What this work involves
Separate what the plot allows from what you need in everyday life. A schedule of rooms helps coordinate architecture, building services and finishes from the beginning.
- Requirements and plot information
- Design, structure and investigations
- Construction system and materials
- Heating, energy use and ventilation
- Finishes, landscaping and handover documents
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
A complete budget includes more than the construction price. Keep design, investigations, connections, authority fees, landscaping and finishing choices visible.
Bring this to the discussion
Plot information, room requirements, existing drawings, preferred timing and budget priorities.
Questions about the work
When does a budget become reliable?
When the design, technical assumptions and finish level are sufficiently defined. Early estimates remain dependent on assumptions and provisional sums.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
