One team or two firms: how DFW proposals really compare

Two bids for the same DFW property can look tidy on paper and still mislead you. One proposal may come from an integrated team; the other from a specialist landscape design company. If the scopes split at the house-to-yard boundary, neither total may price the coordination, licensing, and liability work that boundary requires. Texas law separates interior design, landscape architecture, and architecture into distinct licensed scopes, so the interface between building and site is not a cosmetic detail. It is a regulatory and contractual handoff that someone must own in writing.

This comparison explains why two bids for one property rarely compare, where scope overlaps and gaps appear, and how licensure, registration, and insurance boundaries shape responsibility. You will see where interior design scope legally stops, where landscape architecture reaches the building, and which carve-outs become your gap list. We will then focus on who owns coordination in writing and how to price the risk with a fill-the-gap re-total method. The cheaper bid is the one that prices the boundary, not the one with the lowest total.

Two proposals for one DFW property, and the gap neither one prices

Two proposals sit on your kitchen table in Highland Park. One arrives from a landscape design company. The other arrives from an interior designer who has brought in separate outdoor living space designers to cover the yard. Each carries a confident total, and each reads as complete.

You already feel the problem. The totals differ by a number you cannot account for, and the line items look similar enough that you assume the difference is markup. It usually is not. It is missing work.

Split-scope proposals leave the interface between house and yard unpriced. That interface sits on a licensing boundary, not a matter of taste, since work at the threshold can cross into a licensed scope and Texas treats unlicensed practice as an enforcement priority.

Shift the axis. Compare the two bids on coordination responsibility rather than total fee, and the ranking often reverses. The smaller total frequently belongs to the proposal with the larger unassigned gap, which is why integrated interior and landscape design matters more here.

The framework ahead is the one we use at Avesso Studio. It moves through scope overlap, scope gaps, coordination ownership, licensure, and insurance, then re-totals both bids on identical scope. Start where landscape and interior meet, because that threshold is where the money hides.

Why two bids for the same property rarely compare

Each proposal is priced against its own scope definition, not against yours. Two identical totals can therefore describe very different amounts of work, and a shared headline number tells you almost nothing. That is not a new problem: poor scope definition at the time of budgeting has ranked as the highest-impact cause of projects running over budget for decades, and the finding has held through every subsequent review.

The boundary effect carries the rest. A proposal that stops at the foundation or the fence line excludes everything past that line, including the details that make the two halves function as one space. Duplication is the visible error, because you can see the repeated line item and negotiate it down. Omission is the quiet one. Work nobody was assigned returns later as a change order, priced at the moment you have the least leverage.

Rebuild the comparison around one question: which document assigns the interface work to a named party, and what does that assignment cost? Ask both firms in writing.

Until you have that answer, evaluating a landscape design company on fee alone compares a scope you can see against a scope you cannot. That is why the next step is to read both scopes side by side and mark what each one already includes.

Scope overlap: what both proposals already include

Both proposals will cover concept development, material selection, planting or finish specification, lighting, and a construction set for their own discipline. That overlap is structural, not sloppy. ICOR's Practice Overlap Guidance, dated November 2025, classifies materials, contract documents, construction administration, and project integration as areas of collaboration, so both sides legitimately carry them.

Overlap is normal and usually the lesser problem. A duplicated planting plan costs less to reconcile than an unassigned retaining wall detail costs to build. Watch for the same item priced twice under two names. Site lighting is the common one, appearing in both the interior package and the landscape package.

The overlap question is not who wins the line item. It is who reconciles the two drawings when they disagree at the threshold, and what that reconciliation costs. Different teams may unknowingly work from different drawing versions, and that construction administration effort is often absorbed rather than scoped, which means it appears on no invoice until it appears as a delay.

Overlap is where you can negotiate. Gaps are where you cannot.

Scope gaps and the licensing line

Overlap is negotiable. Gaps are not, and the reason your two proposals do not line up is statutory.

Texas separates interior design, landscape architecture, and architecture into distinct licensed scopes. Read the statutory definitions in Occupations Code Chapter 1051 as a map of what each proposal can and cannot cover. Then mark every item the chapter excludes.

