How long does a home addition take?

An addition happens in two phases: project development (design, engineering, selections, and permitting) and construction. Both depend on the size and complexity of the addition. You'll receive a construction schedule along with your contract, so you know what to expect before work begins.

Can we live at home while the addition is built?

In most ground-level additions, yes. The work stays largely outside until the new space is connected to the house. Second-story additions are more disruptive, and we'll talk through whether staying put makes sense for your household.

Do I need to hire an architect separately?

No. ELM designs your addition in-house and coordinates the structural engineer, so you work with one team from first sketch to final walk-through.

Can you match my existing brick?

In most cases, we can source brick that closely matches your home's original color and texture. When an exact match isn't available, we'll show you options, such as painted brick or a complementary material, during design.

Will an addition increase my home's value?

A well-designed addition that adds bedrooms, bathrooms, or functional living space generally increases a home's market appeal. The bigger payoff is often avoiding the cost and hassle of moving to a larger house.

What types of home additions does ELM build?

ELM builds ground-level and second-story additions for living, sleeping, cooking, and working. The most common projects we take on across the Over-the-Mountain area include:

Primary suite additions: A main-level bedroom, bath, and walk-in closet, often planned so you can stay in the home for decades.
Second-story additions: New bedrooms, baths, or a bonus room above the existing footprint, ideal for tight Homewood and Crestline lots.
Kitchen and family room expansions: Bump-outs that turn a closed-off kitchen into an open great room with space for an island and a dining table.
In-law suites and guest quarters: A private bedroom, bath, and kitchenette, with an optional separate entrance, for aging parents or adult children.
Four-season sunrooms: Fully heated and cooled rooms wrapped in windows that you can use in January and July alike.
Garage additions with living space above: Covered parking at ground level and an office, gym, or guest room upstairs.
Mudrooms and entry additions: A drop zone for bags, shoes, and leashes that keeps clutter out of the rest of the house.

Should you build up or build out?

The right direction depends on how much yard you have to spare and what your existing house can support. Here is how the two options typically compare:

  
      Ground-level addition
      Second-story addition
    
      Lot space
      Uses yard space; must clear setbacks
      Keeps the yard intact
    
      Foundation
      New foundation required
      Existing foundation and framing must carry the added load
    
      Disruption
      Mostly outside until the tie-in
      Roof comes off; more impact on daily life
    
      Best fit
      Main-level suites, kitchen expansions
      Small lots, extra bedrooms and baths

How we make an addition look original to the house

An addition that looks tacked on can hurt both curb appeal and resale value. Our designers model your home in Chief Architect and show you floor plans, exterior elevations, and 3D renderings before anything is built. That process lets us work through the details that make an addition blend in:

Rooflines and pitch: Matching or complementing the existing roof so the new mass sits naturally on the house.
Exterior materials: Sourcing brick, siding, stone, and trim profiles that match what's already there, or choosing a deliberate contrast when that suits the architecture better.
Floor and ceiling transitions: Aligning floor heights and weaving new hardwoods into existing ones so there is no awkward step or seam between old and new.
Windows and doors: Repeating the style, proportions, and grid patterns of your current windows.
Mechanical systems: Checking whether your HVAC, electrical panel, and water heater can serve the added space, or whether it needs its own zone or equipment.

How an addition comes together with ELM

First conversation: Tell us what you need the new space to do. We'll explain how our design-build process works and walk through our Budgeting Guide.
On-site discovery: We tour your home and lot, talk through priorities, and have a frank conversation about cost and timing.
Project development: We design the addition, coordinate structural engineering, guide your selections, and verify feasibility. You receive a detailed scope of work and a guaranteed fixed price.
Construction: We pull permits and build, planning the tie-in to keep your home weathertight and livable for as much of construction as possible.

What does a home addition cost?

A home addition's cost depends on its size, the foundation and structural work involved, how much plumbing it includes, and your finish selections. Kitchens, bathrooms, and second-story additions usually cost more per square foot than bedrooms or family rooms because of their added systems and structure. Our Budgeting Guide explains how project costs are determined, and your fixed price arrives before construction begins, with allowances clearly listed.

We are licensed (AL Home Builders License #21942) and insured, and our office is right here in Homewood.
