Additions & Conversions Ideas
Addition and conversion ideas here explore how underused or new space could work — garage, attic, basement and extension directions — as planning inspiration, not feasibility guarantees.
Educational concepts only — not structural, permit, engineering, cost or feasibility advice. What is possible varies by building and local rules; confirm with qualified professionals.

Each idea is an educational planning direction and a set of questions to confirm with qualified professionals.
Garage-To-Living-Room →A concept for turning an underused attached garage into an everyday habitable room that flows with the rest of the home; owner-side points to confirm locally.Garage-To-Office →A concept for converting a garage into a quiet, semi-separate home office with its own access and work-ready services; owner-side questions to confirm locally.Attic Bedroom →A concept for converting under-roof attic space into a calm bedroom retreat; owner-side questions on headroom, access and escape to confirm with professionals.Attic Office →A concept for turning attic volume into a light, quiet home office away from household bustle; owner-side questions on access, daylight and services to confirm.Loft Conversion Direction →A framing concept for weighing broad loft conversion directions early — roof-light, dormer or larger changes — as owner-side questions to explore.Basement Living Space →A concept for turning a basement into comfortable habitable living space; owner-side questions on daylight, ventilation and moisture to confirm.Basement Utility Zone →A concept for using a basement as a practical utility, laundry and storage zone rather than habitable living; owner-side damp and services questions.Cellar-To-Room →A concept for converting an older masonry cellar into a usable room while respecting its age, damp behaviour and low ceilings; owner-side questions to confirm.Integral Garage Rework →A concept for reworking an integral garage within the home's footprint into usable interior space; owner-side structure, elevation and parking questions.Dormer Loft Direction →A concept for adding a dormer to a loft to gain standing headroom and usable floor area; owner-side questions on appearance, structure and permissions.Roof-Light Loft →A concept for a loft direction that keeps the existing roofline and brings daylight through roof windows within the current volume; owner-side questions.Loft Staircase Access →A concept for how a new staircase could reach a loft and what it takes from the floor below; owner-side questions on position, headroom and rules.Headroom & Access Questions →A question-framing concept to structure early headroom and access questions before any conversion, to explore with qualified professionals and authorities.Single-Storey Extension →A ground-floor-only extension idea focused on choosing which direction to grow and how to bring daylight in; feasibility and permissions to confirm locally.Side-Return Infill →A side-return extension idea that infills the narrow strip beside a house to widen a room; daylight and tight-boundary questions to confirm locally.Rear Extension →A rear extension idea that grows the house into the back garden, weighing added indoor space against garden depth; permissions to confirm locally.Wrap-Around Extension →A wrap-around extension idea combining side-return and rear footprints into an L-shape; a larger, more complex plan with questions to confirm locally.Two-Storey Extension →A two-storey extension idea that stacks added space over two floors to gain rooms above and below; structural and permission questions to confirm locally.Sunroom / Garden Room →A light-focused sunroom or garden-room addition idea that maximises glazing and garden connection; year-round comfort questions to explore and confirm.Porch / Entry Addition →A porch or entry addition idea that adds a sheltered threshold and draught lobby at the front door; a modest footprint with local permission questions.Over-Structure Addition →An idea for adding a room above an existing garage or single-storey structure; whether the base can carry new load is a question for a structural engineer.Granny Annexe →A self-contained annexe idea for multigenerational living, balancing independence with connection; separate-dwelling and permission rules to confirm locally.Outbuilding to Room →A conversion idea turning a detached garage or outbuilding into a usable room; upgrading an unheated shell for comfort, with approvals to confirm locally.Modular / Container Room →An idea exploring a prefabricated modular or container-based room delivered to site; siting, foundations and connection questions to confirm with professionals.Knock-Through Connection →An idea about how an extension joins the existing house — the opening between old and new and the open-plan flow it creates; structural questions to confirm.Extension–Garden Link →An idea about the threshold between an extension and the garden — glazed doors, level transitions and indoor-outdoor flow; drainage detail to confirm locally.
