There are many reasons why engaging our services is considered to be the smart choice by our clients. Everybody has his or her own priorities.

Trustworthiness and experience is at the core of our business. We know that our happy clients are our biggest assets. We will go the extra mile and take care of you.

We want your building process to be smooth and enjoyable so you can sleep well at night.

What matters to us most during a design project are the PEOPLE, – who they are and how they live their lives. In fact, energy does not even come up much when we work with our clients. You tell us your priorities and we help you realize your dreams and take care of the rest.


Don’t take it from us but take it from our clientele:

I have been working with Joaquin on two occasions, first on my new home in Taos and then on my new outdoors shade structure. The process of designing and creating with him has been an inspiring and exhilarating experience for me. With his professional training in his native Germany he is far ahead of the curve in efficiency and design.


Joaquin has the unique ability to listen to his clients. I loved the open exploration and communication. He incorporated my visions and needs into an esthetically and functionally pleasing whole. One that is also harmonious with its natural surroundings.


The love and enthusiasm for his work and each new project, large or small, are palpable.

When I began my search for an architect I didn’t know what I wanted. After speaking with Joaquin it became clear I wanted to build a home as energy efficient and as attractive as possible. Not only did he have the knowledge and experience that could make this a reality but he also found a way to incorporate my interest in Vastu principles and create a beautiful Bramastan, which lets me enjoy a great sense of harmony and balance.


Many architects and builders talk about being “green”, Joaquin puts his words into action. Today, my home is incredibly efficient and beautiful. Thank you Joaquin!!!

We cannot recommend Joaquin Karcher and Zero E Design highly enough. The home we build with Joaquin’s help won an award as one of the two most energy efficient homes built in New Mexico in 2009, and it’s featured in a book entitled Toward a Zero Energy Home.


But more important, we absolutely love our Taos area home and its incredible ease of use and efficiency.


Joaquin really listens to his clients and works with you to achieve your personal vision as he instructs you in the details of green and energy-efficient design.


Joaquin’s aesthetics are superb as well. We loved the process of working with him and his continued help was excellent through the actual construction. Joaquin gets our unqualified endorsement.

I’d never worked with a design professional before and the process was fascinating and educational. Joaquin would create what was possible from my ideas and dreams, teaching me a lot along the way. What he created defies explanation — everyone who comes in gasps — and many of these people have seen myriad photos before arriving. For a space under 1,000 sq ft it feels almost palatial and truly soars.


The passive solar aspects have been heating the house beautifully and I’ve hardly used the active solar heat. I wanted a house I could actively participate in and that is working perfectly. I have a greenhouse integrated to the house, as well as a woodstove to supplement the hot water when we have cloudy weather. All these systems are working flawlessly and allowing me the hands on experience I want. I’ve never lived in a house where I could be so warm and comfortable in severe cold. No draft, always even temperatures and always fresh air… the only drawback is that I could never live in a regular home again.
