Flat Refurbishment

Q: How do you manage 'Licence to Alter' (LTA) and managing agent requirements?

Navigating the Licence to Alter (LTA) process is the most critical phase of a flat refurbishment. We provide the technical drawings, structural calculations, and insurance documentation required by freeholders. Our team ensures all works comply with the specific 'house rules' of your London or Essex building, including designated working hours and communal area protection.

Q: What measures do you take for fire safety and acoustic compliance?

In multi-unit buildings, fire compartmentation (Part B) and acoustic attenuation (Part E) are paramount. We install certified FD30/60 fire doors and certified fire-stopping. Every installation is documented to support your building’s 'Golden Thread', ensuring future property transactions aren't delayed by compliance gaps.

Modernise. Reconfigure. Comply.

We specialise in the high-stakes environment of multi-unit residential refurbishments across London and Essex. Tarj Construction manages the unique complexities of shared structures, ensuring your project meets strict fire safety, acoustic, and leasehold requirements without compromising on refined design.

Flats refurbished with technical governance and logistical control.

Refurbishing a flat requires a level of oversight far beyond a standard house renovation. From navigating Licences to Alter (LTA) with managing agents to ensuring Part B fire-stopping and Part E acoustic performance, every detail must be documented and compliant. We work with leaseholders, asset managers, and developers to deliver structured refurbishments that protect the building's integrity and your neighbours' amenity. Our approach ensures your project contributes to the 'Golden Thread' of building safety, making future property transactions seamless and secure.

Yes. We specialise in the structural engineering required for shared buildings. This involves precise propping, RSJ installation, and staged LABC inspections. We coordinate with structural engineers to ensure every modification is formally certified, protecting the structural integrity of the entire building.

We apply a Project Governance approach to site logistics. This includes a strict waste-management plan (using smaller, frequent removals instead of skips), advanced dust-screening, and daily communal area cleaning. By maintaining professional site conduct, we ensure your project proceeds without damaging neighborly relations or incurring management board fines.
