HKP Ar­chi­tects has been pro­vid­ing ar­chi­tec­tural ser­vices to the Pa­cific North­west since 1952. Founded on the values of honesty, simplicity, and service, our firm is highly respectful of our many long-term relationships with clients and the community. Our work shows re­mark­able con­sis­tency over the past six decades, and we remain dedicated to providing architectural design that is high-value, environmentally responsible, and sensitive to its site.

We focus on civic build­ings and spaces, ed­u­ca­tional fa­cil­ity plan­ning and de­sign, non-profit and com­mu­nity-ori­ented pro­jects, and pri­vate homes; work that lifts peo­ple up in their lives. Whether they are places of learn­ing, af­ford­able hous­ing or cul­tural in­sti­tu­tion work, our ob­jec­tive is to re­al­ize our clients’ vi­sion and op­ti­mize every op­por­tu­nity. 

All of our projects emphasize long-term value for our clients through efficient use of space, appropriate use of materials, sustainability, and the benefits of natural light.

HKP Ar­chi­tects is a Women Business Enterprise (WBE)-cer­ti­fied firm.

Founded as Henry Klein and As­so­ci­ates in 1952, HKP was the first full-ser­vice ar­chi­tec­tural firm in Sk­agit County, Washington. Founding principal, Henry Klein, a na­tive of Eu­rope, was one of the Pacific Northwest’s most lauded architects. His legacy includes designing many of the region’s iconic mid-century modern homes and civic buildings.

Klein’s colleagues recognized his influence on Northwest architecture in conferring the AIA Seattle Medal to him in 1995. In his acceptance speech, Klein noted:

“…the simple notion of architecture as the spaces we separate from the infinite space surrounding us and then enclose: spaces that still retain all the various and changing light, colors, textures, sounds and mysteries of the universe. But because architecture is of human scale and dimensions, we can bring these wonders home and make them felt by ordinary people of all ages, backgrounds and stations in life.”

This reverence for the power of architecture, and its effect on people of all ages and cultures, remains a vital part of HKP’s mission to this day. Current HKP partners Julie Blazek and Brian Poppe carry forward the firm’s legacy to elevate the human spirit through use of space, materials, light, and sustainable design.

“In my deal­ings with HKP staff, I have found them to be highly com­pe­tent and pro­fes­sional, skilled in dis­till­ing the needs of the Tribe and in trans­lat­ing those needs into use­ful and ser­vice­able fa­cil­i­ties. They main­tain a high level of qual­ity and re­spon­sive­ness in their work and great at­ten­tion to de­tail, which has re­sulted in nu­mer­ous prod­ucts of great value to the Tribe. I would give my high rec­om­men­da­tion for them to any­one seek­ing skilled and highly qual­i­fied ar­chi­tec­tural ser­vices.”

Sus­tain­able de­sign prin­ci­ples have al­ways been at the heart of our de­sign
de­ci­sions, par­tic­u­larly when it comes to Passive House technology, nat­ural ven­ti­la­tion, pas­sive so­lar strate­gies, light, views and ma­te­r­ial ex­pres­sion in the Pa­cific North­west. HKP Ar­chi­tects ac­tively in­cor­po­rates sus­tain­able de­sign prin­ci­ples in all of our work and we at­tempt to help clients un­der­stand the long-term ben­e­fits both to our en­vi­ron­ment and to their op­er­a­tion and main­te­nance costs. Partner Julie Blazek is a Certified
Passive House Consultant and two of our staff are LEED Accredited Professionals.

HKP launched an internal Sustainability Policies & Initiatives program in 2020. The vision of the program is to review our business operations and building maintenance through the following Triple Bottom Line lens:

  • Environmental Impact
  • Social Impact
  • Financial Impact

The program outlines a range of efforts towards reduction, recycling, and reuse of materials, buying from local sources, sourcing from sustainable and ethical companies, reducing our carbon footprint and improving our building’s efficiency. It relies on leadership at all levels and depends on our staff to be as dedicated to these principles as the firm partners. It is intended to hold us all accountable for the impacts of our decisions, both positive and negative, towards the environment and society. We, as individuals and as a whole, can lead by example with our clients, peers, and community.

We be­lieve it takes more than great build­ings to build a strong com­mu­nity: com­mu­nity out­reach and in­volve­ment is also a pri­or­ity. We en­cour­age our team to serve and con­tribute in var­i­ous ways. Lo­cal or­ga­ni­za­tions sup­ported by HKP col­lec­tively or in­di­vid­u­ally by our em­ploy­ees in­clude:

“HKP Ar­chi­tects have now taken two blank slates and trans­formed them into mag­i­cal spaces at the Chil­dren’s Mu­seum of Sk­agit County lo­ca­tions. Their vi­sion for de­sign and com­po­nents led us to cre­ate and en­hance the ex­hibit de­signs into vi­brant spaces, uti­liz­ing the avail­able square footage to op­ti­mal use and value. They also pro­vided ex­cel­lent at­ten­tion and guid­ance through­out the plan­ning and build-out phases at both lo­ca­tions.”
