General Building & Roofing


Extensions are a very cost-effective way of making your home larger and are generally much cheaper and less disruptive than moving home or renovating. Professional home extensions can increase the value of your home significantly. We are experienced in working with architects and planners and have regular contact with building inspectors in the private and public sector.  All extensions are built to the highest standards and current building regulations.

All home extensions are fully projected managed. Throughout your project, we will be available to discuss all aspects of your project and will keep you appraised of the entire process from start to finish. Upon completion of your project, you will receive a guarantee for the works, your building regulations certificate and most importantly a wonderful new space.

Customer satisfaction, minimum disturbance, competitive pricing and completing the project on time are our main priorities. Tetrad Home Ltd are fully insured with Public Liability of £10m and Employer’s Liability of £5M and all our building work is guaranteed. We operate a Health and Safety policy, and all employees & subcontractors have the required certification.

So, how much does an extension cost? As a rough guide, a budget extension would probably cost you around £1,500 per m2, a standard finish would be around £1,750 per m2 and if you like a luxury finish it would probably cost you around £2,000 per m2. 

    Home Renovations

    Over the last 20 years our collective of experienced guys have undertaken many house renovations and home alterations in Northampton. Renovation projects can be internal or external including complete re-skinning of an existing home to drastically improve the appearance. Both interior and exterior renovation will add significant value and desirability to your home.

    Loft Conversions

    The roof space in your home generally makes up 30% of the square footage of your home. Unlocking this space by converting it into a light airy insulated area can be a real benefit to your home and add significant value and utility. In order to be able to convert a loft the minimum height must be 2.1 metres, if the height is lower it is possible to lower the floor and ceilings below to create the minimum height.

    Garage Conversions

    By having your garage converted you gain a large amount of new living space for a variety of purposes and add significant value and utility to your home. Garages are easily and cost-effectively converted to make additional living space and can increase the value of your property.

    Your converted garage can be used for many purposes for example – playrooms, granny annexes, home offices or large extensions to your kitchen area.

    Our skilled teams of builders will complete the project to an extremely high standard, on time and on budget.  Tetrad Home Ltd also carry out home extensions, attic conversions and Bi-Fold doors always providing excellent customer service and quality workmanship.
