A landscape design project in Denver takes weeks to months from first meeting to finished plans, and the pace depends more on your decisions, your site, and outside reviews than on drawing time. Ivy Street Design, a Denver landscape architecture and design firm that has designed Denver metro landscapes since 1992, explains what sets the clock and how to keep it moving.

Quick Summary

• Design and construction run on two separate clocks. Design finishes first, then a builder is chosen and scheduled.
• No firm can promise a single number before seeing your property. Yard size, features, and slope all change the answer.
• Your own decision speed is the biggest factor you control.
• Steep sites and designs near property lines may need a site survey, which adds a step.
• Denver requires zoning permits for some walls and fences, and extra review in historic areas.
• Designing in winter lets you build as soon as the ground thaws.

How long does a landscape design project take?

Design alone usually takes a few weeks to a few months, depending on yard size, how many features you want, and how quickly you give feedback. Construction is a separate clock that starts after the plans are done and a builder is chosen. No honest firm can promise one number before seeing your site.

The useful question is not "how many weeks" but "what decides the weeks." Ivy Street Design designs outdoor living spaces, hardscape, planting, lighting, and sloped yards across the Denver metro. A simple front entry planting moves quickly. A full backyard with a patio, fire feature, lighting, and grade changes needs more decisions, more drawings, and more coordination.

What are the phases, and which one takes longest?

A project moves through design, review, bidding, and construction. Construction is usually the longest phase, because building takes time on site. Design is usually shorter, but it is the phase where your choices shape every later date. Each phase has its own drivers.

• Design. Site analysis, the 3D presentation, revisions, and construction documents. This is the phase you influence most through quick, specific feedback.
• Review and permits. Needed for some walls, fences, and structures, and for some neighborhoods or HOAs. Timing depends on the reviewing office, not on your designer.
• Bidding. Contractors price the finished plans. Clear drawings let them price the same scope, so you can compare bids fairly.
• Construction. Length depends on scope, site access, materials, and weather.

Ivy Street Design offers both design-only and design-build service, and the model changes how these phases hand off.

What speeds up or slows down the design phase?

Four things move the design schedule most: how fast you decide, whether the scope stays fixed, how complicated the site is, and how many people must approve. Drawing time is rarely the bottleneck. Waiting on a decision or a missing piece of information usually is.

• Slow or split decisions. If two people must agree and they review separately, each round takes longer. Pick one point of contact if you can.
• Scope changes late in design. Adding a fire feature after the 3D presentation means redrawing and repricing. Decide your must-haves early.
• Site conditions. Slopes, drainage, and tight lots take more analysis. CSU PlantTalk lists climate, topography, soils, and microclimate as part of the site inventory and analysis step, and each one feeds the plan.
• A site survey. Some properties need precise topography and boundary data first. Steep sites and designs near property lines are the usual reasons.
• Revision rounds. Specific notes ("move the seating 4 feet toward the fire feature") resolve in one round. Vague notes ("make it feel better") take several.

CSU PlantTalk notes that planning out your yard can save you time, money and back aches down the line. Time spent on analysis early is usually time saved in revisions later.

Do permits and reviews add time in Denver?

Yes, for some projects. The City and County of Denver requires a zoning permit for fences over four feet and for walls over 12 inches, retaining walls included. Historic districts, landmarks, and parkways add review at any height. Permit review runs on the city's schedule, so plan for it.

The City and County of Denver's fences and walls page sets out the rules we opened for this article:

• Zoning permit. Fences over four feet and walls over 12 inches, including retaining walls.
• Building permit. Most other fence and wall types over four feet. Masonry and retaining walls over six feet require commercial engineering plan review and a building permit.
• Historic and parkway areas. A permit is needed for fences and walls of any height in a historic district, on an individually designated landmark, or along a designated parkway.
• Floodplain and sewer lines. A sewer use and drainage permit may be required in a floodplain or when digging within two feet of a sewer line.
• What you submit. An online application with a site plan showing lot lines, setbacks, and the location, height, and materials of the proposed wall or fence, plus section and footing details for permit-required walls.

The page does not state how long review takes, so ask the reviewing office for current timing. Other cities and counties in the metro, and many HOAs, have their own rules, so check with the one that covers your address. If your project includes terraces or walls, our retaining wall planning guide covers what to settle first.

When should you start so you can build in spring?

Start design in fall or winter. Plans finished while the ground is frozen let you bid the work and book a builder so construction can begin as the ground thaws. Starting in spring means design, review, and bidding all happen before any building can begin.

Winter is design season in Colorado because drawing, review, and bidding do not need thawed soil. Our guide to when to start a landscape project in Colorado walks through a winter-to-spring plan. Builders' calendars tend to fill as spring arrives, so finished plans in hand give you a better chance at an early slot.

How can you keep your project on schedule?

Come prepared, decide early, and ask for dates in writing. Most delays come from missing information or late changes, not from the design work itself. Clear goals at the first meeting, quick answers between presentations, and an early look at city and HOA rules protect your timeline better than any rush request. A few habits help.

• Bring your goals and a budget range. They set scope at the first meeting. Our guide to what landscape design costs in Denver explains what drives fees.
• Collect inspiration photos and a likes and dislikes list. Plants, materials, and colors you want to avoid save a revision round.
• Name one decision maker. Or agree in advance how you will resolve disagreements.
• Give specific feedback. Point to the exact feature, location, or material.
• Check HOA and city rules early. Start any required review as soon as the plan allows.
• Ask for a timeline in the proposal. A good proposal states scope, budget, and expected dates.

Does design-build change the timeline?

It can. With design-build, one firm designs and builds, so the handoff between design and construction is shorter and there is no separate bid round to run. With design-only, you take the plans to bid. Both work, and the right choice depends on how much control you want over builder selection.

Frequently Asked Questions

How long does landscape design take before construction can start?

It depends on yard size, scope, and how quickly you respond. Design usually takes weeks to a few months, followed by any permit review and bidding. Ask your designer for a written timeline once the scope is set.

Can I speed up my landscape design?

Yes. Give clear goals at the first meeting, respond to each presentation quickly, and keep your wish list stable. Specific feedback on the 3D presentation shortens revisions more than anything else.

Do I need a permit for a backyard wall in Denver?

Often, yes. Denver requires a zoning permit for walls over 12 inches, including retaining walls, and a building permit with engineering review for masonry and retaining walls over six feet. Confirm your case with the city before you build.

Why does a sloped yard take longer to design?

Slopes need more analysis of drainage, access, and grade changes. A site survey may also be needed for precise topography. That work comes before terraces, steps, and walls are drawn, so the plan handles water and grade correctly.

Is winter a good time to design a landscape in Denver?

Yes. Design, review, and bidding do not need thawed ground. Finishing plans in winter lets construction begin as soon as conditions allow in spring.
