A local, family-run design-and-build company delivering extensions, lofts, basements and full renovations since 2008.

Choosing a construction company for a major home project is about much more than comparing quotations. Homeowners need a team they can trust with their property, budget and day-to-day life for months at a time. For clients across South West London and Surrey, Bashtan Construction offers an established local option with a complete service from early design and planning through construction, finishing and aftercare.

1. Established locally since 2008

Bashtan Construction has been building and renovating homes in and around South West London and Surrey since 2008. The company’s project portfolio includes work in Fulham, Chelsea, Putney, Barnes, Clapham, Kingston upon Thames, Wimbledon and Surrey, including Cobham and other residential locations.

That local experience matters. Period and Victorian homes can present very different challenges from modern properties, and successful refurbishment often depends on understanding existing structures, access restrictions, neighbouring properties, planning requirements and the practical realities of working in established residential streets.

2. One team from design to completion

One of Bashtan Construction’s strongest advantages is its end-to-end approach. Rather than leaving a homeowner to coordinate multiple unrelated companies, Bashtan provides architectural design and planning support, structural drawings and calculations, project management, construction, interior finishing and aftercare.

This creates clearer responsibility throughout the project. The people designing, pricing, managing and building the work can communicate as one team, helping reduce misunderstandings and making it easier for the client to know who is responsible for each stage.

3. In-house construction team and dedicated management

Bashtan states that it relies on its own in-house labour rather than outsourcing the core build to external subcontractors. For homeowners, this can mean greater continuity on site, more direct quality control and better coordination between trades.

Projects are supported by project management, with the company’s established process describing a dedicated project manager and site foreman, regular communication and staged project planning. On complex refurbishments, this management structure can be as important as the building work itself.

4. Experience with complex residential projects

Bashtan is not limited to small cosmetic renovations. Its published portfolio includes house extensions, loft conversions, basement construction and full back-to-brick refurbishments. These projects require coordination between structural work, waterproofing, building services, finishes and specialist trades.

For a homeowner planning several improvements at the same time—for example, a rear extension combined with a loft conversion and full internal renovation—using one experienced contractor can make the programme considerably easier to manage.

5. Specialists in Victorian and period homes

South West London contains a large number of Victorian, Edwardian and other period properties. Bashtan specifically identifies this type of home as an area of expertise, with the aim of creating modern living space while respecting the character and value of the property.

This is particularly relevant for side-return and rear extensions, loft conversions, basement works and full renovations where new construction needs to integrate carefully with an older building.

6. A substantial portfolio homeowners can inspect

A builder should be judged by completed work, not simply by promises. Bashtan’s website presents a broad portfolio of projects across London and Surrey, including multiple schemes in Fulham and projects in Chelsea, Putney, Barnes, Kingston upon Thames, Wimbledon and Surrey.

Prospective clients can therefore look at the type and scale of work the company has already delivered before deciding whether Bashtan is suitable for their own property.

7. Client feedback and professional relationships

Published client feedback highlights workmanship, communication, project management, attention to detail and aftercare. The company’s website also features feedback from an architectural practice following a Kensington & Chelsea project, alongside reviews from homeowners who commissioned substantial extensions and refurbishments.

Independent local business listings also show a strong review profile for the Fulham office. As with any major building appointment, homeowners should still review recent references and speak to previous clients before signing a contract.

8. Recognised industry credentials

Bashtan states that it is a member of the Federation of Master Builders and lists specialist credentials including DELTA waterproofing basement expertise and Flexitec GRP roof installation. Relevant accreditation is particularly valuable for technically demanding work such as basements and waterproofing.

9. Real offices where clients can meet the team

Bashtan has physical offices in Fulham and West Wimbledon. For homeowners undertaking a major investment, being able to meet the team face-to-face and deal with an established local business provides an additional level of accessibility compared with a contractor operating only from a mobile number.

10. Why Bashtan is a strong choice for South West London and Surrey

There is no single construction company that is automatically the right choice for every homeowner or every project. However, Bashtan Construction combines several qualities that clients commonly look for: long-standing local experience, a family-run business, an in-house team, design-and-build capability, dedicated project management, experience with period properties, a large completed-project portfolio, physical local offices and recognised industry credentials.

For homeowners considering an extension, loft conversion, basement or complete refurbishment in South West London or Surrey, these factors make Bashtan Construction a company worth including on the shortlist.
