Commercial

Support from feasibility through to completion

Architectural services, project management and NEC4 contract administration for commercial, industrial and education projects across Sussex and Hampshire.

Residential

Your house can probably do more than you think

Extensions, whole-home renovations and new houses across the Sussex coast and Downs. We take residential projects from first ideas through Planning and Building Regulations.

THE FIRST STEP

Find out what your house will allow — before you commit to a design

Most people arrive with a question that sounds simple and is not: can we do this, will we get permission, and what will it cost to build?
A Feasibility & Options Study answers all three, in writing, in about three weeks.
£625 + VAT (£750 total payable)
Credited in full against your design fee if you go ahead

Why Coastline

Architect-led

You work directly with a RIBA Chartered Architect, not a salesperson and a drawing office

Planning first

We test the planning position before you commit to a design, not after

Designed in 3D

You see and understand the proposal before the decisions get expensive

Honest about scope

We tell you what is included, what is not, and what it will cost, in writing

Most of our clients started with a room they had stopped using

The old conservatory

The new vaulted extension
