From Concept
— To Completion
Every project follows our structured six-stage process. Because TerraLine handles design, engineering, energy assessment, and construction in-house, your project benefits from seamless coordination at every stage.
PHASE_RESEARCH
Free Consultation & Feasibility
We begin with a free consultation to understand your vision, assess feasibility, and discuss budget and timescales. For extensions, conversions, and new builds, we visit the site to evaluate the existing property and identify any constraints. We advise on what is achievable under planning policy and permitted development rights.
PHASE_DRAFTING
Design & Planning Application
Our architects produce detailed drawings for planning submission. We prepare the full application package and submit on your behalf, managing all correspondence with the planning authority and responding to officer queries.
PHASE_COMPLIANCE
Structural Engineering & Building Regulations
Once planning is secured, our structural engineers produce calculations and building regulation drawings. We prepare the complete technical package and submit to building control. SAP calculations and energy assessments are completed at this stage.
PHASE_LOGISTICS
Condition Discharge & Pre-Construction
We handle the discharge of any planning conditions, prepare the site for construction, and coordinate pre-start requirements including party wall agreements, build-over agreements, and utility notifications.
PHASE_EXECUTION
Construction & Site Management
Our construction team takes over on site with a detailed build programme. We manage all trades, conduct quality inspections, and coordinate building control visits. You receive regular progress updates with a single point of contact throughout.
PHASE_DELIVERY
Completion & Handover
We carry out thorough snagging, obtain final building control sign-off and completion certificates, deliver as-built drawings, and provide all necessary documentation including final SAP assessment and EPC certificate where applicable.
TerraLine utilizes a unified in-house coordination model to provide seamless lifecycle management from initial site feasibility to final building control certification.
