Please Consider This

The undercroft house plans pictured here are homes we have designed specifically for our clients. While you can build these undercroft homes, they weren’t designed for you, your family or your particular site. While some of these undercroft designs may appeal to you, the home we actually design for you will be completely unique. Let’s chat about your new home today!

Lady thinking about undercroft house plans

Thinking about an undercroft home?

The most important factor to consider, when having undercroft home plans designed, is experience. There’s so much more to this than simply designing a house. An understanding of engineering principals is paramount to the success of undercroft home design. Without such knowledge and experience, the design and engineering process can prove very time consuming and expensive indeed. We’ll help you avoid this.

Then there’s council approval. No one likes to be bogged down with house plans that simply won’t get approved. Thanks to our knowledge & experience, this home was approved without a hitch.

We have the runs on the board. If you’re considering an undercroft home design, talk with us about your ideas.

What our Clients Say

From the people who really matter.

Boyd Design provided a professional service developing a bespoke house design for our steep block of  land. We had a challenging set of constraints and he worked with us to develop a design that would encompass our requirements and maximise the views.

Working with Boyd while we were living & working in China, our home was designed via email. As such, we really didn’t know what to expect. We were blown away by Boyd’s design.

Adrian, Bunbury.

All our friends with canal homes have really low ceilings in their undercroft areas. Right from the outset, Boyd said he’d never design a home with such low ceilings. He said he wouldn’t have a low ceiling, so why should we. He’s a man of his word!

Now everyone keeps asking how we achieved such a high ceiling level in the undercroft, combined with high ceilings to the other floor levels and such a high pitched roof at the same time!

Ashley, Halls Head.

We first me Boyd five years before we engaged his services. This was for a home addition design. Boyd was so honest, he advised against us undertaking the renovation because it wouldn’t add value to our home, he talked himself out of a job!

Now in our new home, we sat down and asked each other what we’d change about our house. Neither of us could come up with one single thing. Even the trades people were impressed!

Carolyn, Bedfordale.

When collecting their plans from the Council, the Council fellow said “We can’t fault these plans at all, everything is spot on. This has never happened before, you should hold on to this guy”.

This is testimony to the genuine passion we talk about. These are not just mere words, these are our DNA. No matter what Council and no matter how challenging the design, you can rest assured we will get it spot on.

City of Armadale

Boyd has exceptional interpersonal skills and constantly demonstrates that he understands our needs and wishes. He has proven to be patient and flexible beyond a fault.

Even when we changed our plans by purchasing the block next door Boyd was not fazed and started anew with a completely different plan, scope and outcome of the design. Exceptional client focus rarely seen in today’s world.

Kirsten, Exmouth.

When you said you’d get it right the first time, we just thought that was just part of your sales pitch. But you did just that and we’re absolutely blown away.

Sadly, things happen and not all our home designs get built. The reasons for this are numerous and life happens to us all. With an impressive undercroft area, the plans for this Coogee home attract attention from all over Australia.

Michael, Coogee.


When asked if they’d sell their home for a handsome profit, Tiffany replied… Sell it? No way, we love it. Everything about it just works so well for us.

This is another case where I originally met these lovely people to the renovation of their existing home. What they had in mind was not going to add value and I advised them against it. Kicking off with the renovation design, the seed grew and they eventually saw the light

Tiffany, Hillarys.

Boyd designed our new house from scratch, it is in the council approval stage now. I am very pleased I chose Boyd, he’s much more than an designer. He has an artistic mind and a great eye for detail which creates a wow factor for his designs.

The existing home, which was to be demolished, was the remains of a home which had been cut in two. Engineering was a nightmare, but nothing Boyd Design couldn’t overcome.

Ron, Bicton.

As a visual person, I have the ability to see my designs in my head before they are built. When look at my plans, some people often wonder why I design certain elements the way I do.

Early on, the bricklayer for a three storey home in Halls Head was asking himself why I had design certain elements the way I had, making his job more complex. Once the home was finished, he said “Now I can see why, it looks amazing”.

Bricklayer, Halls Head.

Common Questions Answered
about us

When shopping around for house designers for the design of your undercroft home, it’s only natural that you’ll have a ton of questions. You may be asking yourself “Who can I trust to design my home?”, “What if I don’t like the home they design?”, “How much does it cost?”, “Who builds the design?”

As experienced designers of undercroft house plans, we’ve successfully designed all types of undercroft homes for all types of people and all types of sites. As such, there probably isn’t a scenario we haven’t dealt with. In addition, our clients range from those who have never built before through to the directors of established building companies. So, no matter where you are at, we can definitely help you.

Additionally, you may have questions about the ideal building site, the best orientation or what it costs to build a new undercroft home. Or perhaps you need assistance with block selection, advice on swimming pools or are not sure how to choose a builder best suited to your particular build. We can assist you with all your questions and help you make an more informed decision about undercroft home designs.

While it’s impossible to answer all your questions here, we’ve prepared some answers to some common questions. If your questions aren’t in the list below, then please feel free contact us to discuss your particular situation. We’re here to help you and there’s no such thing as a stupid question, so fire away.

Based on our website and the undercroft home designs featured, many people think we are expensive home designers or only design million dollar undercroft homes. Neither are actually true. We design undercroft homes with budgets from $450k through to millions in value. No matter what your budget, you’ll experience the same passion & dedication because every home designed is done so by Boyd himself.

Similar services can cost 10%, or more, of the total project value. This fee is often applied to everything. The house, earthworks, the landscape & finishing items. We believe this, being paid a percentage for items not even designed, is ridiculous. We charge only 4.5% of the budget for the house itself. This means our fee isn’t applied to earthworks, finishing items, the landscape or anything else.

