What this work involves
A store and a room used every day have different needs. Define the use before selecting a building system, and consider the connection with the garden, house and existing paving.
- Use and required facilities
- Position on the plot
- Foundation, floor and moisture control
- Daylight, insulation and ventilation
- External materials and maintenance
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Assess an addition in the complete elevation, including existing roof lines.
Which trade-off matters?
Exact reproduction and a clearly contemporary addition are different design choices. Compare their junctions; an almost matching brick or profile can look less coherent than a carefully chosen contrast.
What the drawing needs to explain
Draw a scaled elevation showing existing and new windows together. Resolve the roof-edge, wall and window junction before deciding from an atmosphere image alone.
Decide this before construction
Photograph retained details before dismantling. Check the dimensions of new components against the actual facade before production begins.
Cost factors for this service
Dimensions, foundation, facade finish and services determine much of the cost. Water, drainage and electricity from the house may require additional work.
Bring this to the discussion
A plot sketch, site photographs and a description of the intended use.
Questions about the work
Can a garage become a living room?
That requires assessment of permitted use, moisture, insulation, daylight, ventilation and structure. Establish feasibility before choosing finishes.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
