Arboricultural Consulting for Architects & Engineers

At Thor's Trees, we love working with architects and engineers across North London and Hertfordshire. We understand the headaches trees can cause in your design process, and we're here to turn those potential problems into design opportunities. Our friendly team knows exactly how to translate complex tree information into practical design guidance you can actually use.

Our constraints planning gives you a clear picture of what trees you've got and how they might affect your plans.
We'll map out all the root protection areas and identify which trees are worth designing around and which ones honestly aren't worth the trouble. Everything comes to you in formats that work with your design software, so you can just plug the information straight into your drawings. No more guesswork about how close is too close!

Once your initial designs are ready, we'll look at how your plans interact with those trees we surveyed. Our impact assessments are straightforward and practical, spotting problems before they become expensive worries.

We suggest sensible solutions that keep both your design vision and the trees happy. Whether it's adjusting foundation types or tweaking service routes, we'll find that sweet spot where good design and tree protection come together. Planning officers love this thorough approach, which makes your applications run much smoother.

We'll get those tree issues sorted before you submit anything to planning. Our pre-application support helps you navigate the sometimes confusing world of tree-related planning policies. We'll tell you straight which parts of your scheme might raise eyebrows with the tree officer.

We're happy to join those early planning meetings too, where we'll explain the tree aspects of your scheme in a way that makes sense to everyone. Having us in your corner from the start shows planning authorities you're taking trees seriously, which goes a long way toward getting that approval you need.

We've been working alongside architects and engineers for over 10 years now, so we really understand your world. We don't bombard you with technical tree talk, we translate everything into practical guidance that makes sense for your design process.
Our reports are clear, straightforward and designed to be genuinely useful rather than just ticking boxes. From those early concept sketches right through to seeing your finished building stand proud, we're here to make the whole process smoother and more successful.

Basements need careful planning when trees are nearby. Digging can change how water moves through soil and affect tree roots. We'll look at your basement plans and suggest practical adjustments that protect both the trees and your design vision. Often small changes to the design can make a big difference to tree health while still giving you the space you need.

Yes! Beyond saving existing trees, we can advise on new planting that enhances your scheme. Smart tree placement and species selection can boost your sustainability credentials and add real value to your development. Planning authorities look favorably on well-considered green elements, including a Biodiversity Net Gain (BNG) plan where necessary, which can help smooth your application process.

All our surveys follow the British Standard for trees in construction (BS5837) and work alongside NHBC 4.2. We make sure your planning submissions have exactly what the tree and planning officers are looking for, presented clearly and professionally. Our documentation gives you solid backing when your proposals are reviewed.

We've helped many architects solve this common challenge. There are several proven methods for creating level access and pathways near trees without damaging roots. From special surface materials to clever construction approaches, we can help you meet accessibility needs while keeping trees healthy.

Yes, we can provide tree valuations using methods that councils recognise. This helps determine fair replacement planting when trees need to be removed. While keeping good trees is usually best, sometimes removal is necessary. We'll guide you through the process to ensure you meet planning requirements properly.
