NovESS Developments / Zensiri
ESS Developments moved from construction and project-management work into its own residential development relatively recently, with the company dating its residential track record from 2019. Founder Gavin Perfect is presented by ESS as having more than 20 years of engineering, project-management and construction experience in Thailand and internationally. The Zensiri name is now used across pool-villa and low-rise condominium projects in Pattaya and Koh Chang. For a buyer, this is a small private developer with some completed schemes, not a listed property group with extensive public financial disclosure.

Overview
ESS Developments moved from construction and project-management work into its own residential development relatively recently, with the company dating its residential track record from 2019. Founder Gavin Perfect is presented by ESS as having more than 20 years of engineering, project-management and construction experience in Thailand and internationally. The Zensiri name is now used across pool-villa and low-rise condominium projects in Pattaya and Koh Chang. For a buyer, this is a small private developer with some completed schemes, not a listed property group with extensive public financial disclosure.
Track record
ESS now has several concrete delivery milestones. Its official history lists Serenity Jomtien Villas as a 27-villa development delivered over 2020–2022, and Serenity Residence Jomtien as the company's first condominium, with 56 units completed in early 2023. Zensiri Midtown Villas in central Pattaya contains 26 pool villas; independent property databases report completion in May 2025, broadly matching ESS's own 2023–2025 timeline. The next development cycle is materially larger: Zensiri Estate Jomtien has 26 villas and the adjoining Zensiri Residences Jomtien has 126 condominium units in two low-rise buildings, with ESS stating that both launched in November 2024 and construction began in 2025. Buyers therefore have completed schemes to inspect, but much of the current Zensiri pipeline has not yet built a long operating history.
Segments and prices
ESS's Pattaya product mix centres on private pool villas and low-rise condominiums. Zensiri Estate Jomtien offers three- to five-bedroom villas of roughly 339–417 sqm, while Zensiri Residences Jomtien provides one- to three-bedroom apartments across two seven-storey buildings. At Mabprachan, Zensiri Lakeside adds another villa format with 21 three- to five-bedroom homes. There is no stable public portfolio-wide price schedule, and third-party asking prices change over time, so a single ESS price band would be misleading. Buyers should compare the actual unit or villa quotation, including price per square metre or plot size, specification, furniture, payment schedule and post-handover charges.
Geography
ESS is concentrated on Thailand's Eastern Seaboard. Its Pattaya developments span Jomtien, central Pattaya and the Mabprachan Lake area, while Koh Chang hosts both villa and boutique condominium projects. This concentration is useful for due diligence because completed developments can be inspected in the same regional markets where new stock is being sold. It also means ESS is not geographically diversified across Thailand, so project performance is more exposed to Pattaya and Koh Chang demand and should be assessed at the individual submarket level.
Reliability and public record
A useful positive signal is that ESS can point to completed developments such as Serenity Jomtien Residence, Serenity Jomtien Villas and Zensiri Midtown Villas rather than relying only on future-project renders. Independent industry coverage also connects Gavin Perfect to those developments and corroborates his Pattaya activity. The limitation is the company's private status and the much thinner corporate disclosure available compared with listed Thai developers. The public sources reviewed for this profile do not provide recurring audited group financial statements. Completed projects therefore support an execution record, but the financial position of any current development still needs project-level verification.
What to verify
The exact contracting entity is particularly important with ESS. The official website footer names ESS Group Asia Co., Ltd., while third-party records for Zensiri Midtown identify ESS DEVELOPMENT CO., LTD. as developer; the Zensiri brand alone does not establish who owns the land or owes the buyer delivery obligations. Before paying, buyers should match the seller named in the agreement to the landowner, payment recipient, construction approvals and payment schedule. For an off-plan condominium, a foreign buyer should also confirm foreign-quota availability and the required remittance evidence. Villa purchases need a separate land review. ESS markets a registered 30-year land-lease structure through a Thai leasing company and describes renewal arrangements, but any future renewal depends on the legal and contractual structure and should not be treated as an automatically guaranteed 60- or 90-year registered term. The title deed, lessor, registered term, renewal clauses, leasing-company charges and ownership of the building itself should all be reviewed independently.

Frequently asked questions
When did ESS Developments begin its own residential projects?
ESS dates its own residential development activity from 2019. The company attributes more than 20 years of prior engineering, construction and project-management experience to founder Gavin Perfect, but that personal career history should not be counted as completed developments delivered by ESS itself.
Has ESS completed projects in Pattaya?
Yes. ESS's published history identifies Serenity Jomtien Villas and Serenity Residence Jomtien as completed, while Zensiri Midtown Villas was completed in 2025. Those properties give buyers physical reference points for construction quality and post-handover condition.
Is Zensiri a separate developer?
In the sources reviewed, Zensiri functions as the project brand used by ESS Developments rather than as a separately documented development group. The sale agreement should still be checked for the exact legal seller rather than relying on the brand name.
Can a foreign buyer own a Zensiri condominium unit freehold?
Foreigners can own units in a registered Thai condominium subject to the statutory foreign-ownership quota, which is capped at 49% of the aggregate condominium unit area. The specific unit must therefore be confirmed as available within that quota, with the required foreign remittance documentation.
Does an ESS land lease guarantee two additional 30-year terms?
A future renewal should not be treated as an automatically registered 90-year right. Thailand's general framework provides for a registered lease term of up to 30 years, while later renewal depends on the lessor's consent and the applicable contractual conditions. The specific ESS lease should be reviewed independently by Thai counsel.