Cite the statute, not a summary of the regulator. Language describing the Texas Board of Architectural Examiners explains the board's purpose, public protection, and does not define the boundaries of practice. The boundaries live in Chapter 1051, and every scope and carve-out claim you evaluate should trace back to it. The definitions and the exemptions sit in separate subchapters of that same chapter, which is why a scope can read broadly and still stop short of the work your property actually needs.

That distinction is practical. The carve-out list is your gap list. An item excluded from landscape architecture scope and absent from the interior package is unassigned, and unassigned work returns as a change order at the moment you can least afford it.

Frame the conclusion structurally. A split-scope bid is not wrong. It is incomplete until someone prices the boundary.

Where interior design scope legally stops

Texas Occupations Code Chapter 1051 gives you the edge in writing. The statute defines interior design to include space planning of non-load-bearing interior construction, along with the preparation of an interior design plan, specification, or related document about the design of a non-load-bearing interior space.

Read the qualifier as a boundary, not a formality. Non-load-bearing is the statutory line. Anything structural or load-bearing falls outside interior design scope, a limit that shapes what full-service interior design actually includes.

For your proposal review, this matters in one practical way. If an interior bid reaches past that line, another licensed professional has to stand behind the work. That professional is a cost line in the budget, not a courtesy the other firm absorbs. A bid that stops at the boundary without naming who covers the structure is incomplete, not inexpensive.

Rome leads interior scope up to that boundary on every project. That handoff shapes what to expect from a Lakewood interior design project, where the house and yard are designed as one composition. The boundary is also where a landscape design services proposal has to pick up cleanly, and that assignment belongs in writing rather than in a verbal assurance.

Where landscape architecture reaches the building

The boundary cuts both ways. Landscape architecture reaches back across it, and Texas Occupations Code Chapter 1051 supplies the statutory basis. The definition places integration, site analysis, and determination of the location of buildings, structures, and circulation and environmental systems inside the practice. Buildings and structures, not plantings alone. The chapter also names collaboration with other professionals in the design of roads, bridges, and structures regarding functional, environmental, and aesthetic requirements. Read together, those clauses establish a landscape scope in Texas that legitimately touches the house rather than stopping at the yard. That is why a serious landscape design services scope can carry details that decide how the threshold performs, from grade and drainage at the door to the paving, shade, and planting that make an outdoor room usable. Our FAQs about luxury landscape design in Dallas walk through how those decisions land on a real property.

The same chapter then lists design coordination and review of technical submissions, plans, and construction documents prepared by persons working under the landscape architect's direction. Read that clause slowly. In Texas, coordination is a defined professional service, not an add-on you hope someone performs out of goodwill. At the interface, that distinction is the whole argument, and it shapes how space layout and landscaping for outdoor views get resolved on paper before anyone breaks ground.

The carve-outs that become your gap list

Even a scope that reaches the building has a statutory perimeter. Texas Occupations Code Chapter 1051 excludes several functions from landscape architecture outright.

The list reads plainly. It excludes traffic, roadway, or pavement engineering. It excludes the design of utilities. It excludes the engineering or study of hydrologic management of stormwater systems or floodplains. It excludes the making of final plats. It excludes any service or function within the practice of architecture, engineering, or public surveying.

Treat that list as your checklist. If a carve-out item appears in neither proposal, it is unassigned. In our experience, unassigned work returns as a priced change order, typically when the site is open and your leverage is lowest. That pattern is the reason this gap is structural rather than a mistake either firm made. Split-scope bids often stop exactly at these statutory lines, because each firm prices what its license clearly covers and steps back from the rest. The result is a clean proposal with an unpriced boundary between house and yard.

Your next question is who owns that boundary. That is coordination, and in Texas it has its own statutory definition.

Who owns coordination, in writing

The carve-outs tell you what is unassigned. The next question is who answers for the work that spans them, and the answer belongs in the contract, not the presentation.

Ask each firm directly: who holds coordination responsibility, and which clause assigns it? Texas Occupations Code Chapter 1051 names design coordination and review of technical submissions, plans, and construction documents prepared under the landscape architect's direction as professional services. That clause sets the standard. Coordination is a deliverable, not a courtesy. An answer that describes goodwill, weekly calls, or a good working relationship does not meet it.

