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 how an addition meets the actual condition of existing material.
Which trade-off matters?
Full renewal creates a uniform appearance, while targeted repair preserves more existing material. Compare both using a sample area and assess technical compatibility too.
What the drawing needs to explain
Mark intact, damaged and unassessed areas on photographs. Add the old-to-new junction detail with proposed materials and treatment.
Decide this before construction
Start with a survey and trial repair, reviewing the result before treating the whole surface. Protect retained elements while removing adjoining material.
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.
