Step 1: Quote & contract
Tell us what you need. Our designers put together drawings and an organized, easy-to-read quote, then work through the details with you until the building is yours.
Lean-tos and additions for the building you already have.
Open or enclosed lean-tos, extra bays and full additions, framed to tie into your barn, your shop or your business.
Room to grow, without starting over.
Most buildings run out of room before they wear out. A lean-to off the side gives you covered space for equipment, firewood or a porch; extra bays add length; and a full addition adds whole rooms, like the barrel room, laboratory and bottling room in the addition we built for Salted Vines Vineyard & Winery.
A lean-to’s low side stands on new posts and its high side ties into the existing frame, so the condition of that frame decides the design. We look at it, and at how water leaves the old roof, before anything is drawn.

Planning a lean-to or an addition.
Start with the building you have
The existing posts, trusses and roof decide what can tie into them. A new roof should carry water away from the old one, never into the valley between them, so the pitch and the height of the lean-to are worked out from the building it joins.
Open or enclosed
An open lean-to is the simplest way to get things under a roof. Walls, doors and a concrete floor turn it into working or storage space. Many owners start open and enclose it later, and the frame can be planned for that from the start.
Matching what’s there
New steel, trim and doors can match the old building closely, or set the addition apart on purpose. Steel colors and panel profiles change over the years, so we compare what’s on your building with what’s made today and talk through the closest match. If the old roof is tired, our metal roofing and siding work can redo it at the same time.
Permits and setbacks
An addition is new construction, so it needs a permit, and it has to meet the same setbacks from your property lines as any building. On a business it can also bring site plan and code requirements. We check what applies to your property and manage the permit.
Talking it through is free. Call the office and we’ll help you size it.

Three easy steps.
One team handles the drawings, the permits and the build, and keeps you posted the whole way.
Step 2: Permits
We manage the permits for you, wherever you live. Homes usually take 3 to 5 months to permit, depending on the county. Garages and farm buildings move faster.
Step 3: Construction
Our crews build it and our project managers keep you posted every step of the way. Final payment comes after the county’s final inspection.
Questions we hear about this.
Still wondering about something? Call us at 302-399-4420.
Can you add a lean-to to a barn someone else built?
Often, yes. We look at the existing posts, trusses and roof first, since the lean-to ties into them, and we tell you what the frame can carry before anything is drawn.
Do I need a permit for a lean-to or an addition?
Almost always. An addition is new construction, so the county or town wants a permit, and it has to meet the same setbacks as any building. We check the rules for your property and handle the permit.
Can you build an addition while my business stays open?
In most cases, yes. The new frame goes up beside the existing building and is tied in at the end, and we plan the work around your hours and access.
Can the new steel match my old building?
Usually closely. Steel colors and panel profiles change over the years, so we compare what’s on your building with what’s made today and talk through the closest match before anything is ordered.