In a two-firm arrangement, coordination usually sits between the contracts. Neither document names the person who reconciles two drawing sets at the threshold, so nobody is accountable by default. The coordination gap is where projects fall apart.

Request three things in writing: a named individual, a schedule for coordination meetings, and a documented process for resolving conflicting drawings at the threshold. AIA Contract Documents and Texas Society of Architects guidance exist for this purpose, giving you concise scope descriptions that prevent disagreements and delays.

An integrated team answers differently. One document defines interior scope and landscape scope together, so the interface has one owner. Rome holds interior scope to its non-load-bearing boundary. Daniel holds landscape scope, including coordination. Under one contract, review of technical submissions happens inside the team that drew them.

Licensure and registration: a verification step, not an accusation

Coordination ownership is a question you can settle in writing. Registration is a question you can settle with a lookup.

The Texas Board of Architectural Examiners is the single state agency that examines, registers, and regulates architects, registered interior designers, and landscape architects. Its stated purpose is public protection: safeguarding health, safety, and welfare by holding licensed professionals to established standards. Texas Occupations Code Chapter 1051 carries the scope definitions and carve-outs discussed above. Read the board as the regulator, not as a professional society advocating for its members.

Before you sign, run two checks, because they answer different questions.

First, verify each named design professional through the TBAE design pro verification tool. Second, check the business or firm registration portal. An individual's registration and a firm's registration are separate statuses, and a proposal can list a registered designer while the entity contracting with you is not registered at all.

TBAE also publishes disciplinary actions, complaints and enforcement FAQs, and an Architect Required? flowchart dated February 2024. An interactive version walks you through when a project needs an architect. If your property involves structural change, that test is worth five minutes.

The lookup takes minutes. It confirms that the names on your contract hold the credentials the work requires. Registration settles who may practice. It does not settle who pays when something goes wrong. That is an insurance question, which comes next.

Insurance and liability: the questions to put in writing

Registration tells you who may practice. It does not tell you who pays when the boundary fails. That takes four questions, all in writing.

Ask each firm what professional liability and general liability coverage it carries. Request the certificates of insurance, not a verbal summary. A certificate is the document of record. A proposal narrative is not.

Ask which scope each policy responds to: design errors, construction administration, or site conditions discovered during the build. A firm that describes coverage only in general terms has not answered the question your property depends on.

Ask who carries coverage for the interface work, meaning the drawings and details where the interior scope and the landscape scope meet. No industry standard assigns this by default, so the answer has to come from the firms themselves.

Ask how the two policies interact if a claim touches both scopes, and which carrier responds first. Ordering of coverage is a contractual mechanism. You want it stated before work begins, not negotiated after a loss.

Do not read a total fee as evidence of coverage. The lower bid can carry the thinner policy, and the proposal will not say so. The certificate answers this question and the proposal does not.

This is the least standardized part of a two-firm comparison. Limits, forms, exclusions, and deductibles vary by firm, owner, and project size. Written answers, signed and dated, are the only version you can hold anyone to.

Pricing the risk: a fill-the-gap re-total method

You have the certificates and the written answers. The last piece is arithmetic, and it begins by refusing to compare the two totals you were handed.

This re-total method is our framework, not an industry standard. It works because it forces both proposals onto a single scope.

Step one. Build a gap register. List every carve-out item from Chapter 1051 alongside every interface detail in both proposals, then mark each one assigned, duplicated, or unassigned. Duplicates cost less than you fear. Unassigned items are the number you are missing.

Step two. Price the unassigned. Ask each firm for a line item on the boundary work: the threshold details, the grading at the foundation, the drainage that touches both scopes. If neither firm will quote it, bring in a third quote.

Step three. Add coordination. Count the hours someone will spend reconciling drawings, schedules, and site conditions. In a two-firm arrangement, that labor typically sits in no one's fee, because no one owns it.

Step four. Re-total. Put both proposals on the same scope basis and compare the numbers side by side.

Step five. Pressure test. Ask what happens when the boundary work changes. Change orders price the gap at the worst possible moment, mid-build, with a crew standing on the property.

