Our services
Our Flat Conversions Service
Our Flat Conversions service revamps your flat into a practical and inviting area, customised to suit your requirements. Our team transforms properties with precision and care, ensuring seamless transitions and maximising space utilisation.
A good conversion is mostly decided on paper: where the stairs and the entrances go, how each flat gets daylight, and how the walls and floors between homes keep fire and noise apart. Our architects plan all of it with you before a fixed price is agreed, then the same team builds it.
Trust Linx for comprehensive residential building services that are tailored to exceed your expectations, from extensions and loft conversions to new build homes and refurbishments.
- Structural integrity
- Fast delivery
- Quality, professional standards
- Dedicated team support

Who it is for: homeowners making the most of a large house, landlords adding units to a portfolio and developers converting buildings for sale or rent.
Houses into flats
Splitting a family house into self-contained flats, each with its own entrance, kitchen and bathroom.
Lofts and upper floors
Adding a flat in the roof or reworking the upper floors, often alongside a loft conversion.

Final snagging, deep clean, Building Control sign-off & handover
No obligation • Free consultation • Reply within 24 hours
Usually, yes. Turning one house into two or more self-contained flats is normally a change of use that needs planning permission from your council. Our in-house architects check what your council will allow, prepare the drawings and manage the application for you.
Each flat has to meet Building Regulations in its own right — fire separation between the flats and a safe escape route, sound insulation between floors and walls, ventilation, drainage and energy efficiency. We design for these from the start and arrange the Building Control inspections and sign-off.
Conversions start from £28,000 and typically take 8–12 weeks on site. The figure for your property depends on its size, the number of flats and the structural work involved, so every project starts with a free survey and a fixed-price quote.
Yes. One LINX team designs the conversion, secures the approvals and builds it, with a project manager as your single point of contact — and the structural work carries our workmanship guarantee.
