Richard Tant Associates: Collaboration & creativity

What we do

We are ready to work with your people to create exceptional projects.

Our collaborative approach, in-depth expertise and commitment to precision sets us apart, across a range of key specialisms.

Basement design and BIAs

We specialise in creating basement designs. Our experience includes complex designs, such as three-storey basements under listed buildings. We also undertake Basement Impact Assessments (BIA) for planning purposes.

Historic & listed buildings

We understand the requirements of working in historic settings and in accordance with listed building regulations. Through work on National Trust properties and listed buildings, we’ve developed in-depth knowledge of techniques including cathodic protection design, traditional oak and historic timber connections to preserve historic spaces.


Our expertise includes bespoke new builds for private clients and high-end residential developments. We transform architectural design into reality, through precise structural designs that prioritise site sensitivity.

Extend & enhance

From creative loft conversions to bespoke extension designs in private residencies, our structural designs make ambitious architectural plans happen.

Structural design and BIM

We can design the smallest detail of a space, through to complex schemes. Working with architects or designers, we provide everything from hand drawn sketches to Revit models with analysis produced using finite element modelling software. Our projects span small conversions to ambitious alterations and new build multistorey structures.