The method produces one conclusion. The cheaper proposal is the one that prices the boundary, not the one with the smaller total.

What owning the interface looks like in practice

Once you re-total both bids on identical scope, the gap has a number. The remaining question is who was ever going to own it. In an integrated model, one studio holds interior and landscape scope under a single contract, which is how we work at Avesso Studio.

Bryan shows the model at work. Interior and landscape decisions there resolve together at the threshold, in one conversation, rather than being negotiated between two firms that each stop at their own drawing edge. The relationship between interior and landscape is not a handoff in that house; it is one design decision seen from two sides.

Oscar shows the coordination clause exercised directly. Review of technical submissions happens inside the same team that drew them, so the person checking the detail is the person who detailed it. Nothing sits between two contracts.

Silver Leaf and Country Club show the sequence. Outdoor rooms in both follow the interior program instead of running beside it, which is the difference between landscape design & build that answers the house and work that merely adjoins it.

Rome leads interior scope up to its statutory non-load-bearing boundary. Daniel leads landscape scope, including coordination, and the interface has one owner in writing.

Keep the claim modest, though. An integrated team removes an interface. It does not remove risk. Permits, site conditions, and weather still do what they do. What changes is that nobody has to discover, mid-build, that a boundary detail belonged to no one.

A checklist for your next proposal review

An integrated team removes one interface. Every proposal review still deserves the same rigor, whether you weigh one contract or two. Bring this list to your next meeting.

Scope in writing, exclusions included. Each proposal should state what it covers and what it explicitly leaves out. An exclusion you can read is a decision. An exclusion nobody wrote down is a future change order.

A named coordination owner. Ask who holds coordination and where the contract says so. Require an individual's name, not a firm's, and ask how conflicting drawings at the threshold get resolved.

Registration, verified twice. Confirm every individual through the TBAE design pro verification tool, then confirm the firm through the business registration portal. A registered designer and a registered firm are separate statuses. Both matter.

Insurance, in certificates. Request certificates of professional liability and general liability from each firm, plus a written answer on which scope each policy responds to. A total fee tells you nothing about coverage.

The carve-out list, marked. Pull every Chapter 1051 carve-out item and interface detail from both proposals. Mark each assigned or unassigned before you negotiate, because unassigned work returns priced.

A like-for-like re-total. Rebuild both bids on identical scope, then compare fees. Finish by asking what the number looks like after a change order. That answer prices the boundary.

Run the list once and the comparison usually resolves itself.

The cheaper bid is the one that prices the boundary

The checklist ends where the negotiation begins, and one question remains: which proposal names the boundary?

Two bids for the same DFW property rarely describe the same work. One prices landscape design services to the foundation; the other prices the interior to the threshold. Neither prices the detail where they meet. Total fee is therefore the least useful number on either page, because it measures different scopes.

Run the five steps. Mark every Chapter 1051 carve-out and interface detail as assigned, duplicated, or unassigned. Price the unassigned items. Cost the coordination hours someone will spend reconciling drawings, schedules, and site conditions. Re-total both proposals on identical scope. Then pressure test the result: ask what the number becomes when the boundary work changes, because a change order prices the gap at the worst moment.

Get written answers to two more questions. Who owns coordination, named in the contract rather than described in the presentation? Which insurance policy responds when a claim touches the interface work? Verify registration for every individual and the firm through the Texas Board of Architectural Examiners before you commit.

You pay for the boundary either way, through a line item now or a change order later. The proposal that names it in writing usually costs less by the time the property is finished. At Avesso Studio, Rome and Daniel work under one scope, so the boundary gets named.

Conclusion

Two DFW bids can look comparable while pricing different scopes. The real gap lives at the boundary: Chapter 1051 carve-outs, interface details, coordination, insurance, and registration. Mark every item assigned, duplicated, or unassigned, price the unassigned work, and re-total both proposals on identical scope. Then get written answers: who owns coordination, which policy responds, and who is verified with the Texas Board of Architectural Examiners. The cheaper bid is the one that names the boundary before you sign. Run the checklist, ask the hard questions, and choose the proposal that prices the interface in writing. At Avesso Studio, Rome and Daniel work under one scope, so that boundary gets named.
