Know what the house can support before committing to construction

Home Addition Feasibility Studies

A feasibility study turns an early idea into a decision that can be tested. Dena House works with people who already own a home and with buyers evaluating a property before purchase. We spend time understanding how the household needs the property to work, then study the existing building, site, zoning, structure, systems, likely construction path and investment case together.

Completed residential construction evaluated through coordinated planning

A successful project resolves the work behind the walls with the same care as the rooms you see.

The process typically takes about two months. Technical feasibility and economic feasibility develop side by side, because a design that can be permitted but cannot support the owner’s budget or long-term goals is not a useful answer. When the direction remains promising, we can advance into architectural and engineering plans, detailed trade budgeting, material specifications and a realistic project timeline.

Scope

What home addition feasibility studies includes

01

Owner goals and property review

We document the household program, timing, budget range and ownership decision. For a property under consideration, the study focuses on the information needed before purchase as well as the implications of future work.

02

Survey and existing conditions

Scope can include boundary and topographic surveys, measurements, permit-history review, zoning screening, grades, drainage, access, utilities, structure and the condition of major building systems.

03

Technical and economic analysis

We compare plausible concepts against setbacks, lot coverage, load paths, roof and foundation work, permitting, construction logistics and market context. Budget and return-on-investment scenarios are treated as decision tools rather than promises.

04

Plan, specifications and roadmap

For a promising direction, the next deliverables can include coordinated architectural and engineering plans, material specifications, a detailed trade budget and a milestone-based design, permit and construction timeline.

Budget

What drives the investment

01

The study is scoped around the questions that must be answered. A straightforward property with a current survey and clear program requires less investigation than a sloped site, an older house with limited records or a purchase decision with a short contingency period.

02

Surveying, engineering and specialty investigations are identified rather than buried in a general allowance. Boundary and topographic surveys, structural review, utility research, soils or drainage input may be appropriate depending on the property and proposed work.

03

The value of the study is avoided uncertainty. It gives the owner a documented basis for moving forward, revising the program, negotiating a purchase or deciding that the project should not proceed before far larger design and construction commitments are made.

Working timeline

Plan in phases, with time for decisions.

These are planning ranges rather than promises. Address, scope, design completeness, review agencies, procurement and concealed conditions all affect the actual schedule.

Weeks 1–2

Discovery and survey

Owner interviews, document collection, property walk, measurement and coordination of any boundary or topographic survey.

Weeks 3–5

Analysis and options

Zoning, site, structure, systems, concept options, construction implications and economic scenarios are developed together.

Weeks 6–8

Decision package

The preferred direction is documented with next-step plans, budget structure, material assumptions, risks and a realistic timeline.

Before design advances

Three planning decisions to make early

  1. Gather the survey, listing information, inspection reports, permit history and any prior drawings before the first property review.
  2. Write the household needs separately from the preferred design. Multiple layouts may satisfy the same underlying goals with very different cost and risk.
  3. Set both an investment range and a decision deadline. The study can then focus on the information that matters most to ownership or purchase timing.

Questions we hear

Home Addition Feasibility Studies FAQ

Can you study a house before we buy it?

Yes. We work with prospective buyers as well as current homeowners. The scope and schedule are organized around the available documents, property access and any purchase-contingency deadline.

Does the study include a survey?

Boundary and topographic surveys can be included and are often important for additions, grading, drainage and setback analysis. We coordinate the survey scope with the questions the project needs to answer.

How long does the process take?

A complete feasibility study typically takes about two months. Property access, survey availability, agency records and the number of concepts can affect the exact schedule.

Will we receive construction drawings?

The feasibility phase establishes a defensible direction. If it remains promising, Dena House can continue into coordinated architectural and engineering plans suitable for detailed pricing and permit development.

Is ROI guaranteed?

No. Economic feasibility uses current information and explicit assumptions to compare scenarios. It is not an appraisal or a guarantee of construction cost, financing terms or resale value.
