Altering the layout of your house can be a great way to open up new spaces and improve the way you use your home, should you wish to create a larger kitchen, kitchen dinner, bigger bathroom or simply remove built in cupboards to utilise more space. 

We can help you with our knowledge and advise you whether a wall is non load bearing and will not require any lintels / steels or is load bearing and requires additional support, if this is the case we can recommend a trusted Structural engineer.

We are just as happy to remove a simply built in structure, stud or non load bearing wall for you as we are carrying out complex alterations involving propping up walls and installing complex steel configurations. As members of The Federation of Master Builders we can supply you with an insurance backed guarantee against any structural defects to our work for varying amounts of times.

Removing walls can be a dusty dirty job and carrying out this type of work in a house that is occupied needs to be approached in a sensible and safe manner. We will always protect your family, property and its belongings from dust and always work in a clean, tidy and safe way for everyone.
