a duplex offers significant advantages over owning two completely separate properties, there is a lack of total privacy compared to stand-alone dwellings.

For those seeking more than just a place to live, side by side duplex designs present an opportunity to diversify living arrangements.

BUILDING A DUPLEX STARTS WITH CHOOSING THE RIGHT BLOCK OF LAND

Snagging a great block of land is the first step to bringing your side by side duplex vision to life. But what makes a block perfect for this kind of build?

It’s about more than just the size – it’s about how the land lends itself to a dual living design.

ORIENTATION:

First, consider the orientation. We want to make sure both homes soak up the sunshine, especially if you’re dreaming of beachside living or a relaxing rural escape.

North-facing blocks are ideal, but a clever design can make the most of any aspect.

LAND SIZE AND SHAPE:

Next, we’ll look at the shape and slope of the block. A wider block can easily accommodate two homes side-by-side, giving each dwelling its own street presence.

If you’re working with a narrower or sloping site, don’t worry. We can explore split-level designs or get creative with landscaping to create privacy and visual appeal.

COUNCIL REGULATIONS:

Each council will have specific requirements regarding setbacks, building heights, and the minimum lot size for a duplex. These regulations often vary so research this early in the piece.

UNDERSTANDING YOUR DUPLEX MARKET: DESIGNING FOR DIFFERENT NEEDS

When considering the layout and design of your duplex, it’s advisable to consider your target market or the needs of those occupying the dwellings.

For instance, are you catering to small families, downsizers, or multigenerational families?

This will influence your choices regarding bedrooms, bathrooms and living areas. A well-designed floor plan can optimise flow and functionality. It can also incorporate clever storage solutions to maximise space utilisation.

Once the practical aspects are taken care of, it’s time for the fun part. Choosing your desired interior and exterior finishes. This is where you can really personalise each unit. From flooring to paint colours and fixtures, the options are endless.

You may also want to think about things like landscaping, which can significantly enhance street appeal and create welcoming outdoor spaces. Don’t forget to check out potential display homes in your area to gain inspiration.

Side by side duplex designs are gaining popularity because they offer a fantastic solution for many.

Building a duplex is more complex than a single-family home, and there will be a higher initial investment, but a duplex also provides increased value over time and potential income.
