A deck outside an accessory dwelling unit can give it a place for morning coffee, a meal, or a comfortable step into the yard. The planning question is how that space belongs to the ADU while working with the main house and the people who share the property.
BigDecks designs and builds real-wood decks and connected outdoor spaces in Austin and Central Texas. Start an ADU deck conversation with the entrances, paths, privacy, and daily routines on both sides of the yard.
Map the routes used by both households
Draw the ADU and main house on a simple sketch. Mark how people arrive from the street or driveway, reach each entrance, take out bins, and move through the yard. Add the places used for parking, deliveries, equipment, or shared storage.
Decide which routes should remain shared and which seating areas should feel separate. A path to a bin or utility area should be considered before a table, screen, or deck edge occupies that space. Use your actual furniture dimensions where available so the layout can be reviewed with chairs in use.
Review the ADU entrance and ground level together
Photograph the doorway, the ground below it, and the approach from the yard. Show the door swing, any existing steps, changes in level, and nearby building features. Explain any access needs of the people who will use the entrance.
Ask the project team to assess the transition between the doorway, deck, and ground before settling the footprint. Connections, support, steps, guards, drainage, and accessibility requirements depend on the actual building and site. A reference photo or a surface-board size is not a construction detail for your ADU.
If the plan reuses an existing landing or deck, include its condition and the proposed connection in that assessment.
Look at privacy from inside both homes
Consider the views from the ADU doorway and windows as well as from the main house. Then look from the proposed seats on the deck. These viewpoints can lead to a different layout than one chosen only from a plan overhead.
Discuss whether privacy comes from placement, a wood or steel fence, a screen, planting, or a combination. Review the effect on daylight, views, access, and the remaining yard. A screen should have a defined role rather than being added after the seating area is fixed.
For an ADU occupied by someone else, agree how the outdoor area will be used and cared for. Include who may use the deck, how guests arrive, and which routes need to stay shared.
Confirm the property information and approvals
Bring any available survey, site plan, and ADU approval documents to the project discussion. Identify property boundaries, easements, trees, utilities, and existing improvements that may affect the deck or access for construction.
Ask which jurisdiction governs the work, what the existing approvals cover, and what additional review the proposed deck requires. Agree who will prepare applications and obtain required approvals. Include any applicable association or shared-property permissions. Resolve these questions for the actual project before construction proceeds.
Compare real-wood surfaces within the proposed layout
BigDecks OG 4×12 is the flagship surface-board arrangement in Douglas fir or Western red cedar. The little g uses 2×10 surface boards in those same species. Compare their proportions in the design instead of assigning one profile to small decks and another to large ones.
Standard Decks is the secondary entry option, with pressure-treated pine structure and surface, ring-shank nails, and an unfinished base. Finish is selected separately. Ipe and thermally modified wood are also real-wood options to discuss for the intended application.
Review the proposed wood, finish, and care expectations with the house and surrounding yard. The small-backyard deck planning guide explains how furniture, routes, and board proportions can be considered together.
Put the connected work into one clear brief
List any fence, shade, path, planting, stonework, or outdoor bathing element you want to consider with the deck. Show how the spaces should connect and identify anything intended for a later phase.
Design Assist develops the layout and details for the property and the way you want to use it. Confirm the applicable design package and construction scope for your project; a straightforward single deck may not need paid Design Assist. Design work and a written construction quote serve different purposes.
Use the deck planning estimate to begin a budget conversation, with other work identified separately. Send my project & estimate with your sketch, photographs, and priorities. John reviews the inquiry and arranges any site visit needed for a written project quote.
