Vancouver Luxury New Custom Home

Building Site


It's important to verify that your selected home building lot is suitable to build what you want. 


This applies whether you're building on your existing lot or buying a new home building lot.   


We review your site to confirm your proposed development is feasible and identify red flags that may negatively impact your home design. 


This is one of the crucial first steps to starting any Calgary home design and building project.

Building Design

This is where our creativity shines!  A GREAT custom home design is the difference between a finished custom home build that you LOVE ♥... or one full of "design regrets".  You only get one chance to design your custom home properly, so make sure you get it right by working with a highly experienced home design team! 

Our custom home designs have  been recognized across North America, and have been nominated and won over 23 awards.

The various Building Codes and Zoning Bylaws which govern Calgary home designs require certain documents be submitted along with architectural drawings and for the purposes of your Permit submission.

These documents are obtained from  "third party consultants".  The list is different for each Calgary-area municipality.  However, some examples include a Structural Engineer, joist and truss design,  Energy Consultant, and the list goes on... 

We'll be straight up with you...This part of the process is usually extremely technical and boring for homeowners. 


But it is 100% mandatory.

This is why we will take care of this entire process for you.

Custom Home Budget Management

Your new custom home budget needs to be managed responsibly throughout all stages of the project.

Our team will be involved in helping you establishing your initial budget range, and working together with the custom home builder throughout all the various stages of the process to make sure your budget is respected.

Regardless of how large or small your home building budget is, our team will always treat your money like our own, and find innovative solutions to get the most bang for your buck, and balance this with preserving quality.

Project Management

Before starting any custom home design, there's a lot that happens behind the scenes.


We help you map out and plan your entire project from these early stages to construction. 


We discuss budgets, the process, and ensure your custom home building project is planned out for success. 

Sound overwhelming? 


Don't worry, we're your Trusted Advisors through the whole process.  We'll keep things detailed, but simple.  We know you're busy and have a ton of other things to do.  We're here for you. 

Vancouver Interior Design


Interior Design

Your home's architectural design is only half of the equation.  As the architectural design is in progress, it's important to consider the interior design, and integrating this with the overall home design.

It can be overwhelming with all the choices, but our streamlined design process makes it easy and fun.

Our interior design team specializes in residential design, and has 10+ years experience creating beautiful and functional interiors.  We will help you with everything interior design related.  This includes mill work design, lighting design, interior finishing selection, window coverings, furniture, and decor. 

Your new custom home will  will be beautiful and fully move-in ready once we're done.

If you have a third-party interior design firm that you'd like to work with, we are also happy to collaborate with them too!

Permit and Approvals Management

All Calgary home designs require approval from a Governing Authority, and in some cases, more than one. 


You may have heard horror stories of home design projects being stuck in permits for an extended period of time.


The reality is... if you have an experienced design team managing and negotiating your permit, this can save significant time (in some cases months) during Approvals.


We have completed hundreds of Calgary home design approvals - both simple and complex.  We understand the requirements, process,  strategies for each community, making this stage of your home design stress-free and as quick as possible.

Seeing your custom home design come to life is one of the most exciting parts of the process!

But it can also be a bit intimidating, as there is a lot going on.

We are here to support you during this phase.  At this point, your Calgary custom home builder should be managing the project on a day-to-day basis.

However, it's always great for our home designers and the custom home builder to collaborate during construction, especially if unexpected items come up.  We are here for you through the entire construction.

Vancouver Home Design Due Diligence


Due Diligence

As we start design, there is additional due diligence required.  For example, all Calgary home designs are subject to  Land Use Bylaw and Alberta Building Code restrictions. 

At this stage, your home design project is prepared to enter the conceptualization stage.  This includes requesting information from consultants, reviewing Title documents, ensuring  Architectural Design guidelines are followed and a lot more.

We will take care of all of this for you.


It's of utmost importance your design team is familiar specifically with Calgary custom home design, (like ours), and is highly experienced in navigating these regulations, and without compromising the beauty and function of your home design.

3D Visualization and Renderings

We get it.  Floor plans can be hard to read.


You want to make sure you're making all the right decisions throughout your home design process.  But first, you need to understand what exactly you're looking at.  That's where 3D visualization comes in. 


We have powerful tools we utilize throughout the entire design process.  Your design presentations are all completed in a 3D environment, among many other visualization tools and techniques we have.


It's our job to deliver a beautiful home design.  But it's also our job to make sure you understand exactly what you're getting, before you commit to starting construction. 

In this way, you can make educated and confident decisions.


We do all of that within our design process.

Ask us how.  Reach out to get more information.

Custom Home Builder Selection

Every custom home design will inevitably require a custom home builder (of course!)

Finding and selecting a home builder can be incredibly intimidating.  That's why we'll lead you through this process too.  We've worked with numerous Calgary custom home builders, in Calgary and all across the province of Alberta.  With our local experience, we know "who's who" when it comes to custom home builders.  We know who's good (and who's not so good). 


If you've already selected a home builder, or have your own shortlist in mind, we are always happy to work with them too!

Regardless of whether it's a builder we recommend, or a builder that you've brought to the table, we help you through the entire selection process with our unbiased opinion, and so you're confident in your final home builder selection.


The Calgary home design process is much more than just design.  There is a LOT involved to execute a custom home design and build project properly. 


It can be overwhelming and confusing.

That's why we offer a turnkey concierge-style service, tailored to busy professionals.  We navigate you through the entire process.  We take care of all the details.  From start to finish.  A summary of what our service includes is below.

We work side-by-side with you to capture your vision, but lead you through the process to make it the best it can be. 

We believe you should get the design YOU want. 

Not what we think you should have.  Or what might win an award (...unless of course, you tell us that's what you want - we can do that too 😉)

But unlike some other firms, we will never force our ideas upon you.  In the end, it is your home.  Customized exactly to suit you.
