Major extensions
Substantial structural additions and reconfiguration that change how the whole home works.
Alpha Home Projects · Surrey & beyond
Your home project.
Properly run.
Major extensions, whole-home refurbishments and complex residential work, typically £200,000+ — led with the experience, control and direct accountability a significant home project deserves.
The right kind of work
Built for the projects that need more than a quote and a start date.
Large residential projects carry hundreds of decisions, dependencies and risks. Alpha Home Projects brings them under one experienced lead.
Whole-home refurbishment
Complete renovation, modernisation and services — carefully sequenced under one accountable team.
Complex remodelling
High-value structural alterations and multi-stage projects where planning and control matter.
A deliberate fit: We work on substantial changes to existing homes, generally with a construction budget of £200,000 or more and within roughly 20 miles of GU15 3DW.
If you are at an early stage, we can help establish whether the plans, timescale and approach suit our team.
Before work begins
Clear information, realistic expectations and agreed terms.
A substantial build cannot be reduced to a quotation and a start date. Before work begins, Alpha makes the key assumptions visible and establishes how the project will be run.
Make sure the information is ready
Planning drawings secure permission, but they rarely define every structural detail, finish, service or construction decision. We establish what is known, what remains undecided and which assumptions need confirming before a construction price is relied upon.
Understand why prices differ
The cheapest quotation is not automatically wrong — and the highest is not automatically right. What matters is whether the prices cover the same scope, specification, allowances and risk.
Agree how the project will be run
Scope, payment stages, programme, changes, insurance and responsibilities should be understood before work begins. A clear written contract protects both the homeowner and the builder.
Experience builds better homes
Construction knowledge at the point it matters.
Drawings are only the beginning. The real work is coordinating people, sequencing decisions and protecting cost, quality and momentum when the build is live.

What experience changes
Lessons carried into every new project.
A project we had originally priced was awarded on a substantially lower quotation. After workmanship and structural problems, the original contractor was replaced and the eventual cost rose beyond £200,000. The lesson is not “choose the highest price”. It is to establish why quotations differ before choosing either.
On an earlier project, the existing roof had not been opened up before the design was priced. Once work began, the rafters were found to be incapable of supporting the proposed alteration. Rebuilding added around £40,000 and six weeks. That experience changed how we approach projects involving unseen existing construction: targeted investigation before site can prevent an assumption becoming an expensive surprise.
Good questions, early answers
Before we get started.
Every substantial home project is different. These are the questions we are most often asked at the outset.
What size projects do you take on?
We focus on major changes to existing homes, generally with a construction budget of £200,000 or more. The scope and complexity matter as much as the initial figure, so an early conversation is worthwhile if your budget is still taking shape.
When should we get in touch?
As soon as you are considering a substantial extension or refurbishment. We can discuss the likely scope and build approach while the design is developing; you do not need a finished tender pack to make an initial enquiry.
Can you price from planning drawings?
Planning drawings are enough for an early conversation, but rarely enough for a responsible fixed construction price. Technical drawings, structural information, specifications and clear decisions about finishes and services help make quotations more complete and comparable.
What contract and terms will we use?
Every project should have a clear written contract setting out the agreed scope, price and payment stages, programme, insurance, responsibilities and how changes will be handled. The appropriate form depends on the project, and we will explain the proposed terms before either side commits.
How are changes during the build handled?
Changes happen, but they should not be allowed to become surprises. Wherever practical, variations are described and agreed in writing, with their cost and programme effect made clear before the additional work proceeds.
Where do you work?
Our core working area is roughly 20 miles from GU15 3DW, covering parts of Surrey, Berkshire and Hampshire. Send us the property postcode and we can confirm whether it is within our usual area.
Can we stay in the house during the work?
That depends on the extent and sequence of the works, particularly any changes to the kitchen, bathrooms, heating or electrics. We would talk through the practical options with you as the programme takes shape.
Who will lead our project?
Alasdair leads the construction side directly, coordinating the core team and specialist trades. You will have a clear point of contact for the decisions and issues that arise during the build.
