Office Barn Renovation

Follow along as we renovate a 1905 barn and make it our home office! This building was originally located off Dollar Street in West Linn, Oregon, and was torn down, moved, and rebuilt on an Old Willamette property in the 1980s. It is still designated as a Historic property today.

Our Sustainable Practices

Sustainability and long-term landscape performance are integrated throughout our planning and design process. Our work emphasizes adaptive site design, efficient resource use, green infrastructure, and context-sensitive landscape strategies that support ecological function, regulatory compliance, and long-term maintainability.

Our landscape designs incorporate the following sustainable practices:

Municipal Climate and Resiliency Alignment: Designs are developed in alignment with applicable municipal plans and policies, including urban forestry plans, climate action plans, transportation master plans, and watershed management objectives, supporting long-term community resilience goals.

Stormwater Management: We incorporate Low Impact Development (LID) strategies consistent with applicable municipal codes and regional stormwater manuals, including Clean Water Services standards and the Stormwater Management Manual for Western Washington (SWMMWW). Planting plans are coordinated with stormwater requirements and clearly document applicable planting metrics and performance criteria to support efficient permitting processes and long-term site sustainability goals.

Soil Preservation and Restoration: Soil preservation and restoration approaches are integrated throughout site planning, design, and construction to support long-term landscape performance and stormwater function. Soil tests inform planting design, overall site layout (including stormwater features), irrigation design, and soil amendment recommendations, based on an evaluation of pH, soil composition, percolation rates, and seasonal water table conditions. Where feasible, native soils are preserved by minimizing disturbance, limiting unnecessary grading and tilling, and protecting soils from compaction during construction. Construction specifications promote proper soil stockpiling and erosion control measures during and after construction to support successful landscape establishment.

Support Alternative Transportation Modes: Site and streetscape designs support multimodal transportation networks through coordinated pedestrian environments, streetscape plantings, bicycle-supportive infrastructure, and accessible circulation systems, integrated with transit connections and pedestrian activity patterns, to encourage reduced vehicle dependency.

Climate-Adaptive Planting Design Strategies: Our planting palettes incorporate native and climate-adaptive species responsive to Pacific Northwest microclimates and site conditions, reducing irrigation demand, supporting habitat and biodiversity, and minimizing long-term maintenance requirements. 

Reduced Turf Strategies: During design development, we carefully evaluate the site’s programming requirements for traditional lawns to determine the smallest possible lawn footprint, reducing long-term resource inputs while still meeting programmatic needs. In all other areas, we prioritize climate-adaptive planting, no-mow grass areas, meadow plantings, and other low-water landscape alternatives where appropriate.

Irrigation Plans: Our planting and irrigation plans are coordinated through strategic hydrozoning to support efficient water use. Irrigation systems incorporate smart controllers, sensors, and high-efficiency components to reduce water demand, improve distribution uniformity, and minimize runoff and overspray.  

Microclimate and Tree Canopy Strategies: Tree placement and canopy strategies are developed in response to site microclimates, circulation patterns, and adjacent building conditions to support thermal comfort, passive energy conservation, and long-term climate resilience. Where appropriate, deciduous canopy trees are positioned to provide seasonal shading, while evergreen planting may be used to support wind buffering and year-round screening.

Material Specifications: Our designs consider carbon footprint and material efficiency in product specifications. Impervious hardscape areas are minimized where feasible to reduce runoff, support stormwater infiltration, and limit heat gain within the landscape. Projects prioritize permeable paving options. Site layouts and material dimensions are coordinated to improve material efficiency and reduce construction waste associated with excess cuts and unused materials. We also prioritize the use of local and reclaimed construction materials where appropriate, reducing transportation impacts while supporting regional suppliers and long-term site sustainability.

Reuse of Existing Site Materials: During initial site analysis, we evaluate existing materials, vegetation, and site features to identify opportunities for retention, salvage, and on-site reuse, thereby reducing waste while supporting durable, context-sensitive design solutions. 

Landscape Lighting: Our low-voltage lighting plans support DarkSky principles through careful fixture selection, directional lighting strategies, and appropriate color temperature specifications to reduce light pollution and unnecessary energy use. Lighting layouts prioritize safety, functionality, and long-term maintenance efficiency while minimizing impacts to adjacent properties and wildlife. Where appropriate, lighting systems may incorporate motion sensors and replaceable lamp components to reduce energy consumption and support long-term material sustainability.

Fire-Resilient Design: Project sites are evaluated for wildfire risk and applicable municipal or Wildland-Urban Interface (WUI) requirements during early site analysis. Where appropriate, fire-resilient design strategies may include defensible space planning, fire-resistant plant selection, strategic plant spacing, reduced fuel loads near structures, and site layouts that support emergency access and long-term landscape resilience.

Long-Term Landscape Performance: Landscape systems are designed with consideration for long-term maintenance, durability, and lifecycle performance. Planting strategies, material selections, and site layouts prioritize resilient landscapes that can be maintained efficiently while supporting long-term ecological and functional goals.

Existing Tree Preservation: Existing mature trees and vegetation are evaluated early in design to identify preservation opportunities that support long-term canopy health, reduce heat gain, preserve habitat value, and maintain neighborhood character. Design strategies consider critical root zone protection, grading impacts, and long-term site viability during construction and implementation.

Ecological Restoration and Invasive Species Management: Where applicable, landscape strategies incorporate ecologist recommendations, invasive species management approaches, and restoration-oriented planting design to support rehabilitation of disturbed landscapes and long-term ecological function.

FAQ

1. What is the difference between a Landscape Architect and a Landscape Designer?

A Landscape Architect will have greater technical knowledge and experience in plant and structural design, while a Landscape Designer will focus more on aesthetics, plant selection and layout design. A Landscape Architect requires more education and licensing. They often undergo intense training in design principles, site planning, ecology, horticulture, and construction. 

The scope of work for landscape architects and designers varies as well. Landscape architects are licensed professionals who can engage in a broad range of projects including large-scale planning, urban design, public spaces, parks, city planning, and other work that involves complex engineering and environmental concerns. Landscape designers often focus on smaller-scale projects such as residential gardens, outdoor living spaces and smaller construction projects. 

2. What can I expect throughout your design process?

Our project approach involves meeting with our clients and having a detailed conversation regarding scope of work, schedules, client expectations/deliverables and ongoing progress updates of the varying design phases such as (1) Schematic Design (2) Design Development (3) Construction Documentation and (4) Construction Administration and Observation. Please visit our Services Page to learn more.

3. Can you supply all sub-contractors after the design is complete?

We have a thorough list of trusted contractors that we can provide to you after our design. We always recommend getting multiple bids to ensure you are getting a fair price and are happy with their proposal.

4. On average, how long does it take to have plans designed for my home?

Timing depends entirely on scope of work, but on average it takes a couple months to deliver plans to our clients.

5. I want my yard to be eco-friendly/green landscape. Is this something you can provide?

Yes, we are an environmentally conscious landscape architectural firm that routinely integrates sustainable practices into our designs. We promote sustainable development, green infrastructure, sustainable urban development, the application of ecological design, the improvement of water management, the increase of energy efficiency and the use of low impact materials.
