How we deliver construction at Salstan - Salstan Architecture
Our Approach

How we deliver construction at Salstan

Because we operate with an inhouse construction team delivering construction services London clients can depend on, we maintain tighter control over build quality, sequencing, and site standards. Design intent, technical detail, and on site delivery remain aligned throughout the project, reducing delays, rework, and uncertainty

Our civil engineering input supports the build from the outset, particularly on projects involving structural alterations, complex ground conditions, drainage strategy, or multi stage construction sequencing. This helps ensure the build is robust, compliant, and technically solved before key works begin on site.

Every project is managed with clear programming, practical milestone planning, and ongoing coordination. We keep the process structured and transparent, ensuring decisions are made at the right time and progress is monitored consistently.

How It Works

Our process explained in six easy steps

01
Your 3D Site Survey
An appointed surveyor visits for a full measured survey of your property. They will also note down all your desired requirements for the proposal.
02
Drawings Initiated
The project is allocated to one of our architectural designers who will design your project from the ground up, taking into account all your needs.
03
You Review It
Your first draft is typically ready in 7 working days, and within 10 unless agreed otherwise. Review the designs, send feedback, and we wrap up your drawing ready for submission.
04
Submission and Decision
Your plans are submitted strategically for swift approval by the council. Expect a decision in 6 to 8 weeks. We handle any required changes for free.
05
Technical Design
Once plans are approved, our engineers manage detailed design and regulatory compliance. Get construction quotes from us and compare with others.
06
Construction
If you move forward with our construction services, we arrange a detailed consultation to finalise your specific requirements, ensuring everything aligns with your vision.

Common Questions

Frequently Asked Questions

We deliver residential construction including kitchen extensions, rear extensions, side extensions, wrap around extensions, double storey extensions, loft conversions, and full house refurbishments with internal reconfiguration.
No. Our projects are delivered by our experienced inhouse team, supported by civil engineering input and project management to maintain quality, sequencing, and consistency on site.
Yes. We can support projects from early planning and design through technical detailing and construction delivery, ensuring the build is properly coordinated and build ready.
Quality is managed through disciplined sequencing, regular site oversight, and milestone checks that prevent defects being built in. We review critical stages such as structure, water proofing and weathering, thermal performance and airtightness, and drainage, then track workmanship through to final finishes and snagging. This approach protects long term performance, not just visual appearance.
Timeframes vary based on scope and complexity, but we set clear programmes and milestones at the start and manage progress throughout, keeping the build structured, transparent, and efficiently delivered.