For example, let’s say you have a total budget of $500k (excluding land) to build your home. We’ll deduct the estimated costs of earthworks, floor coverings, air-con, the landscape and so on. If the total cost of these items is estimated at $120, this leaves a budget balance of $380k for the house itself. Our fee is only applied to the $380k. 4.5% of $380k is $17,100.00 plus GST.

Considering our written guarantees & complimentary landscape design, we truly believe we are the best value undercroft home designers around.

With some architects & home designers, yes. Not so with Boyd Design.

Boyd has designed undercroft homes for people who have known what they don’t like, not what they actually do like. He has also designed homes for people who’ve had no idea what they like. One which stands out is a client who handed Boyd plans of a home based totally on hexagonal shapes. From the entry foyer to the rooms, everything was a hexagon. The resulting home design was so far removed from these plans, not one thing remained the same. In fact, the home is featured on this website. Take a look here.

Boyd is certainly no “yes man”. He’ll listen to your ideas and develop these into a undercroft home plan which is perfect for you in every respect. He achieves this through his unique interview process. By the time he’s done, he’ll know exactly who you are, how you function as a family and anticipates your needs in ten years’ time. This is why we can guarantee the results in writing.

As you can see on this website, there is only one undercroft home design style Boyd know’s how to design, yours.

No matter what style of undercroft home you seek, Boyd will create it for you. In fact, he has created home styles which are so unique they can’t actually be categorised.

As a genuinely passionate home designer, Boyd works tirelessly to ensure you’ll absolutely love every aspect of your new home design. He is also the only home designer, within Australia, who guarantees this is writing.

No, we are home designers – not builders.

We are able to assist you in obtaining cost estimates from builders and can suggest a few builders to you. You are also free to choose any builder you like because, unlike many home designers & architects, we don’t take referral fees from builders. This means we’ll suggest builders we trust to deliver quality & value, not just those lining our pockets.

With more than 30 years experience with the building industry, Boyd will know the estimated cost of building your undercroft home before you engage our design services.

Before we take you on as a client, you’ll meet with Boyd to discuss your new home in detail. Taking around three hours, this meeting is much more than a “get to know you” type of meeting, Boyd will ask you many questions to gain a sound understanding of the undercroft home you want and compare this with the allocated budget.

In some cases, Boyd may say “Sorry, your expectations are unrealistic”. In others he’ll say “Your budget is realistic but may be a little short”. In some very rare cases, the expectations of the client are actually aligned to their budget. The fact is, we all want more than we can comfortably afford. No matter if the budget is $450k or $2.5m, it’s a rare event that a client can achieve all their heart desires.

So, even before you have committed to Boyd Design, we establish the estimated cost to build your home. Doing this in advance is important to us and to you. As responsible home designers, we don’t want to take your money if your expectations are unrealistic, there’s no point in doing so.

There is no standard answer to this as every undercroft home is different and presents a unique set of design challenges. The duration of the process is also largely dictated by the client. Some respond quickly with feedback on their design, while others may take weeks.

Subject to a number of things, the process usually looks like this once the documents are signed and the deposit paid.

Initial Design Plans: Up to six weeks (usually delivered within this time).

Desired Design Changes: One week (there can be several rounds of desired changes).

Working or Detailed Drawings: Four weeks (usually delivered within this time).

The thing about home design awards is that you must actually enter them to win.

Boyd is a firm believer that, while design awards could be a great marketing tool, they don’t actually mean very much. Boyd truly believes that the only people qualified to judge his home designs are the people who actually live with the split level homes he designs. After all, it’s not about how trendy or clever the home design is, it’s about how it responds to the needs of the family living with it.

You can read some testimonials on Houzz here, or you can request the contact details of past & present clients. And we promise you none of these clients are Boyd’s family or friends.

The payment of our design fee is spread out over a period. There is an initial deposit which is then followed by four progress payments as follows.

Initial Deposit: 30%

Upon Completion of the Initial Floor Plans & Elevations: 20%

Upon Completion of any Desired Design Changes: 25%

Upon Completion of the Working Drawings & Final Landscape Design: 25%

There are additional costs associated in order for your home plans to progress to a stage where you can actually build your home. These include, but are not limited to, the following.

Energy Efficiency Report, Engineering Details, Land Surveyor, Building Assessor, BAL Assessor & Council Application Fees. The cost of these items are not included in the fee charged by Boyd Design. However, based on your proposed home and your site, Boyd can estimate these costs for you in advance.

Yes we do!

No matter where you are building, we can design your undercroft home. Within Australia or overseas, there is nothing stopping you from engaging the services of Boyd Design.

We have designed homes in NSW & Queensland and worked with clients based in China, location makes no difference.

Indeed we can!

We have developed a building system which can save you around 20% while your home is built in around half the time of regular brick homes. In addition, these homes include double-glazing, lacquered cabinets, stone tops and have far superior thermal & acoustic values.

Designed to look no different to rendered, double-brick homes, these homes are built using a combination of steel & concrete.

In our opinion, these homes are of far superior quality and offer so many more genuine benefits over traditional brick homes.

Call Boyd to discuss these homes in greater detail.

The very first thing to do is call or email Boyd to describe your home in general. During this conversation, he will ask you some questions about your proposed home, your site and your budget.

If all looks achievable and you wish to take the next step, you’ll then book a free design consultation with Boyd. Held at our office and taking around three hours, you’ll chat about your home, your family, your ten year plan and your lifestyle in greater detail.

Within the next few days, you’ll receive our quotation via email. This email will include a letter of engagement (describing your home in words), a schedule of works (details describing what is and what isn’t included in our design fee) and a home design contract.

Should you wish to proceed, you’ll return the completed documents via email and we’ll then invoice you for your deposit.
