Transforming Your Home with Expert Loft Conversions Across London
Looking to maximize your living space without the hassle of moving? An attic conversion is the perfect way to add value and functionality to your home. At TNK Construction Ltd, we specialize in high-quality loft conversions across all London boroughs, delivering exceptional craftsmanship with a seamless process. With over 17 years of experience, our CITB-accredited builders ensure each project is completed to the highest standards.
In this guide, we walk you through our step-by-step loft conversion process, so you know exactly what to expect when transforming your home with TNK Construction.
Step 1: Initial Consultation and Site Survey
The first step in any successful attic conversion is a thorough consultation and site assessment. Our team will:
Visit your property to assess feasibility.
Discuss your vision, requirements, and budget.
Evaluate structural integrity and roof type.
Identify any planning permission requirements.
At TNK Construction, we cater to homeowners across Central London, North London, and surrounding boroughs, ensuring a customized approach for every project.
Step 2: Planning and Design
Once the feasibility is confirmed, our expert designers will work on creating detailed plans for your loft conversion. This phase includes:
Drafting architectural plans tailored to your space.
Advising on loft conversion types (dormer, mansard, hip-to-gable, or Velux).
Maximizing space with smart design solutions.
Ensuring compliance with London building regulations.
For most loft conversions in London, planning permission is not required if the work falls under permitted development rights. However, if needed, our team will handle all necessary applications to make the process hassle-free.
Step 3: Structural Calculations and Building Regulations Approval
Before construction begins, our structural engineers conduct detailed assessments to ensure safety and durability. This includes:
Calculating load-bearing capacity.
Determining structural reinforcements needed.
Submitting plans for building regulations approval.
As a fully accredited London construction company, we ensure that every project meets the highest safety and regulatory standards.
Step 4: Construction and Build Phase
Once all approvals are secured, the exciting part begins! Our highly skilled builders and carpenters start the loft conversion construction, following a structured timeline:
Phase 1: Structural Work
Reinforcing floor joists for added stability.
Constructing dormers or altering roof structures (if applicable).
Installing steel beams for support.
Phase 2: Roofing and Insulation
Adding high-quality insulation for energy efficiency.
Roofing modifications and waterproofing.
Installing Velux windows or dormer windows for natural light.
Phase 3: Internal Work and Finishing
Installing partition walls and ceilings.
Fitting electrical wiring and plumbing for en-suite bathrooms (if required).
Custom-built staircases for easy loft access.
High-end carpentry and bespoke storage solutions.
Throughout this phase, our London-based project managers ensure smooth progress while keeping you informed at every step.
Step 5: Final Inspection and Completion
Before handing over your brand-new loft conversion, we conduct a thorough quality check to ensure everything meets your expectations. This includes:
A final building inspection to confirm compliance.
Snagging and final finishing touches.
Deep cleaning and handover.
Providing all necessary certificates (building regulations approval, electrical, gas safety).
At TNK Construction, customer satisfaction is our priority, and we take pride in delivering exceptional loft conversions across London with the highest attention to detail.
