Renovating in Forest Hills?
Before we talk about your home, we want to talk about your life.
We Know Forest Hills
Forest Hills is Washington's most architecturally eclectic neighborhood, and the name tells you why. Bounded by Connecticut Avenue to the west, Rock Creek Park to the east, Van Ness Street to the south, and Broad Branch Road to the north, this is a neighborhood of wooded hills, winding roads, and homes that range from stately 1920s colonials to bold mid-century moderns to striking contemporary custom builds. Unlike the streetcar suburbs to its south, Forest Hills was not developed by a single company on a master plan. The hilly, wooded terrain discouraged early large-scale development, leaving substantial parcels available well into the mid-20th century for individual buyers who commissioned custom homes from prominent architects.
The result is a neighborhood where a brick Tudor sits next to a cantilevered contemporary overlooking Rock Creek Park, where a Colonial Revival shares a street with a flat-roofed mid-century modern designed by Charles Goodman or Chloethiel Woodard Smith. More than fifty mid-century houses were built here in the late 1950s and 60s, tucked into hillsides and wooded sites. Embassy residences and ambassadorial homes occupy some of the largest properties. Connecticut Avenue provides access to restaurants, shops, Politics and Prose, and the Van Ness Metro station. Murch Elementary, Deal Middle, and Jackson-Reed High serve the area, and Rock Creek Park is not just nearby but woven into the fabric of the neighborhood itself.
You live in Forest Hills because you found something that barely exists inside a major American city: a wooded, private, architecturally adventurous neighborhood where the houses are as individual as the people who live in them. The house just needs to match the life you are living in it.
The Right Questions Come First
Most renovation firms will ask you what you want to do to your house. That is the wrong first question.
We start with why. Why are you thinking about this now? What changed? What is not working? What does your day actually look like in this home, from the moment you wake up to the moment you go to bed? Where do you feel friction, and where do you feel at ease?
This is not a soft, feel-good exercise. It is the most practical thing we do. Because if we do not understand why you want to change your home, we will end up designing a beautiful space that solves the wrong problem. And that is an expensive mistake.
We call this approach “Why before What,” and it is the foundation of everything we do at Designed Happy. We have built an entire framework around it called DesignCOMPASS, a suite of three tools (the Five Whys, Heat Maps, and the Future Test) that helps us uncover what your home actually needs to do for you, not just what it needs to look like.
It is the difference between a contractor who says “we will open up the kitchen” and an architect who says “let me understand how your family uses this house before we touch a single wall.”
What Forest Hills Homeowners Are Thinking About
After 20+ years of working on residential projects in the Washington, D.C. area, we see patterns. Here is what Forest Hills homeowners tend to be wrestling with:
The Mid-Century Modern That Deserves a Modern Update
Forest Hills has one of the largest concentrations of mid-century modern homes in Washington, D.C. Flat roofs, walls of glass, open floor plans, natural materials, and a relationship to the wooded landscape that was ahead of its time. These homes deserve an update that respects the architectural intent: contemporary kitchens and baths, new mechanical systems, better insulation, updated windows, and modern materials, all without losing the design vocabulary that makes them special. Renovating a mid-century modern well requires a designer who understands the style, not just the square footage.
The Colonial or Tudor That Needs a Real Update
Forest Hills' traditional homes, built from the 1920s through the 1950s, share the same fundamental needs as their counterparts throughout upper Northwest: small closed kitchens, original bathrooms, undersized electrical systems, and mechanical systems past their useful life. But Forest Hills lots are often larger and more heavily wooded than other D.C. neighborhoods, and the homes themselves are frequently more generously scaled. Modernizing a 3,000 to 5,000-square-foot colonial or Tudor requires a team that can manage the scope while respecting the architecture.
The Whole-Home Renovation
When the project touches every level, every room, and every system, it needs a team that can see the whole picture. Architecture, interior design, and construction working together from day one. In Forest Hills, that means understanding D.C.'s zoning regulations, the environmental sensitivities of wooded hillside lots, the construction logistics of working on steep grades with limited staging area, and the specific structural realities of the home you are renovating, whether it is a 1920s masonry colonial or a 1960s post-and-beam contemporary. These are complicated projects. That is what we specialize in.
Additions on Wooded Hillside Lots
Forest Hills lots are often generous by D.C. standards but challenging to build on. Steep grades, mature trees, rock outcroppings, and proximity to Rock Creek Park create constraints that flat suburban lots do not. Adding a primary suite, expanding the kitchen, or creating a family room addition requires working within D.C.'s zoning envelope while navigating the site conditions that make Forest Hills unique. We design additions that work with the terrain rather than fighting it.
New Custom Construction on Significant Sites
Forest Hills has an active custom construction market, with new homes designed by prominent architects appearing on prime lots. Whether building new on a cleared site or replacing a home that has reached the end of its useful life, the opportunity to create something exceptional on a wooded D.C. lot overlooking Rock Creek Park is rare and significant. We bring architecture, interior design, and construction together from the earliest concept to deliver homes that belong on their sites and in their neighborhood.
What Makes Renovating in Forest Hills Different
Forest Hills is not a designated D.C. historic district. That means most renovations do not require Historic Preservation Office review, which simplifies the exterior approval process compared to neighboring Cleveland Park. But D.C.'s own regulatory environment is substantial, and Forest Hills' wooded hillside lots add site-specific complexity that most D.C. neighborhoods do not present.
The D.C. Department of Buildings handles all building permits. Permit applications for residential work begin through the D.C. Permit Wizard and require signed plans from a registered architect, stamped structural engineering drawings, and MEP engineering. Civil engineering may also be required for site and utility permits, particularly on Forest Hills' sloped lots where grading and drainage are significant considerations. We submit complete, code-compliant packages that move through D.C.'s multi-agency review efficiently.
Some properties may be individually landmarked or fall under Shipstead-Luce. While Forest Hills is not a historic district, individual properties may carry landmark designations, and properties abutting Rock Creek Park fall under the Shipstead-Luce Act, which places them under the design review authority of the U.S. Commission of Fine Arts. Given Forest Hills' extensive frontage on Rock Creek Park, many properties are subject to this additional federal review layer. We verify your property's status before design begins.
D.C. zoning governs what you can build. Forest Hills includes R-1-A and R-1-B zoning (low-density residential). The zoning code controls lot coverage, building height, setbacks, rear yard requirements, and floor area ratio. On Forest Hills' irregular, sloped lots, the relationship between the zoning envelope and the actual buildable area requires careful site analysis. Grade changes affect how building height is measured, which can significantly impact what is possible. We design within the zoning envelope from the start.
Tree protection is enforced, and Forest Hills has more trees than most. Washington's Urban Forest Preservation Act protects Special Trees (100-inch circumference or more). Forest Hills' dense canopy means these regulations affect nearly every project involving exterior work, grading, or construction staging. Mature trees on steep slopes also play a role in soil stability and drainage. We assess tree impacts and site conditions together before design begins.
Hillside construction logistics require advance planning. Forest Hills' steep grades, narrow winding roads, and limited staging areas mean that construction logistics, from equipment access to material delivery to dumpster placement, require planning as part of the design process. On hillside lots, grading, retaining walls, and drainage engineering are not afterthoughts. They are integral to the project design. We plan site logistics and construction access from the start, not as an afterthought once permits are in hand.
None of this should scare you. It just means you need a team that knows how this works before you start, not one that figures it out as they go.
