Structural Openings & Knock Throughs in Norfolk & Suffolk

A structural opening involves modifying or creating an opening in a load-bearing or non-load-bearing wall to accommodate new windows, doors, or open-plan layouts. This could mean adding a brand new set of patio doors, fitting a larger feature window, or combining two rooms into one light-filled space.

The placement of your doors and windows can dramatically change how your home feels and functions. Our structural openings service makes it possible to:

  • Create wider doorways or openings for sliding or bi-fold doors

  • Add new windows or rooflights to bring in more natural light

  • Knock through internal walls to connect spaces such as your kitchen and dining room

  • Replace small patio doors with full-height glazing for a modern, open look

Our expert team will handle everything, from structural design and steel calculations (RSJs) to building regulations compliance and finishing work, ensuring the transformation is both beautiful and safe.

The possibilities are endless, here are some of the most popular ways homeowners across Norfolk and Suffolk are reimagining their homes with Habify:

Frequently Asked Questions

Below, we’ve answered some of the most common questions about Structural Openings. If you’d like more details or have any other queries about our services, please don’t hesitate to get in touch.

A structural opening is when part of a wall is safely removed or altered to create space for a new window, door, or open-plan layout. This can involve installing RSJs (rolled steel joists) or lintels to support the remaining structure. At Habify, we carry out both internal and external openings from new garden doorways to large open-plan kitchen conversions.

Costs vary depending on the wall type and size of the opening, but as a guide:

  • Internal knock through (non-load bearing): £1,000 – £3,000

  • Load-bearing wall with RSJ: £3,000 – £6,000

  • New window opening: £750 – £2,500

  • New door opening: £1,000 – £6,000
