Modern Additions & Transformations
More space. Better flow. A home that finally works for you.
A modern addition isn’t just about adding square footage — it’s about rethinking how your home functions. Most families come to us because their home feels tight, dark, or disconnected. An addition paired with a thoughtful reconfiguration can completely transform the way you live.
We help homeowners in the DC metro area create modern, intentional spaces that feel calm, open, and built for real life.
Why Additions and Reconfigurations Go Together
Most additions aren’t standalone projects. When you add space, you almost always need to:
open up circulation
improve natural light
reconfigure the kitchen
update structural systems
modernize outdated layouts
create a better connection to the backyard
This is why we approach additions as whole‑home transformations, not isolated boxes tacked onto the side of a house.
The goal is a home that feels cohesive — old and new working together seamlessly.
What a Modern Addition Should Feel Like
A modern addition isn’t about making your home bigger. It’s about making it better.
We focus on:
clean, simple forms
warm, durable materials
natural light and openness
functional flow between spaces
calm, intentional interiors
a seamless connection to the outdoors
Your home should feel effortless, not over‑designed.
Common Addition Types We Design
Every home is different, but most projects fall into one of these categories:
Rear additions for expanded living, dining, or kitchen space
Second‑story additions for growing families
Side additions for offices, mudrooms, or expanded circulation
Kitchen expansions that open the home and improve flow
Primary suite additions for privacy and comfort
Whole‑home reconfigurations to modernize outdated layouts
Split‑level modernizations to create openness and clarity
Mid‑century additions that respect original character while improving function
If your home feels tight, chopped up, or disconnected, you’re in the right place.
Budgets for Modern Additions
Every site and scope is unique, but most modern additions in the DC metro area fall within:
$300–$450 per square foot for typical modern additions
$450–$550 per square foot for complex structural changes or premium materials
$550+ per square foot for second stories or major whole‑home transformations
We help you align your vision with a realistic budget early — before design begins.
The First Step: The Modern Vision Assessment (MVA)
Additions are complex because they involve:
zoning and setbacks
lot coverage limits
structural constraints
existing conditions
budget alignment
integration with the existing home
The MVA is a focused 10–14 day pre‑design study that clarifies:
what your property allows
what your budget can achieve
the smartest way to expand
layout opportunities
potential constraints
a clear path forward
You’ll know exactly what’s possible before committing to full design.
