Residential Landscape Design

J Duggan & Associates has a passion for residential and estate design.

We have performed design/build services, and managed the installation of hundreds of residential projects in the Metro DC region–particularly in Loudoun, Frederick, Fauquier, and Warren Counties of Virginia.

We stay small, human and flexible, so that our principal, J. Duggan, stays personally involved with your residential landscape design project.

Our Residential Landscape Architecture Experience

Our projects have ranged from simple entryways for a few thousand dollars, to the master planning and installation of major estates with project costs well in excess of six figures.

Our experience includes plantings, lighting, decks, terraces, patios, pools, water features, walls, and grading using a number of different methods including carpentry, masonry, etc.

We know what does and doesn’t work. We are able to offer residential landscape architecture that not only enhances your home and lifestyle, but fits your budget too.

We providing design solutions for your property that maximize its potential according to its unique characteristics, and your needs.

Why pay for a design/consultation when I can get one ‘free’ or cheaper from a design/build firm?

Many contractors ‘bundle’ a design consultation as part of your construction package, or offer it for free. But remember; nothing is free.

No matter how qualified they may be, if you are not paying for the design, then your ‘design’ is used to sell their construction service.

No ill will is intended, but their goals’ may not be the same as yours. If they find patios or decks profitable this time of year, they will encourage you to get them.

You also have to consider who is actually doing the design. 

What are their qualifications and experience? Many assume the designer must be qualified if the company has been around for a while. Not necessarily. Investigate the designer who will be advising you!

They may not charge you up front for design  services, but they will include the fees in the final construction costs. Office overhead and marketing costs etc all have to be covered. You may not see the cost as a line item, but it’s there!

Naturally, “designer/salesmen” have to be paid for their time. Any reputable firm has to cover all items relating to a project.

You just don’t see it immediately. You will pay for it later.

Skip the drama.

Hire a professional, experienced architect ready to explore your vision, detail your dream, and enhance your landscape with excellence and precision.

Enjoy a leaner budget, and give the contractors exactly what they need; custom designs that eliminate the guesswork, plan for the future, and maximise your property’s potential.

What Sets Our Residential Landscape Design Firm Apart?

1. We value honesty.

No matter the size of your project, we know you need to trust your landscape architect. We create every design with you from scratch – without any hidden fees.

2. We listen to you.

Nothing is more frustrating than designers who won’t pay attention to you. No one knows your needs or has more experience with the property than you. Our process ensures that you are included in all stages of design.

3. Our network.

After more than thirty years of projects, we’ve had ample time to learn which professionals are really professional. After we implement a design process that puts you first, we can then use our network to build the best team to implement the solution.


We very much appreciate the design you have created for us. The landscape/pool design was very intriguing, and we love the way you designed the driveway and the front entrance walk. They add a lot of interest to the house and general design. Looks like we will soon be breaking ground, and it is great to have this concept plan to work with.

I have worked with Joe on projects large and small since 1988. As a professional horticulturalist and nurseryman, I appreciate Joe's knowledge of plant material and appropriate application of trees and shrubs in a landscape. He not only draws a pretty picture, but creates functional, maintainable outdoor spaces that add value to homes and business. I do not hesitate in recommending Joe for any project.

I was considering improvements for my residence in Frederick County which included a pool with hot tub and its surrounds featuring an outdoor fireplace. The site itself is unique- so I was concerned with whom to work with regarding this, I was especially concerned that the design not intrude on a view I have of a lake bordering my property. In short I wanted the pool and surrounds to complement the overall aesthetics of my property, not compete with it. I was also concerned with finding the proper contractors to help with the installation of the project once the design was complete. I decided that a ‘Master’ Plan needed to be prepared in order to cover all the options and just as important establish and work with a budget I was comfortable with.

Joe took the time to get to know the site and understand how I wanted to use it. Joe’s style is very collaborative-keeping the client involved. Once he completed initial sketches of options for the space he met with both myself and my children to discuss the options and listened closely to our feedback. Once an option was selected (with modifications based on feedback) Joe kept us in the loop by sending updates of the design via graphics sent by email and follow up meetings. The end result was a design that we were satisfied with.

Once all the details were set Joe then arranged for items to be bid through his list of contractors and craftsmen, We met with numerous contractors, requested and reviewed the bids, revising the design as needed, and sending them out again for revised estimates. Once the team was selected, Joe helped with contract negotiations, making it a point to be available to answer questions as they came up. I particularly appreciate his knowledge of the trades and his willingness to listen and revise the design per contractor’s feedback- in short he has a real respect for the folks who do the actual work-making this a collaborative effort.

The project has been completed I am pleased to say things went well , and I look forward to enjoying my new space for years to come. I would recommend Joe to anyone considering a project of this type themselves, they will be in good hands.
