We have used Squarepoint twice for party wall notices. On both occasions we received a high quality service with quick and clear communication every step of the way. Would recommend.

Adam did a survey of our roof for us as we had had various leaks which numerous "fixes" hadn't yet sorted. I was really impressed with how Adam talked me through what he would do and was really practical about how he'd get access etc, as well as working with the roofers we then used to make sure this fix was effective. I felt like he understood what we needed. Really pleased with the service!

Perfect service! Mr Adam Graham has kindly agreed to do a level 3 survey for our flat. The report was extremely thorough and he has answered all my questions with lots of details. I would definitely recommend them for anything that requires a qualified surveyor!

We have dealt with Adam from Squarepoint Surveyors on a number of occasions, mainly during a party wall dispute with our neighbour. He has been incredible helpful, knowledgeable and professional. Our circumstances weren't the easiest, Adam has been a fantastic help and we cannot recommend him enough.

I accidentally bumped onto the Squarepoint contact and I'm so glad that I did because I can't recommend Adam enough! He is extremely patient, friendly and helpful throughout the entire process, both my neighbours ended up liking him too!

Very pleased with the professional service provided over a party wall issue that we had with overly sensitive neighbours during the build of our rear extension. Having research several other surveyors, my wife and I felt that Squarepoint was also fairly priced. Were we to consider doing any future building work, we would definitely look to use Squarepoint again.

We used Squarepoint to complete a party wall award for some works we were undertaking and they dealt with it in a very helpful and timely manner. We were very impressed with the professional service provided and would definitely recommend.

Building Alterations Surveyor

At Squarepoint Surveyors, we provide our clients with expert assistance regarding building extensions and alterations to their commercial property. Many businesses in London are maximising the space available to them, either by converting disused areas like basements and former warehouse space, or by constructing extra rooms on empty land. In both cases, significant structural alterations will be required, and professional assistance from a Chartered Surveyor experienced in this field is essential.

Making Alterations to Business Premises

When making alterations to business premises, there are many factors to consider such as getting the necessary planning permissions and building regulations approval. Our surveyors can guide you through this process and ensure any proposed changes comply with regulations. We can produce all the required plans and documents needed when applying for permissions.

What Does a Tenant Need to Consider before Making Alterations?

If you are a tenant, it is important to check your lease and get consent from your landlord before carrying out any alterations. The lease will likely specify what changes you can make. Our surveyors can review your lease and advise if consent is needed. We can also liaise with your landlord on your behalf. It’s key that any alterations do not negatively impact the landlord’s interests.

Carrying Out Alterations to Commercial Lease Premises

For leaseholders, we can provide guidance on best practices when altering commercial property. This includes advising on designs that are reversible and cause minimal damage. We also ensure any changes meet building regulations and planning permission requirements. Our aim is to facilitate alterations that improve your premises while respecting the landlord’s interests.

How are the perspectives of a landlord and tenant likely to differ?

Landlords will want to protect the value of their asset while tenants will want to maximise the usefulness of the space. Our expert surveyors balance these perspectives, advising tenants on achievable changes while ensuring landlords’ concerns are addressed. Clear communication is key.

Where to start when a tenant wants to make alterations

Tenants should begin by reviewing their lease and checking if consent is needed. We can then assess if the proposed alterations are feasible and align with regulations. Advising on reversibility and minimal damage is also key. With our experience, we guide tenants through the entire process.

How do the proposed alterations interact with other clauses in a commercial lease?

When advising tenants, we carefully review how the proposed changes align with all lease clauses covering property usage, consent requirements, and building obligations. Our aim is avoiding any breach of lease while still achieving the tenant’s goals. We get into the details so you don’t have to.

Our service is tailored to support commercial enterprises with building extensions and alterations, including guidance with Planning Applications, Building Regulation compliance and a complete range of tender documents (including specifications for contractors to quote and schedules of work). We can help you determine works that fall under ‘Permitted Development’, and whether Notice must be served to adjoining property owners under the Party Wall etc Act 1996.
