Built on Collaboration

Grifford interiors use MAS Design Consultants, working closely alongside them from conception through to planning and building regulations. Doing this enables us to accurately provide a detailed cost of build. 

We give a detailed break down of what’s included and what’s not. Starting from the foundations, drainage, masonry, roof, windows & doors and then moving onto any internals such as 1st & 2nd fix electrics, plumbing and joinery. Once we have this base, we can discuss inclusion of plastering, decoration, and fit out. 

We are 100% transparent and offer an in-depth knowledge and foresight to give you piece of mind.

Pricing Service

We pride ourselves on our pricing service. Because no one wants to find hidden costs mid-way through a project.  Whilst the most common way to provide quotes within the building industry is based upon a per cubic meter, we provide a full pricing breakdown so that you know exactly what to expect.

A Personal Touch

Renovation projects can be a messy business, but we want you to be comfortable in your home whilst builds are being completed. That is why we will always endeavour to treat your home as if it is our own. We will always use protective items and ensure a thorough clean up is taken out on completion of your project.

Wrap around extension with kitchen and bathroom refit.


“We chose to use Grifford Interiors for our building work due to the great reviews and Joe’s excellent communication and clear breakdown in costs when quoting for the job. Joe and his team were fantastic, they were friendly, efficient and particularly helpful in overcoming issues and possible delays that arose due to the architect and structural engineer.

We are delighted with the extension which has transformed our house into a spacious, light and family friendly home. I would recommend Joe and his team to anyone looking for good quality and reliable builders.”
